Dongfang Wanhe WH131-PM pressure sensor

application

Shield boring machine,brick making machinery,etc.

product description

The WH131-PM transmitter has a built-in anti-interference amplification circuit,which is suitable for signal output under complex conditions; the product adopts spherical sealing,which is easy to install and use,and is suitable for various exploration and working conditions.

It is widely used in drilling equipment in the petroleum industry,especially imported fracturing trucks,cementing trucks,etc. for high-pressure measurement. It can replace various imported pressure gauges such as Vitron,Dowell,Stevenson-Stewart,and Beejie from the United States. Cracking car sensor.

Strain-type high-pressure pressure sensor is a new product integrating foreign advanced technology and domestic sensor manufacturing technology.

This sensor uses imported high-precision large resistance strain gauges and unique domestic variable thickness diaphragm technology. Its measurement range can reach 120Mpa,and has high response,high precision,solid structure,corrosion resistance,vibration resistance,high performance and price ratio,etc. Features
