3 SINCE 2003 THE SHORTEST OVERALL LENGTH WIRELESS COMMUNICATION DIGITAL MEMS TECHNOLOGY The RST Digital MEMS Inclinometer Probe with industry leading system accuracy of ±2 mm per 25 m, shown connected to the cable. Since 2003, RST's Inclinometer systems have had the shortest overall length available for a given base length compared to competitive inclinometers. Undaunted, we ve forged ahead and improved on our very own industry-leading specifications. With a new minimum negotiable casing radius of 1.93 m, RST's Digital MEMS Inclinometer can still traverse a smaller radius bend than all other inclinometers available in the industry. A local microcontroller in the probe manages data collection, applies precision digital calibration, and provides a fast settling time which results in very efficient data collection. The Ultra-Rugged Field PC 2 functions as the data collector. It provides a high-level user interface, "at-the-borehole" data analysis and graphical comparison to previous data sets. CONNECTOR COMPARISON LEAST INTERFERENCE Interference Other Inclinometers RST's Inclinometer ULTRA-RUGGED Field PC 2 Rock solid and field ready for the most extreme environments. Wireless communication between the inclinometer control cable and the Ultra-Rugged Field PC 2 ensures ease of use and reliability since there is no concern with fragile connectors, cable related failure and reliability problems.

6 » inclinometer casing inclinometer systems tilt meters & sensors Inclinometer Casing RST s Inclinometer Casing is engineered to be assembled quickly and accurately for long and short term monitoring in the most adverse field conditions. RST Inclinometer Casing is suited to be installed in boreholes, embankments, piles, set into concrete or attached to structures. It s compatible with all commercially available inclinometer probes, including RST s MEMS Digital Inclinometer Probe. RST manufactures Inclinometer Casing with precision CNC technology. The casing serves as an access tube to guide a MEMS-based inclinometer probe in the two orthogonal directions of measurement. Changes in the output of the probe caused by the deformation of the casing, is proportional to the sine of the angle of inclination of the long sensor axis from vertical. These displacements are incrementally summed to provide profiles of total displacement versus depth. ICB0001M Glue and Snap Inclinometer Casing Snap Seal Inclinometer Casing RST Instruments manufactures two sizes of Inclinometer Casing in either Snap Seal or Glue & Snap coupling styles. Both provide alignment and displacement measurements in numerous applications. Also available as an option in both sizes, High Endurance Casing offers a very homogeneous tubing with extra reinforcement at the location of the connection between casing sections in order to ensure maximal torsional, compressive and bending strength. The High Endurance casing is used in situations where extra robustness is required. Contact RST for more details. manufacturing process Key to quality inclinometer casing is not only the material, but the quality and shape of the grooves. The inclinometer probe utilizes grooves in the casing to control the azimuth of the inclinometer probe. Clearly if the grooves spiral, azimuth control is lost, and the installation becomes questionable if not useless. Successive lengths of casing must join in such a manner so as to permit accurate tracking of the probe between successive casing sections. Spiral of the grooves cause misalignment between sections, causing the probe to jump out of the grooves. Groove shape must accurately mirror the probe wheels in order to prevent probe lateral movement. There are two methods of producing grooved casing: extrusion and machining. While the simplest and cheapest way is to extrude the grooves with the pipe, the extrusion process does not adequately address the parameters of spiral and shape. Machining the grooves produces a higher quality product. All RST casing is machined to insure the highest quality possible. RST casing is manufactured from non-recycled virgin ABS resin. While more costly than common PVC resin, ABS is preferred due to superior flexibility, stability and low temperature impact resistance. Using recycled resin degrades the performance of casing. applications Pilings Landslides and slope stability Subsidence control Under large storage tanks Embankment and dam stability Bridge pier, abutments deflection Areas next to large excavations features High precision, machined guide grooves. Low spiral Rad/3 m ( 0.3 deg./10 ft.) Meets or exceeds all applicable standards. Compatible with all commercial probe types and in-place inclinometer sensors. Self aligning, water and grout tight couplings. Integral coupling reduces assembly induced spiral by 50% over conventional separate coupling methods. Easy assembly. 70 mm (2.75 in.) and 85 mm (3.34 in.) OD sizes. Compatible with inductance, reed switch, magnetic, or mechanical settlement monitoring devices. Snap Seal and Glue & Snap integral flush couplings that minimize field installation time. Low temperature, impact and corrosion resistant ABS plastic. External key provides visual and tactile confirmation of proper installation. 6

OD GLUE & SNAP SPECIFICATIONS - 70 MM Traditional Inclinometer Casing installation methods dictate that screws or pop rivets must be utilized to hold the coupling in shear until the ABS solvent weld cement cures. The requirements for rivets is increased in deep boreholes. Snap Seal is the original O-ring sealed coupling system, which does not require glue, pop rivets, screws, or shear wires. This patented, innovative system allows casing sections to lock together while maintaining precise groove alignment and high collapse strength. The Snap Seal system is flush coupled for ease of installation in hollow stem augers and casing advancers. glue + snap casing Glue & Snap Inclinometer Casing is an improvement on the Snap Seal design and combines the best features of both installation methods with none of the disadvantages. Glue & Snap provides the speed and convenience of a Snap-together flush coupling combined with the low cost and high tensile/ high torsional strength of a glue joint. Installation is simply done by applying a bead of glue to the male end, snap casing together and insert downhole. As with Snap Seal, Glue & Snap Inclinometer Casing is flush coupled for simple installation. ordering info GLUE & SNAP SNAP SEAL 70 MM (2.75 IN.) 85 MM (3.34 IN.) 70 MM (2.75 IN.) 85 MM (3.34 IN.) Telescopic Section telescopic section When vertical heave or settlement is anticipated to exceed 1-2%, Inclinometer Casing Telescoping Sections must be used to allow axial movement of the casing while minimizing distortion due to vertical strain. Telescopic sections must be inserted appropriately extended or collapsed, to accommodate the expected settlement/rebound. Settlement sections are available in 70 mm (2.75 in.) and 85 mm (3.34 in.) and each section can accommodate up to 150 mm (6 in.) of compression or heave. As a general rule, telescopic sections are recommended for use in boreholes, whereas telescopic casing (see separate brochure) is used in embankments that are gradually raised, such as embankments and tailings dams. Another option to accomodate high settlement in boreholes is to use corrugated sleeving over the Inclinometer Casing (see Magnetic Settlement System brochure). 7

8 » inclinometer casing inclinometer systems tilt meters & sensors High Endurance Inclinometer Casing High Endurance inclinometer casing is comprised of ABS casing lengths with no machining at the end, except for an alignment notch. Casing sections of either 1.52 m (5 ft) or 3.05 m (10 ft) are assembled with external tight-fitting slip couplings. By construction, the High Endurance casing is therefore a very homogeneous tubing with extra reinforcement at the location of the connection between casing sections in order to ensure maximal torsional, compressive and bending strength. The High Endurance casing is used in situations where extra robustness is required. For instance, when the casing is installed in a soil formation or an embankment subject to relatively high settlement causing downdrag along the casing, the extra reinforcement ensures that all the strength of the casing will be mobilized. Shear resistance of the casing at the contact between different geological formations is also improved. If the expected settlement is very high, e.g. substantially more than 1-2%, telescopic sections or telescopic casing as described in separate data sheets, should be used. casing specs 70 MM (2.75 IN.)

9 » inclinometer casing inclinometer systems tilt meters & sensors Inclinometer Casing Anchor Control of buoyancy is an important detail of inclinometer casing installation in vertical boreholes and ducts. Buoyancy forces from water, and especially grout, may exert substantial uplift forces on casing prior to setting of the grout. The optimum location for restraint of this uplift force is at the bottom of the casing. Inclinometer Casing Anchors are available for 70 mm and 85 mm casing in both the Snap Seal and Glue & Snap coupling styles. A grouting version of the anchor is also available which houses a connector for an internal tremie line directly inside the anchor itself. Magnetic targets may also be integrated into the anchor assembly. operating principle The Inclinometer Casing Anchor is affixed to the bottom of the inclinometer casing prior to inserting it into the drill-rod/borehole. As soon as the anchor exits the bottom opening of the drill-rod/borehole, the spring loaded arms of the anchor are automatically extended to grip the borehole/duct wall. applications Pilings Landslides & slope stability Subsidence control Embankment and dam stability Bridge pier, abutments deflection Slurry and tie back walls Inclinometer Casing Anchor prior to arm extension. ordering info Grouting version of Inclinometer Casing Anchor.

10 » inclinometer casing inclinometer systems tilt meters & sensors Telescopic Inclinometer Casing Telescopic Inclinometer Casing is mainly used in embankments that are gradually raised, such as embankment dams and tailings dams, and where the casing will be subject, either locally or along its full length, to large amounts of settlement, typically more than 1 %. The Telescopic Inclinometer Casing is not recommended for use in boreholes where the entire string of casing sections is lowered all at once. For this latter situation, standard inclinometer casing (either Snap Seal or Glue and Snap) with telescopic sections should be preferred (see separate data sheet). Standard Telescopic Casing in non-extended state. Standard Telescopic Casing in extended state. The internal guide grooves for the inclinometer probe are precision machined and provide effective control of spiral, straightness, groove shape & depth. Alignment is maintained by screws in the casing and longitudinal slots in the couplings. The couplings accommodate up to 150 mm (6 in.) of compression or extension. Optional settlement flanges can also be attached to each casing section when it is installed incrementally in embankments. Heavy Duty Casing is also available by special order.

18 » piezometers Vibrating Wire Piezometers The RST Vibrating Wire Piezometer provides excellent long-term accuracy, stability of readings and reliability under demanding geotechnical conditions. Vibrating Wire Piezometers are the electrical piezometers of choice as the frequency output of VW devices is immune to external electrical noise, and able to tolerate wet wiring common in geotechnical applications. operating principle VW2100 Standard Vibrating Wire Piezometer VW2100-HD: Heavy Duty Vibrating Wire Piezometer VW2100-DP: Drive Point Vibrating Wire Piezometer Vibrating Wire Piezometers contain a high tensile steel wire with a fixed anchor at one end and are attached to a diaphragm in contact with water pressure at the other end. The wire is electrically plucked, with the resonant frequency of vibration proportional to the tension in the wire. This frequency induces an alternating current in a coil which is detected by the readout unit, such as the VW2106 Vibrating Wire Readout, and can then be converted to a pressure. The frequency output is immune to external electrical noise, and able to tolerate wet wiring common in geotechnical applications. Highly reliable lightning protection is incorporated in the vibrating wire transducer. The frequency signal is exceptionally immune from cable effects, including length (to several kilometers), splicing, resistance, noise pickup, and moisture. The vibrating wire coil circuit contains no semiconductor devices and has built-in ionized gas discharge device protection against transient damage. As a result, the vibrating wire piezometer provides excellent reliability in typical geotechnical situations i.e. long outdoor cables buried in saturated soil. The piezometer is equipped with a standard sintered stainless steel porous filter to prevent soil particles from contacting the diaphragm. A thermistor is built into the piezometer body to permit temperature measurement and temperature compensation of the piezometer. Standard construction is all stainless steel. RST vibrating wire piezometers are shipped with extremely tough polyurethane-jacketed foil-shielded cable for maximum endurance in field conditions. applications Assessing performance and investigating stability of earth fill dams and embankments. Slope stability investigations. Monitoring water levels in wells and standpipes. Monitoring pressures behind retaining walls and diaphragm walls. Monitoring pore pressures during fill or excavation. Monitoring pore pressure in land reclamation applications. features Field proven reliability and accuracy. Will tolerate wet wiring common in geotechncial applications. Immune from external electrical noise. Signal transmission of several kilometers. Cable lengths may be changed without affecting the calibration. High accuracy, IE a low pressure vented model will measure water level changes as small as 0.5 mm (0.02 in.). Thermistor for temperature measurement is standard. Negligible displacement of pore water during the measurement process. Hermetically sealed, stainless steel construction. Heavy case to minimize reading errors caused by overburden pressure. Data logger compatible. Integral lightning protection. 18 ELB0003X

A complete RSTAR L900 System uses L900 RSTAR Nodes at the sensor level, deployed in a star topology from a continuously active L900 RSTAR Hub, which consists of an L900 RTU interfaced to a FlexDAQ datalogger. The RSTAR Array Radio Series is based on the 900 MHZ, 868 MHz and 2.4 GHz spread spectrum band (country dependent) with extensive open-country range through use of simple dipole or directional antennae. A complete RSTAR L900 System is packet-oriented, and consists of slave RSTAR Nodes (DT2011B, DT2055B, DT2040 for VW instruments, DT4205 for 4-20mA transmitters and IC6560, IC6660 Tiltloggers, with a L900 Radio and Antenna kit) and a L900 RTU (master) which is a DIN-rail mounted module in the flexdaq enclosure. The RSTAR L900 nodes wake from low power and collect data from their attached sensors, such as Vibrating Wire Piezometers. This data, which includes RTU node address, address, node serial number, diagnostics, data, and CRC check, is then sent wirelessly as a packet to the L900 RTU. Upon reception to the flexdaq, the L900 RTU will issue an ACK signal which may include clock synchronization and rate data. The L900 RTU stores the data in a temporary register set which is overwritten as new data is received; there is an intermediate data logging g function in the RSTAR L900 Node. The datalogger within the flexdaq has ultimate responsibility for logging data. Power requirements for a single RSTAR L900 node is one lithium D cell. The flexdaq can be powered by a solar panel, batteries or AC power. L900 RSTAR Radios and Antennas can be ordered at a later date, or at time of initial ordering. An L900 RSTAR decal is also supplied for each unit to allow for proper identification. An RST DT2011B Single Channel Vibrating Wire Data Logger attached to an RST Vibrating Wire Piezometer. The radio antenna can be easily screwed into the connector within seconds. The DT2011B, DT2055B and DT2040 Data Loggers are all equipped with an option to add on a radio antenna and incorporate it into an RSTAR wireless system. As shown in the diagram on the right, a typical RSTAR L900 NODE consists of a data logger (DT2011B, DT2055B, DT2040 or DT4205) connected to a vibrating wire sensor such as an RST Vibrating Wire Piezometer, and a L900 RSTAR Radio & Antenna Kit. 32

All offer extreme flexibility in their design configurations and are custom made to accommodate a variety of sensor types as they pertain to the parameters of your project. The framework for building a FlexDAQ Datalogger is dependent on the type, number, precision, and speed of measurements required. Best of all, FlexDAQ Dataloggers arrive to you completely pre-assembled, pre-wired, pre-tested, and preprogrammed; ready to be put to work straight out of the box with minimal set-up. All FlexDAQ Dataloggers bear similarities in measurement and programming capabilities and can easily incorporate additional sensor and telecommunication options. Multiplexers, such as the RST Flexi-Mux, and/or SDM devices may be added to augment measurement and control capabilities that include: - adding extra sensors that can be monitored by the datalogger (RST Flexi-Mux) - providing non-volatile data storage and on-board battery-backed clock - on-board data processing - initiating measurement and control functions based on time or event - controlling external devices such as pumps, motors, alarms, freezers, valves, etc. - using PC support software or keyboard/display to program - operating independently of AC power, computers, and human interaction - consuming minimal power from a 12 Vdc source - interfacing with on-site and telecommunication devices such as telephone modems (including cellular and voice-synthesized), short haul modems, radio transceivers, satellite transmitters, and ethernet interfaces.

36 1 platform viewable Anywhere GeoViewer is a data viewer that provides flexible console viewing of large data sets from ADAS (automatic data acquisition systems). The program runs on Windows, with full functionality under Windows Server. GeoViewer operates on a LabVIEW platform, which has facilitated the evolution of the product, to support multiple loggers, on-web serving of data, numerous devices, web events, mobile access etc. The robust, fast, feature-rich, ever-improving LabVIEW platform permits new functionality to be added readily. 36

37 DATA SOURCE & PRESENTATION ALARM FUNCTIONS Much GeoViewer data originates in data loggers which transmit their data by various logger-specific means to files which are locally or remotely accessible to the GeoViewer server. Because of this file model, any file with a public format which contains time-stamped data may be presented in GeoViewer: spreadsheets, databases, comma-separated text files, GPS data, public weather data, etc. Designed for efficient use, data presentation is typically shown as views as indicated below: MIMIC VIEW: - with stoplight (green/yellow/red/blue/grey for ok/warning/alarm/ alarm-off/stale data) buttons which drill down into other views LISTS VIEW: - with stoplight coloured numeric fields TIME SERIES PLOTS: - with one or more channels with alarm levels, different sampling rates EXAGGERATED PROFILES: - for inclinometers, tilt beams, etc. LINKED FILES: - installation photos, logger programs, calibrations, notes, all one mouse click away from the data Full featured alarms are available for all channels, calculations from channels, communication status, etc. The alarms include high/low warn and alarm levels, hysteresis, event triggers, alarm levels computed from data, device outputs, privilege alarm mask. It is suggested that not every channel be alarmed and alarms be implemented incrementally to minimize nuisance alarms. WEB FUNCTIONALITY GeoViewer utilizes Internet communications in numerous ways. Data acquisition may use wired or wireless web communication as a link in a communications chain, local and wide area networks may be used to access data files outside the GeoViewer server, back-up may use offsite resources. Mobile-Friendly Views End users may view data by remote computer or mobile device, and receive alarms by , text messages etc. Privileged users can maintain the system from offsite, typically by VPN (virtual private network) remote access. Because of the limited screen size of mobile devices, mobile-friendly views are typically required, with large buttons and reduced clutter. Viewing Controls Static web viewing is controlled by IP friend list. Advanced viewing, alarm acknowledge etc. is controlled by access licence and individual password. Maintenance at local or remote console per VPN typically uses customer IT security methods. CALIBRATION & COMPUTATION With all data storage in raw format, calibration is typically performed on-the-fly using a calibration database. Numerous functions are available: linear, polynomial, transcendental, relational across the entire system (not just within a logger). Deferred calibration is a powerful maintenance tool: if the calibration of a sensor is found to be incorrect, the appropriate calibration page is edited, and the entire record is automatically updated from the first reading. If a sensor is replaced, intermediate variables are created which point to the discontinuous record, each with an appropriate calibration, and a composite variable is created which switches from one intermediate variable to the other on the replacement date. BUSINESS MODEL GeoViewer is typically sold as a purchase/annual maintenance product; i.e. the customer owns the product and runs it on his or her server. The purchase cost is based on number of servers running (typically one), and the number of simultaneous advanced viewers. On- and off-site training and assistance are available. 37

38 » inclinometer casing inclinometer systems tilt meters & sensors Track Monitoring System The Track Monitoring System is intended for monitoring settlement and twist of railroad tracks which may be affected by nearby construction activity, such as tunnelling or adjacent excavation, or which are located near hazardous zones such as potential washout or landslide areas. The Track Monitoring System consists of bussed settlement sensors mounted longitudinally along the track alignment, typically with a mount spacing of 2 or 3 meters and one, or several, track twist sensors mounted perpendicularly to the settlement sensors. The settlement and twist sensors are based on the same MEMS devices used in the MEMS Tilt & Inclination Series of products from RST Instruments. These sensors are fully compatible with flexdaq dataloggers and the GeoViewer data display and management software. specifications ordering info applications ITEM Range ±15 Resolution (digital) ±2 arc sec.
