Differential Pressure Switches
General description of the product
Differential pressure switches are used in applications to signal that a predetermined pressure difference has been reached as a result of widening or narrowing difference between the two points within piping systems or machinery.
A conventional differential pressure switch is generally a simple electro-mechanical device that operates on the basic principles of lever and opposing forces connected with the diaphragm, metallic or elastomeric elements deformable due to pressure acting on the elements. The pressure difference creates a force which then overcomes that of a pre-tensioned spring and in the process, moves a balancing arm or mechanism to effect the minimal movement required to actuate the micro-switch of the switch.
Electronic differential pressure switches which are microprocessor-controlled differential pressure measurement devices with pressure sensors, such as piezo-electric pressure sensor, potentiometric pressure sensor, differential capacitance, etc. are also available.
