Mechanical pressure switch LF52

differentialthreadedfor air

This adjustable differential pressure switch LF52 is eveloped for sparingly using in different differential value requirements. It is widely applied for detecting the differential of water filter, pump, heat exchanger, chillers and its col unitsWhen the water flowing(differential) decrease or increase to the setting point, there will be an alarm or cut off output signal for the self-controlling system. It's also available forindicating the status of pump or water filter. Double differential settings pressure switch can take the replacement of the vane flow switch and avoid changing the vane flow switch from chillers each year. A single set point is a high/low limit that controls the differential pressure between the front and rear ends of a section of pipeline. The double set point is to control the high and low limit of the pressure difference between the front and rear ends of a pipeline, and can also control the high/low limit of the pressure difference between the front and rear ends of the two pipelines.
