Vacuum pressure sensor application

Vacuum Pressure Sensor Measurement Overview
Vacuum pressure sensor is a kind of pressure sensor commonly used in industrial practice. Vacuum pressure sensor is a piezoresistive pressure sensor, which is widely used in various industrial self-control situations, affecting oil pipelines, water conservancy and hydropower, railway transportation, intelligent construction, production control, and aerospace. , military, petrochemical, oil wells, electricity, ships, machine tools, pipeline air supply, vacuum equipment and other mega industries.
