W21 Ceramic Capacitive Pressure Sensor
W21 series is dry ceramic capacitive pressure sensor made by special technology processed ceramic. Ceramic is a well-known material with long-range elasticity, anti-corrosion, wear & shock resistance and anti-vibration. Thermal stability of the ceramic makes its operating temperature range up to -40 to 135 ºC with high accuracy and high stability in measurement. 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, such as: ± 10kPa, ± 1MPa and so on. With high output and wide range, W21 ceramic capacitive sensor is especially suitable for manufacturing of high-performance industrial control pressure transmitter and harsh environment pressure measurement.
