Micro differential pressure transmitter manual

1、 Introduction

The differential pressure transmitter produced by Xizheng Company is a pressure transmitter developed and produced independently using imported pressure sensors. Adopting anti-interference technology, circuit linearity, and temperature compensation technology, it has better anti-interference, linearity, and lower or ultra-low temperature drift coefficient. Its temperature drift coefficient is much lower than that of similar general products in China, and it is suitable for measuring gas, liquid, steam pressure and various corrosive media. Widely used in fields such as petroleum, chemical, metallurgy, power, light industry, machinery, etc. Zero point and full range can be adjusted on-site. The purpose of Xizheng Company is to survive with quality and develop with reputation.

4、 Electrical connection

5、 Zero point and full point adjustment

As shown in the figure below, zero is adjusted by rotating(Z)Adjust to full(S)Two potentiometers are used to adjust the zero and full points.

Attention: The transmitter has been adjusted to a better range, accuracy, and linearity according to user needs before leaving the factory, and generally does not require on-site adjustment.
