Differential Pressure Switch
The J21K Series differential pressure switch monitors the difference between two system pressures or vacuums. It senses excessive flow deviation or verifies that a filter is clogged.
The J21K Series switch’s rugged design – with epoxy-coated enclosure and sealed metal bellows – lends itself to exacting applications. Widely found in refrigeration (chiller) and compressor applications, the J21K Series differential pressure switch is used for filter status monitoring and proof of flow.
