Kind of pressure sensor range, its performance is also quite different, how to choose a more suitable sensor pressure sensor price, so that the economic and rational use. 1. Rated pressure range Rated pressure range to meet the standard value of pressure range. That is, between the highest and lowest temperature and pressure sensors, sensor output comply with the operating characteristics of the pressure range. In practical applications the pressure measured by the sensor within the range. 2. The maximum pressure range Maximum pressure range is the sensor can long withstand the maximum pressure miniature pressure sensor, and does not cause permanent changes in output characteristics. Especially semiconductor pressure sensor, to improve the linearity and temperature characteristics are generally rated pressure range is greatly reduced. Therefore, even when used continuously for more than the rated pressure will not be damaged. The maximum pressure is generally linear range of 2-3 times the rated pressure of the linear range of the sensor means that the range of the maximum value of the output proportional to the input. In theory, in principle within the scope of the pressure sensor, the sensitivity is constant. The wider linear range of the sensor, the greater its range, and can guarantee a certain accuracy. When selecting sensors, sensor type When determining whether a first look at its range to meet the requirements. But in fact, any sensor can not guarantee linear, its linearity is relative. When the required measurement accuracy is relatively low, in a certain range, can be non-linear error smaller sensor approximated as linear, this measure will bring great convenience.
