Differential pressure transmitter

Differential pressure 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 DX1151 / 3351DP intelligent type can communicate with the HART communicator, and use it to set, monitor or form a field monitoring system with the host computer. DX1151 / 3351DP on-site adjustable intelligent differential pressure transmitter can be separated from the hand-held controller, and can realize on-site zero adjustment and configuration by pressing keys.
