An electrical contact pressure gauge is an instrument used to measure the pressure of liquids or gases. It converts pressure signals into electrical signals through changes in the state between a sensing circuit and mechanical contacts. Compared to conventional pressure gauges, electrical contact pressure gauges offer higher accuracy and reliability, and are widely used in many industrial fields.
Differences between Electrical Contact Pressure Gauges and Conventional Pressure Gauges: Electrical contact pressure gauges and conventional pressure gauges differ in their working principles and characteristics.
Conventional pressure gauges sense pressure through the deformation of a mechanical spring or diaphragm and indicate the pressure value via a pointer. They are typically suitable for applications requiring lower accuracy, such as general industrial measurements.
Electrical contact pressure gauges, on the other hand, use electrical signal transmission. When the pressure changes, the contacts inside the electrical contacts open or close, thereby altering the current state in the circuit. This change can be sensed and processed by external electronic equipment. Electrical contact pressure gauges are commonly used for automatic pressure monitoring, control, and recording, offering higher accuracy and better reliability.
In addition, electric contact pressure gauges can also provide remote transmission and automated control functions, making pressure data acquisition and processing more convenient and flexible.
