| Thermo Scientific's MST2000 Series Loop Powered Multivariable SMARTFLOW Transmitter sets new standards for draft range Differential Pressure / Mass Flow measurement of air and gas flows. Combining Thermo Scientific'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 (MST2000 Hart Communications), 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 of Water Column full scale. Fully programmable and user friendly the MST2000 is capable of producing and displaying signals for Differential Pressure (Inches of W.) or for Flow (ACFM, SCFM, Lb/hr). A metric version is also available.
Optional isolated 4-20mA 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.
Standard Features:
- High Performance at Ultra Low Spans: Standard spans from 0.10 to 50 inches W.C. are available with a total accuracy of 0.15% of Span. Custom and compound ranges are also possible.
- Thermal Compensated Output: Each MST2000 has 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.
- 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 4-20mA output to a low 3.9mA 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 (or the metric version). Without these constants, or external inputs, only the D.P. will be a true signal.
Options:
- Intrinsically Safe Approved: The MST2000 is approved for intrinsically safe installation by Canadian Standards Association. MST2000 CSA Approvals.
- Integral High Pressure Blowdown Option: The MST2400 can be combined with an Integral High Pressure Blowdown System which is specifically designed to clean out Pitot Averaging Air/Gas Flow Meters used in processed with heavy particulate loading.
- Continuous Purge Option: Continuous purge of air to pitot averaging flowmeter. Spans of 0.25 Inch. WC or greater.
