107 Low Differential Pressure Switch
Brand: SOR IncSOR 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.
