D21 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 -40-135°C with high accuracy and high stability in
measurement. Its anti-overload capacity is up to 100 times of the
range, competely solved poor overload of small range of other
sensor. In addition to general range 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 manufacture of high performance industrial control
pressure transmitter and harsh environment pressure measurement.
WD21 series pressure sensors are solution for below applications:
*Pressure measurement of gas, vapor or liquid in various areas;
*Liquid level, volume or mass measurement;
*Intehrated in variety of user-defined solutions.
Features:
*Dry ceramic capacitive pressure sensor;
*Robust ceramic capacitive sensitive;
*Excellent performance in corrosion and abrasion application;
*Suitable for pollution and corrosive environment;
*Flat large round diaphragm, easy installation;
*Superb positive and negative gauge pressure function;
*Highest overload up to 100 times of range;
*Rapid response, no hysteresis;
*Wide operation temperature range -40-135°C;
*Sensor specific signal conditioning;
*0.5-4.5V voltage and IIC digital output;
*Accurate, stable and reliable;
