107 Low Differential Pressure Switch

Brand: SOR Inc

SOR 107 low differential pressure switches are robust, field-mounted instruments designed for the process industries. 

These instruments accurately read very low pressures by utilizing a diaphragm with a large sensing area. 

The switching element is SPDT. 

An external Set Point adjustment with visual indication is standard, allowing for simplified calibration of the switch.
