The UE J21K differential pressure switch maintains the difference between two system pressures or vacuums, senses excessive flow deviation, or verifies that a filter is clogged. It is designed with two separate opposing sensors that are connected by a rod to actuate the snap switch.
J21K's rugged design, with epoxy coated enclosure and sealed metal bellows, lends itself to exacting applications. Widely used in chiller and compressor applications, the J21K can be used for filter status monitoring and proof of flow.
