Designed primarily for air and clean gas applications for low pressures, the hermetically sealed low range differential pressure switch accurately reads very low pressures in hazardous locations requiring protection. The 107EL employs a diaphragm with 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.
