3 Description of the measuring principle 1 Description of the measuring principle Measuring principle OPTISWITCH is a level sensor with tuning fork for level detection. It is designed for industrial use in all areas of process technology, preferably in liquids. The vibrating element (tuning fork) is energized piezoelectrically and vibrates at its mechanical resonance frequency. The piezos are fixed mechanically and are hence not subject to temperature shock limitations. If the vibrating element is submerged in the product, the vibrating frequency changes. This change is detected by the integrated oscillator and converted into a switching command. Typical applications are overfill and dry run protection. Thanks to its simple and robust measuring system, OPTISWITCH is virtually unaffected by the chemical and physical properties of the liquid. It functions even when exposed to strong external vibration or changing products. Fault monitoring The electronics of OPTISWITCH continuously monitors the following criteria: l strong corrosion or damage of the tuning fork l loss of vibration l line break to the piezo drive If one of these faults is detected or in case the power supply fails, the electronics takes on a defined switching condition, e.g. the output transistor blocks (safe condition). Function test The recurring function test serves to reveal potential dangerous errors that are otherwise not discernible. The function of the measuring system must be checked at regular, adequate intervals. There are two different possibilities to carry out a function test: OPTISWITCH with two-wire electronics in conjunction with a signal conditioning instrument. l Test key on the signal conditioning instrument OPTISWITCH with two-wire electronics in conjunction with a PLC. l Brief interruption of the connection cable to the PLC OPTISWITCH 5100 C, 5200 C OPTISWITCH level switches are available in standard and tube version. Thanks to the large array of available process fittings, housings and electronics versions, the instruments can provide an optimal solution for any application. They have all the current approvals and the tuning fork can also be polished, e.g. for applications in the food processing industry. The OPTISWITCH sensors are largely unaffected by product properties and do not have to be adjusted. The level switches are used in applications with process temperatures up to 250 C (482 F) and pressures up to 64 bar (928 psi). They detect liquids from g/cm³ ( lbs/in³). All electronics modules are qualified as overfill and dry run protection systems acc. to IEC and to SIL2 - in redundant version also in SIL3. Vibration Level detection in liquids 3

4 Description of the measuring principle OPTISWITCH 5150 C, 5250 C OPTISWITCH 5150 and 5250 have also a polished surface as well as hygienic fittings and are mainly used for applications with special hygienic requirements. 1.1 Application examples Chemical industry Solvents Fig. 1: Level detection in vessels with solvents Beside continuous level measurement, level detection is a major safety feature of storage tanks. Many modern sensors for continuous level measurement, however, are approved as overfill protection system, but a second, physically different measuring principle offers optimum safety and redundancy. Due to their versatile nature, OPTISWITCH vibrating level switches are the ideal solution for all applications having to do with the storage of liquids. A number of electrical and mechanical versions ensures simple integration into existing control systems. Advantages: l various electrical versions l product-independent l universal level detection for all liquids 4 Vibration Level detection in liquids

5 Description of the measuring principle Chemical industry reactors Fig. 2: Level detection in chemical reactors Because they prevent overfilling or dry running of pumps, sensors for level detection are an important safety element in reactors. Due to their universal applicability, OP- TISWITCH level switches are well suited for use in reaction vessels. Even high viscosities, temperatures up to 250 C and pressure up to 64 bar do not impair their function. To provide the required chemical resistance, high resistance materials and enamelled versions are available. In toxic products, the OPTISWITCH version with metallic process separation ensures a high level of safety. To prevent product leakage even in case of corrosion on the tuning fork, a glass seal is also welded in. This guarantees optimum safety. To provide optimal resistance to the measured medium, whatever its composition and corrosive properties may be, sensors made of 316L or Hastelloy, or sensors in plasticcoated and enamelled versions, are available. Due to their versatile nature, OPTISWITCH vibrating level switches are the ideal solution for all applications having to do with the storage of liquids. A wide range of electrical and mechanical versions ensures simple integration into existing control systems. Advantages: l various electrical versions l product-independent l completely gas-tight l high reliability l universal level detection for all liquids Vibration Level detection in liquids 5

6 Description of the measuring principle Water/Sewage water plants Fig. 3: Precipitants in sewage water processing Chemicals are required for sewage water treatment. They are applied to promote chemical precipitation in the process. Phosphates and nitrates are sedimented and separated. In addition to lime water and ferric chloride, various acids and lyes are stored for use in digested sludge treatment and neutralisation. These substances are subject to the regulations for water-endangering substances. In accordance with this, overfill protection systems must be mounted on storage tanks. Because they prevent overfilling of vessels containing toxic products, sensors for level detection are an important safety element. Due to their versatile nature, OPTISWITCH vibrating level switches are also well qualified for use with water-endangering substances. To provide optimal resistance to the measured medium, whatever its composition and corrosive properties may be, sensors made of 316L, Hastelloy, or sensors in plastic-coated or enamelled versions, are available. Advantages: l high reproducibility l high resistance materials such as PFA, ECTFE, Hastelloy C4, enamel Pipelines Fig. 4: Dry run protection in pipelines Monitoring of levels is also important in pipelines, as dry running often causes damage or complete breakdown of the pumps. 6 Vibration Level detection in liquids

7 Description of the measuring principle The OPTISWITCH level switch is recommended as dry run protection system, e.g. for drinking water pumps. With a fork of only 40 mm length, this level switch functions reliably even with small tube diameters. Advantages: l universal level detection for all liquids l adjustment and maintenance-free Food processing industry Fig. 5: Level detection and dry run protection in a tank storing milk The processes in food processing tanks, such as e.g. for milk, place heavy demands on the installed measurement technology. High pressures and temperatures are generated during sterilization and cleaning of the tanks. The implemented level measuring instruments and level detectors must meet the requirements of the hygienic system. The innocuousness of all wetted materials must be proven and optimum cleanability must be ensured through hygienic technical design. OPTISWITCH is installed for level detection and as dry run protection system. The tuning fork is highly polished for the use in sensitive foodstuffs such as milk. Advantages: l universal level detection for all liquids l high resistance sensor materials l adjustment and maintenance-free Vibration Level detection in liquids 7

10 Mounting information 3 Mounting information Switching point Socket Agitators In general, OPTISWITCH can be mounted in any position. The instrument must be mounted in such a way that the tuning fork is at the height of the requested switching point. The vibrating element should protrude into the vessel to avoid buildup. For that reason, avoid using mounting bosses for flanges and screwed fittings. This applies particularly to use with adhesive products. Agitators, equipment vibration, or similar, can subject the level switch to strong lateral forces. For this reason, do not use an overly long extension tube for OPTISWITCH 5200 C, 5250 C, but check if you can mount an OPTISWITCH 5100 C, 5150 C level switch on the side of the vessel in horizontal position. Extreme vibration in the system, e.g. caused by agitators or turbulence in the vessel, can cause the extension tube of OPTISWITCH to vibrate in resonance. This will cause increased stress on the upper weld joint. Should a longer tube version be necessary, you can fasten a suitable strut or guy wire directly above the vibrating element to steady the extension tube. This measure applies particularly to applications in Ex areas. Make sure that the tube is not subjected to bending forces through this measure. Inflowing material If OPTISWITCH is mounted in the filling stream, unwanted switching signals can be generated. Mount OPTISWITCH at a location in the vessel where no disturbing influence from e.g. filling openings, agitators, etc. can occur. Fig. 6: Inflowing material Flow Lock fitting Pressure/Vacuum If there is movement within the product, the tuning fork of OPTISWITCH should be mounted in such a way that the surfaces of the fork are parallel to the product flow. OPTISWITCH in tube version can be mounted with a lock fitting for height adjustment. Take note of the pressure specifications of the lock fitting. Keep in mind that the lock fitting must not be used with coated instrument versions. The process fitting must be sealed if there is gauge or low pressure in the vessel. Check if the seal material is resistant against the measured product and the process temperature. 10 Vibration Level detection in liquids

11 Electrical connection 4 Electrical connection 4.1 Preparing the connection Note safety instructions Take note of safety instructions for Ex applications Select power supply Select connection cable Always observe the following safety instructions: l Connect only in the complete absence of line voltage In hazardous areas you should take note of the appropriate regulations, conformity and type approval certificates of the sensors and power supply units. Connect the power supply acc. to the following diagrams. Oscillator SW60R and SW60C are designed in protection class 1. To maintain this protection class, it is absolutely necessary that the ground conductor be connected to the internal ground terminal. Take note of the general installation regulations. As a rule, connect OPTIS- WITCH to vessel ground (PA), or in case of plastic vessels, to the next ground potential. On the side of the housing there is a ground terminal between the cable entries. This connection serves to drain off electrostatic charges. In Ex applications, the installation regulations for hazardous areas must be given priority. The data for power supply are stated in the Technical data in the Supplement. OPTISWITCH is connected with standard cable with round wire cross section. An outer cable diameter of 5 9 mm ( in) ensures the seal effect of the cable entry. If cable with a different diameter or wire cross section is used, exchange the seal or use an appropriate cable connection. In hazardous areas, only use approved cable connections for OPTISWITCH. Select connection cable for Ex applications Take note of the corresponding installation regulations for Ex applications. 4.2 Wiring plans Relay output Fig. 7: OPTISWITCH oscillator with relay output 1 Control lamp 2 DIL switch for mode adjustment 3 DIL switch for switching point adaptation We recommend connecting OPTISWITCH in such a way that the switching circuit is open when there is a level signal, line break or failure (safe condition).

The instrument is used to control relays, contactors, magnet valves, warning lights, horns as well as PLC inputs Fig. 9: OPTISWITCH oscillator with transistor output 1 Control lamp 2 DIL switch for mode adjustment 3 DIL switch for switching point adaptation Fig. 10: OPTISWITCH Transistor output - NPN action 12 Vibration Level detection in liquids

13 Electrical connection Fig. 11: OPTISWITCH Transistor output - PNP action Contactless electronic switch We recommend connecting OPTISWITCH in such a way that the switching circuit is open when there is a level signal, line break or failure (safe condition). The contactless electronic switch is always shown in non-operative condition. The instrument is used for direct control of relays, contactors, magnet valves, warning lights, horns etc. It must not be operated without an intermediately connected load, because the electronics would be destroyed if connected directly to the mains. It is not suitable for connection to low voltage PLC inputs. Domestic current is temporarily lowered below 1 ma after switching off the load so that contactors, whose holding current is lower than the constant domestic current of the electronics, are reliably switched off. When OPTISWITCH is used as part of an overfill protection system acc. to WHG, also note the regulations of the general type approval Fig. 12: OPTISWITCH oscillator with contactless electronic switch 1 Control lamp 2 DIL switch for mode adjustment 3 DIL switch for switching point adaptation Vibration Level detection in liquids 13

16 Adjustment 5 Adjustment 5.1 Adjustment, general Fig. 18: Adjustment elements electronics module, e.g. OPTISWITCH relay output (SW60R) 1 Signal lamp (LED) 2 DIL switch for mode adjustment 3 DIL switch for switching point adaptation Switching point adaptation Mode switch Signal lamp (LED) Simulation key Characteristics reversal With this DIL switch (2) you can set the switching point to liquids with a density between 0.5 and 0.7 g/cm³ ( lbs/in³). In the basic adjustment, liquids with a density >0.7 g/cm³ (>0.025 lbs/in³) can be detected. For products with lower density, you have to set the switch to >0.5 g/cm³ (>0.018 lbs/ in³). The information about the position of the switching point relates to the medium water - density value 1.0 g/cm³ (0.036 lbs/in³). With mediums of differing density, the switching point shifts in the direction of the fork end, depending on the density and manner of installation. With the mode adjustment (min./max.) you can change the switching condition of the output. You can set the required mode (A/max. max. detection or overfill protection, min. B/min. detection or dry run protection). Diode for indication of the switching status (with plastic housing visible from outside) NAMUR electronics The simulation key is located in a recess on the upper side of the oscillator. Push the simulation key with a suitable object (screwdriver, pen, etc.). When the key is pushed, line break between sensor and processing unit is simulated. The LED on the sensor extinguishes. The measuring system must signal failure and take on safe condition when the key is pushed. Keep in mind that all downstream devices will be activated as long as the key is pushed. By doing this, you can check the correct function of the measuring system. NAMUR electronics The characteristics of the NAMUR electronics can be reversed with the DIL switch. You can choose between falling characteristic curve (switch position max.) and rising characteristic curve (switch position min.). You can thus have the desired current outputted. 16 Vibration Level detection in liquids
