Performance principle
heat conduction vacuum gauge and a diffused silicon piezoresistive vacuum gauge; in general, the resistance (Pirani) vacuum gauge ranges from 1.0 × 104Pa to Atmospheric pressure, the measured value is easy to drift and unstable. The piezoresistive vacuum gauge has high accuracy and stability in this measuring range, but the piezoresistive vacuum gauge cannot measure the vacuum higher than 1.0 × 103 Pa. Therefore, the two are combined to achieve In order to measure vacuum with a wide range and high accuracy, the two sensors are always in a strong state of work.
