Product Description

3051 Smart Differential pressure transmitter



With advanced microprocessor technology and state-of-art silicon pressure sensor, the 3051 series intelligent differential pressure transmitter provide an accurate, reliable and economic solution for wire range of pressure measurement application. To reach the best performance, every silicon pressure sensor in our transmitter is specially temperature compensated, non-linear compensated, tested and screened before assembly.



Measurement of fluid flow, liquid level, volume and mass



Real time configured during operation

The pressure signal can be linear corrected

Reserve connection protection on circuit board, current limitation

The configured parameters keep same after stored in E PORM

High precision, high stability

Rough and anti-vibration components and plug-in PCB

Explosive proof configuration

Sensor trim, zero trim and damp can be continuously adjustable



Measurement range:
