Is the pressure gauge also a pressure sensor?
Yes, and displayed through the dial
A pressure meter that is converted to other signals and is called a pressure sensor. The pressure gauge is just a measuring and displaying instrument.
Pressure meter: an instrument that measures and indicates higher than the ambient pressure by means of an elastic element as a sensitive element. The application of pressure gauges is very common, and it covers almost all industrial processes and scientific research fields. In the heat pipe network, oil and gas transmission, water supply system, vehicle repair and maintenance shop, and other fields can be seen everywhere. Especially in the control and measurement process, because the elastic sensitive element of mechanical pressure gauge has the characteristics of high mechanical strength and convenient production, the mechanical pressure gauge is widely usedThe sensor is a detection device, can feel the measured information, and can feel the information, according to the law must transform into electrical signals or other information in the form of output required to meet the information transmission, processing, storage, display, record and control requirements. It is the first step of automatic detection and automatic control.By definition, a pressure gauge is a type of sensor that is sensitive to changes in a physical quantity.
