Smart Pressure Transmitter, Range 1-150 Inch W.C.

SKU: 3100D-3-FM-1-1-LCD

The Mercoid® Series 3100D Smart Pressure Transmitter is a microprocessor-based high performance transmitter, which has flexible pressure calibration, push button configuration, and programmable using HART® Communication. The Series 3100D is capable of being configured for differential pressure or level applications with the zero and span buttons. A field calibrator is not required for configuration. The transmitter software compensates for thermal effects, improving performance. EEPROM stores configuration settings and stores sensor correction coefficients in the event of shutdowns or power loss. The Series 3100D is FM or ATEX approved for use in hazardous (classified) locations. The 100:1 range-ability allows the smart transmitter to be configured to fit any application.

  • Product Applications
  • Flow measurement
  • Level monitoring
  • Filter or pump differential pressure
  • Critical process monitoring
  • Features
  • Configurable using zero/span buttons means no calibrator required reducing time to install and running
  • Range-ability and selectable engineering units, allows transmitter to fit many applications reducing the number of different transmitters to meet specifications
  • High accuracy (±0.075%) provides exceptional measurement for ensuring tight control and minimizing costly out of specification conditions
  • Automatic sensor temperature compensation improves performance of device for accurate measurement under different operating environments
  • Fail-mode process function stores configuration settings in the event of shutdown or power-loss provides for faster restart to getting application back on-line
  • A HART® Communication programmable device provides a reliable, long-term solution for plant operators who seek the benefits of intelligent devices with digital communication
