IDP31 Intelligent Differential Pressure Transmitter

The Foxboro brand I/A Series System IDP31 differential pressure transmitter is a microprocessor-based smart transmitters that provides precise, reliable, measurement of differential pressure and features high performance and excellent stability. Capable of measuring gas, liquid, vapor, and liquid levels, it transmits 4 to 20mA DC analog and digital signals according to the measured differential pressure. It can also execute twoway communications using HART protocol, thus facilitating self-diagnosis, range resetting, and automatic zero adjustment.
