product overview Product overview

The pressure sensing structure of the LPS-S2 series diaphragm pressure switch adopts a fully welded stainless steel diaphragm. The entire design is simple and easy to use, with few fault points, and can effectively prevent liquid leakage and misoperation. It has an adjustable switching difference function and can be used for pressure range control and pressure interval alarm; Widely used in various industries such as petroleum, chemical, metallurgical, power, sugar, pharmaceutical, etc. that require pressure control.

measuring principle principle

Diaphragm pressure switch is a mechanical pressure switch that uses the mechanical deformation of the diaphragm to achieve the function of controlling contact closure and disconnection. When the pressure of the measuring medium changes, the diaphragm will produce corresponding displacement. The displacement of the diaphragm is transmitted to the micro switch through the transmission component. When the displacement stroke reaches the set value, the micro switch will be pushed, causing the contacts of the micro switch to close or open as a state variable. Adjustable pressure switches can control pressure within a fixed value or range by adjusting the stroke relationship between transmission components and micro switch contacts, in order to achieve control objectives.
