| >> 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.
