Differential pressure switch J21K series

Product Introduction

The US UE differential pressure switch J21K series is used to detect the pressure difference between two systems or vacuum devices, or to sense excessive flow deviation, or to verify whether a filter is clogged. The robust design of the J21K series differential pressure switch - coated with epoxy resin and sealed with metal bellows - is suitable for various extreme applications. Widely used in the refrigeration (cooler) and compressor industries, the UE differential pressure switch J21K series can be used to monitor the status and flow of filters.
