Low current Cheap Price Dry Ceramic Air Pressure Sensor
W21 series is dry ceramic capacitive pressure sensor made by special technology processed ceramic.its operating temperature range up to -40 to 135 ℃ with high accuracy and high stability in measurement.
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.
| >> Main Features |
1. Robust ceramic capacitive sensitive diaphragm;
2. Excellent performance in corrosion and abrasion
application;
3. Normal pressure sensor diameter suitable for compact
pressure transducer;
4. Suitable for pollution and corrosive environment;
5. Superb positive and negative gauge pressure function;
6. Highest overload up to 100 times of pressure range;
7. Rapid response, no hysteresis;
8. Wide operating temperature range -40~135℃;
9. 0.5 ... 4.5V, I²C , SPI & 4~20mA output optional;
Application:
1. Pressure measurement of gas, vapor or liquid in various
areas;
2. Liquid level, volume or mass measurement;
3. Integrated in a variety of user-defined solutions.
| >> Appearance and dimensions |
| >> Working principle |
When pressure resumes normal, its performance is not affected. W21 dry ceramic capacitive pressure sensor completely solved poor overload in low range shortcomings of diffused silicon sensor, and has been new generation products if diffused silicon sensor. The sensor has excellent temperature and time stability, and can contact with most media directly.
As no liquid transmission and no liquid filling in ceramic capacitive sensor, there will be no production process pollution. So it can be widely applied in food, medicine, refrigeration, automotive and etc. In addition to dry ceramic capacitive diaphragm, installation direction will not have any influence. Pressure transmitter with it as sensitive component can be widely used various pressure measurement situations.
