Background
An instrument for measuring fluid pressure. The measured pressure is typically compared to some reference pressure (e.g., atmospheric or other given pressure) and thus a relative or differential pressure is measured.
According to different working principles, the device can be divided into 3 forms of a liquid column type, an elastic type and a sensor type. Liquid column type pressure gauges such as U-tube pressure gauges and calandria pressure gauges convert pressure signals into liquid column height signals according to the hydrostatic principle, and water, alcohol or mercury is usually used as a pressure measuring working medium. The elastic type such as a bourdon tube pressure gauge converts a pressure signal into a mechanical deformation amount of the elastic element, and outputs the signal in a pointer deflection mode. Such pressure gauges are used in industrial systems. The pressure sensor converts a pressure signal into an electric signal, such as a strain gauge, changes resistance by deformation of an elastic element, and utilizes a piezoelectric effect.
