3100D-6-FM-1-1-LCD is a Mercoid® series 3100D explosion-proof smart pressure transmitter. This 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 approved for use in hazardous (classified) locations. The 100:1 rangeability allows the smart transmitter to be configured to fit any application. Typical applications include flow measurement, level monitoring, filter or pump differential pressure and critical process monitoring.
