Introduction

    

    WNK80MA is a series of high performance compact pressure transmitter by using ASIC signal conditioning chip and dry ceramic capacitive pressure sensor. It has features of anti-corrosion, anti-wear, shock resistance and vibration resistance. Its anti-overload capacity is up to 100 times of the range, completely solved poor overload in small range of other sensors.  In addition to general ranges of normal sensors, its most outstanding characteristic is the positive and negative gauge pressure function. With high output and wide range, WNK80MA is especially suitable for manufacturing of high-performance industrial control pressure transmitter and harsh environment pressure measurement.


 

Applications:

  • Pressure measurement of gas, vapor or liquid in various areas;

  • Liquid level, volume or mass measurement;

  • Integrated in a variety of user-defined solutions;

  • Smart water and gas management, smart fire controling, automotive electronics controlling, air compressor, HVAC, pump, valve and etc;


 

Product Features:

  • Specific high performance ASIC conditioning circuit;

  • Dry ceramic capacitive pressure sensor;

  • Robust ceramic capacitive sensitive membrane;

  • Excellent anti-corrosive and anti-wear performance;

  • Suitable for pollution and corrosive environment;

  • Various electrical connectors optional;

  • Rapid response, no hysteresis;

  • Wide operating temperature range -40~135℃;

  • Anti-icing;

  • 0.5…4.5V and 4…20mA analog output or I2C and SPI digital output;

  • Accurate, stable and reliable;
