J21K Series Overview
Differential Pressure
Switch
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.
