100mm Series Electric Contact Auto-controlling Pressure Gauge

100mm Series Electric Contact Auto-controlling Pressure Gauge For Gas/Liquid

Basic Info.

Construction

Pressure Sensing Element: At the core of the gauge is a precision - made pressure - sensing element, usually a Bourdon tube or a diaphragm. This element deforms in response to changes in pressure, and the deformation is translated into a mechanical movement.

Indicator and Scale: The mechanical movement of the pressure - sensing element is transmitted to an indicator needle, which moves along a calibrated scale to show the pressure value. The scale is clearly marked to provide easy - to - read pressure readings.

Electric Contact Assembly: The electric contact assembly consists of adjustable contact points. These points can be set according to the required pressure limits, and they are electrically connected to the external control circuit.

B. Working Principle

Pressure Detection: When pressure is applied to the pressure - sensing element, it undergoes deformation. For example, in a Bourdon - tube - based gauge, the curved tube straightens slightly as pressure increases.

Mechanical Transmission: The deformation of the pressure - sensing element is transferred through a series of mechanical linkages to the indicator needle and the electric contact mechanism.

Electric Signal Generation: When the pressure reaches the pre - set limit, the movement of the contact points closes or opens the electrical circuit, generating an electric signal for further control actions.
