Emerson FPD 375 Fieldbus Pressure Transmitter

Product Brief Introduction The Emerson FPD 375 is a Foundation Fieldbus protocol intelligent pressure transmitter for precise pressure and level measurement in process applications.
Tag:

Technical Specifications Foundation Fieldbus H1 communication, configurable measuring range, 0.075% reference accuracy, IP67 housing, multi-variable measurement capability.

Functional Features Digital pressure and temperature measurement, self diagnostics, automatic temperature compensation, wide rangeability, fieldbus system integration.

Application Scenarios Process pressure measurement, hydrostatic liquid level, gas and steam pressure monitoring, petrochemical and refining processes.

Performance Parameters High measurement accuracy, excellent long term stability, fast step response, strong environmental resistance.

Material Composition 316 stainless steel process connection, silicon oil filled capacitive sensor, aluminum electronic housing, sealed terminal compartment.

Structural Characteristics Threaded process connection, integral explosion-proof housing, fieldbus cable connection, local zero and span adjustment.

Working Principle Detects process pressure via the capacitive sensor element, converts physical pressure into digital signal, and transmits pressure, temperature and diagnostic data over the Foundation Fieldbus network.

Installation Requirements Install on process piping via threaded adapter, connect fieldbus cable, perform zero point calibration after installation.

Usage Notes Calibrate the transmitter at specified intervals. Protect the sensor from overpressure and water hammer. Verify wetted material compatibility with process fluid.
