Pressure Differential Transmitter

Pressure Differential Transmitter

Pressure Differential Transmitter

Type intelligent pressure differential transmitter is used to measure the level, density and pressure of liquid, gas or steam, and then convert it into 4-20mA DC signal output. The intelligent differential pressure transmitter can communicate with the HART handheld communicator, through it to set, monitor or form an on-site monitoring system with the host computer. The intelligent differential pressure transmitter is a new product developed by Jinhu Tianxin according to on-site requirements. It can be separated from the hand operator and can be used to realize on-site zero adjustment and configuration operations through the button.
