Dwyer 3100 Explosion-Proof
Differential Pressure Transmitter
HART®, Push Button
Configuration, Hart® Rangeability (100:1)
The Mercoid® Series 3100 Smart Pressure Transmitter from Dwyer
Instruments is a microprocessor-based high performance
transmitter, which has flexible pressure calibration, push button
configuration, and is programmable using HART® Communication.
The Series 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 Series 3100 pressure transmitter
is FM approved for use in hazardous (classified) locations.
The 100:1 rangeability allows the smart transmitter to be
configured to fit any application.
