Mercoid® Series 3100D Explosion-Proof Smart Pressure Transmitter is
a microprocessor-based high performance transmitter, which has exible
pressure calibration, push-button conguration, and programmable using HART®
Communication. The Series 3100D is capable of being congured for differential
pressure or level applications with the zero and span buttons. A eld calibrator is not
required for conguration. The transmitter software compensates for thermal effects,
improving performance. EEPROM stores conguration settings and stores sensor
correction coefcients in the event of shutdowns or power loss.
The Series 3100D is FM or ATEX approved for use in hazardous (classied) locations.
The 100:1 rangeability allows the smart transmitter to be congured to t any
application.
FEATURES/BENEFITS
• Congurable using zero/span buttons means no calibrator required reducing time to
install and running
• Range-ability and selectable engineering units, allows transmitter to t many
applications reducing the number of different transmitters to meet specications
• High accuracy (±0.075%) provides exceptional measurement for ensuring tight control and minimizing costly out of specication conditions
• Automatic sensor temperature compensation improves performance of device for
accurate measurement under different operating environments
• Fail-mode process function stores conguration settings in the event of shutdown or
power-loss provides for faster restart to getting application back on-line
Liquid & Gas
• A HART® Communication programmable device provides a reliable, long-term
solution for plant operators who seek the benets of intelligent devices with digital
communication
APPLICATIONS
Differential Pressure Transmitters,
• Flow measurement
• Level monitoring
• Filter or pump differential pressure
