Foxboro differential pressure transmitters measure the force difference between the high-pressure and low-pressure ports. This pressure difference deforms a silicon sensor, generating an electrical signal. The internal microprocessor linearizes and temperature-compensates the signal before transmitting it as a stable 4 to 20 mA or digital HART/FoxCom output. Multivariable models combine DP, static pressure, and temperature to compute compensated mass flow.
