The main performance parameters of the pressure sensor

What are the main performance parameters of pressure sensors? There are many types of pressure sensors, and there are differences in performance. However, we must pay attention to the choices. How can we be economical and reasonable? The following is the world of instrumentation. The introduction of the net.

1. Rated pressure range The rated pressure range is a pressure range that satisfies the standards. That is, between the highest and lowest temperatures, the sensor outputs a pressure range that meets the specified operating characteristics. In practice, the pressure measured by the sensor is within this range.

2. Maximum pressure range The maximum pressure range is the maximum pressure that the sensor can withstand for long periods of time without causing permanent changes in the output characteristics. In particular, semiconductor pressure sensors generally reduce the rated pressure range significantly in order to improve the linearity and temperature characteristics. Therefore, it will not be damaged even if it is used continuously above the rated pressure. The general maximum pressure is 2-3 times the highest rated pressure.

3. Damage to Pressure Damage to pressure is the maximum pressure that can be machined on the sensor without damaging the sensor element or the sensor housing.

4. Linearity - The linearity of the main performance parameter of the pressure sensor is the maximum deviation of the linear relationship between the output of the sensor and the pressure within the working pressure range.

5. The pressure hysteresis is the difference between the sensor output when the minimum working pressure and the maximum working pressure approach a certain pressure at room temperature and within the working pressure range.

6. Temperature range The pressure sensor temperature range is divided into compensation temperature range and operating temperature range. The compensation temperature range is due to the temperature compensation applied and the accuracy within the temperature range of the rated range. The operating temperature range is a temperature range that ensures that the pressure sensor can operate normally.
