4~20mA SPI I²C 0-5V Compact Pressure Transducer

Details

Introduction

    Based on technology of A10 series, WNK80MA is low cost and high performance oil filled pressure transmitter. It is with completely welded stainless housing and installed ASIC to realize digits amplification, linearity and temperature compensation. Circuit design is highly integrated meeting lastest CE on electromagnetic interference standard.

  The WNK80MA transmitter is in small size with various optional thread connection and wiring method; output standard 4~20mA or 0.5-4.5V, 0-5V etc industrial signal. We could also produce varied special structure and output products as per customers requirements.

 

Applications:

Hydraulic and pneumatic control systems

Energy and water treatment systems

Level measurement

Auto detection system

Vessel and aviation fields

 

Product Features:

Piezoresistive oil-filled chip

Suitable for small or medium pressure (0-100Kpa…7Mpa)
