China Low Cost High Accuracy Electronic Micro Compressed Air
Pressure Sensor
Description
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.
