Low Cost Water Air Pressure Sensor with I2C 0.5-4.5V 0-10V 4-20mA Output

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.

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 isthe 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.

>> 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;

Technical Parameters

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

Dry ceramic capacitive pressure sensor has no liquid transfer. Process pressure acts directly on the front surface of the ceramic diaphragm. Capacitance change between the substrate electrode and the diaphragm electrode is proportional to the pressure value. The initial value of capacitance is fine adjusted by laser to be coincident as the proportion. When overloading, the film clings to the ceramic substrate without damage. 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.

Capacitive pressure sensor has excellent temperature stability; working with ASIC dedicated signal conditioning circuit, it can be temperature compensased in -40 ~ 125 ℃. The dual capacitance structure designed internally with main capacitor (Co) and reference capacitor (Cref) can offset most temperature and non-linearity errors.
