Overview

The set value or switching point of the air differential pressure switch can be adjusted on-site by simply using the adjustment knob and the built-in calibrated visual scale. This switch is equipped with a clear cover that not only protects the adjustment knob scale from changes, but also provides IP54 protection. Repeated switch experiments ensure the long service life of the switch.
