Series 3100D Explosion-proof Differential Pressure Transmitter

HART® Communication, Push Button Configuration, Rangeability (100:1)

 

Mercoid® DWYER Series 3100D Differential Pressure Transmitter is a microprocessor-based high performance transmitter, which has flexible pressure calibration, push button configuration, and programmable using HART® Communication. The DWYER Series 3100D Differential Pressure Transmitter 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.

 

Features

• Configurable using zero/span buttons means no calibrator required reducing time to install and running
• Range-ability and selectable engineering units, allows transmitter to fit many applications reducing the number of different transmitters to meet specifications
• High accuracy (±0.075%) provides exceptional measurement for ensuring tight control and minimizing costly out of specification conditions
• Automatic sensor temperature compensation improves performance of device for accurate measurement under different operating environments
• Fail-mode process function stores configuration settings in the event of shutdown or power-loss provides for faster restart to getting application back on-line
• A HART® Communication programmable device provides a reliable, long-term solution for plant operators who seek the benefits of intelligent devices with digital communication
