Pressure Switch
Pressure switch is a device designed to monitor a process pressure and provide an output when a set pressure (setpoint) is reached. Pressure switches have different designs with different sensing elements.
YK series Pressure Switch
YK series pressure switch does this by applying the process pressure to a diaphragm (sensing element) to generate a force which is compared to that of a pre-compressed range spring. The movement of the diaphragm is used to actuate one or more micro switch contacts to indicate an alarm or initiate a control action. YK pressure switch can be used in home and commercial application for low pressure or over pressure protection, for example, refrigeration, air compressor, power transmission etc.
