IDP25 Intelligent Differential Pressure Transmitter

The Foxboro® I/A Series® Model IDP25 is an intelligent, multirange, 2-wire transmitter that provides precise, reliable, measurement of differential pressure providing the measurement range and performance of “two transmitters in one.” It transmit a 4 to 20 mA or digital output signal, as applicable, using HART®, or FOUNDATION® Fieldbus communication protocol for remote configuration, calibration and monitoring.


Long-term stability with drift of 0.015% URL per year stability over a ten year period.


Remote seals are required for operation and mounting. See Remote Seals for Pressure Transmitters
