Công tắc chênh áp J21K-150 UE - United Electric Controls J21K Series Differential Pressure Switch

The J21K Series is simple to install and operate for alarm, safety and emergency shutdown applications requiring a higher switch sensitivity. It monitors the difference between two system pressures or vacuum using sealed, opposing bellows sensors. As an electromechanical switch, it can safely operate independently of the control system and switch reliably when called upon, free from potential communication errors or cyber concerns.

Typical applications that utilize the J21K Series include proof of flow, filter monitoring, vacuum pumps, chillers, and compressors.
