Intelligent pressure / differential pressure transmitter configuration: metal capacitive sensor, 4-20MA, 24V, 2 wire system, digital liquid crystal display head, HART protocol, mounting bracket!
The 3151GP pressure transmitter is used to measure the liquid level, density and pressure of liquid, gas or steam, and then convert it to 4 ~ 20mA DC signal output. 3151GP intelligent pressure transmitter can communicate with the HART hand controller, through which to set up, monitor or monitor the system with the host computer.
