Differential Pressure Switch Model J21K
316L SS, Brass or Phosphor Bronze Bellows, Adjustable Ranges 30” Hg to 90 PSID
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.
