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.
