1. Metal film pressure sensor

Metal thin film pressure sensor is a complete structure formed by chemical or physical methods on ceramic substrate, and then induced current is introduced. It has the characteristics of high sensitivity, fast response and stable output signal, and is widely used in situations with large temperature change, strong mechanical vibration and high pressure measurement requirements.

2. Oscillating crystal pressure sensor

Oscillating crystal pressure sensor uses oscillating crystal to measure pressure. When subjected to external pressure, the crystal will be slightly deformed, and the deformation will affect the frequency of the device, thus measuring the pressure value. This sensor has the advantages of fast response and no crosstalk, and is suitable for high-pressure dynamic measurement and pressure measurement of liquid and gaseous media.

3.*** Vibration pressure sensor

* * * Vibrating pressure sensor is based on the principle of * * * vibration, and uses the relationship between natural frequency and pressure to measure pressure. It has the advantages of simple manufacturing process, compact structure, small volume and fast response, and is suitable for pressure measurement in the middle and low range.

4. Piezoresistive pressure sensor

Piezoresistive pressure sensor uses the deformation characteristics of thin film resistive materials under external force to measure pressure. When the external pressure increases, the thin film material inside the sensor will be slightly deformed, thus changing the resistance value of the material. This kind of sensor has high precision and relatively low price, and is widely used in all walks of life.

5. Differential pressure sensor

The differential pressure sensor exposes two measuring chambers to different pressures, and calculates the pressure by measuring the pressure difference of different chambers. This kind of sensor is often used to measure parameters such as flow, liquid level and volume. It has the advantages of high precision, good stability and strong anti-interference ability. ? Different types? Precision tube pressure sensor? According to different applications and requirements, it provides a choice. By understanding these types and their characteristics, we can better choose the most suitable sensor and ensure that it can achieve high precision, high reliability and long-term stability of pressure measurement.
