107 Low Range – Weatherproof Differential Pressure Switch

Designed primarily for air and clean gas applications for low pressures, the weatherproof 107 low-range differential pressure switch accurately reads very low pressures in locations requiring protection from the elements.

Its diaphragm has a large sensing area and is the perfect choice for pressurized (clean) room applications because it measures the difference between one room and another (air ducts) and lets you know if an air filter is clogged.

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