Basic information :

The J21K differential pressure switch monitors the difference between two system pressures or vacuums and senses excessive flow deviation, or verifies that a filter is clogged.

The J21K's rugged design - with epoxy coated enclosure and sealed metal bellows - lends itself to exacting applications.Widely used in refrigeration (chiller) and compressor applications, the J21K can be used for filter status monitoring and proof of flow
