The Mercoid 3100 series smart pressure transmitter is a microprocessor-based high performance transmitter, which has flexible pressure calibration, push button configuration, and programmable using HART Communication. The 3100 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 3100 series is FM or ATEX approved for use in hazardous (classified) locations. The 100:1 rangeability allows the smart transmitter to be configured to fit any application.

The Mercoid 3100 series is available in both a standard design (3100D) as well as a multiplanar (3100MP) design. The multiplanar design simplifies installation, saving operator time and money during set up. The 3100MP can be installed vertically without adaptors or brackets regardless of the process connection orientation. The multiplanar footprint fits standard manifold valves and averaging flow sensors.
