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.
