MST2000 Loop Powered Multivariable SMARTFLOW Transmitter

MST2000 Loop Powered Multivariable SMARTFLOW Transmitter Brandt Instruments MST2000 Series Loop Powered Multivariable SMARTFLOW Transmitter sets new standards for draft range Differential Pressure / Mass Flow measurement of Air and Gas Flows. Combining Brandt s twenty plus years of experience in industrial process control with state of the art digital signal processing technology, the MST2000 is the most versatile, reliable, cost-effective and simplest to operate loop powered multivariable transmitter in the industry. The MST2000 is a HART compatible, loop powered (two wire ) device available in either a compact, NEMA 1 configuration for wall or panel mounting or a rugged fiberglass NEMA 4X enclosure for hostile environments. With a turndown capability of 10:1 the available draft ranges can be turned as low as 0.01 Inches W.C. full scale. Fully programmable and user friendly, the MST2000 is capable of producing and displaying signals for Differential Pressure (Inches of Water Column) or for Flow (ACFM, SCFM, Lb/Hr). Optional isolated 4-20 ma inputs are available for Absolute Pressure, External Temperature and a second Differential Pressure Transmitter. A HART Communications Module and Digital I/O Module are also available. All the optional modules can be installed in the field by the end user. MST2000 Standard Features High Performance at Ultra Low Spans: Standard spans from 0.10 to 50 Inches Water Column are available (custom and compound ranges are also possible) with a total accuracy of 0.15% of Span. Thermal Compensated Output: Each MST2000 has an onboard temperature sensor and is thermally compensated at the factory to eliminate thermal effects. Password Protection: The MST2000 provides for password security so that modifications to program variables can only be made by authorized personnel. Adjustable Damping: The standard time constant is 500 msec but is user programmable from 0.5 to 5 seconds in 0.5 second intervals. LCD Display and Integral Keypad: A large, high contrast, easy to read LCD display and integral keypad allow the user to effortlessly program the MST2000 for optimal process conditions. Programmable Alarms: User selectable transmitter fault conditions can be programmed to set the 4-20 ma output to a low 3.9 ma or high 21.0 ma state. User can also select HI/LO process conditions to control the optional digital outputs. RTD Input: A non-isolated 4 wire RTD input connection is supplied for external temperature input. Integral Test Jack: Allows the user to monitor the ma output of the MST2000 without disconnecting the loop. Programmable Constants: When external temperature and absolute pressure signals are unavailable, these variables can be programmed in as constants, allowing the end user to select an output signal which will represent ACFM, SCFM or Lb/Hr. Without these constants, or external inputs, only the D.P. will be a true signal. MST2400: NEMA 4X Enclosure MST2000 Isolated Input Modules The MST2000 can be optionally configured with up to three (3) Isolated 4-20 ma input modules for true mass flow measurement. The input range for each input module is software rangeable by the end user. Any combination of the three can be mounted at the factory or field mounted by the user to upgrade process capabilities. Temperature Input Option: Accepts a 4-20 ma input from an external temperature transmitter. Absolute Pressure Input Option: Accepts a 4-20 ma input from an external absolute pressure transmitter. An optional integral absolute pressure transmitter can be mounted in the MST2400 enclosure. External Differential Pressure Input Option: Accepts a 4-20 ma input from an external differential pressure transmitter. A second differential input can be used to extend the available range to provide up to 2% flow rate accuracy over a 25:1 flow range. MST2000 Digital I/O Module The MST2000 can be optionally configured with (1) one digital input and (2) two digital outputs. This option is capable of either being installed at the factory or in the field. Digital Input: Accepts external signal to trigger events, such as a blowdown sequence. The MST2000 will hold the last output signal throughout the duration of the event. Digital Outputs: For control of external devices (AutoZero Valve, High Pressure Blowdown Systems, Alarm Circuits, etc.). HART Communications Module An optional HART Communication Module can be installed to provide industry standard HART access to the MST2000. This option can be installed at the factory or in the field.
