Low Power Consumption 0.5-4.5V 0-5V I2C Water Pressure Sensor for Agriculture Irrigation



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 addtion 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.
