Work with simple and frictionless gauge movements with this 115 V AC Magnehelic differential pressure gauge that quickly indicates air or noncorrosive gas pressures, either positive, negative (vacuum), or differential. In addition, this gauge resists shock, vibration, and over-pressures and is weatherproof to IP67.

Features
Overpressure protection
Blowout plug is comprised of a rubber plug on the rear which functions as a relief valve by unseating and venting the gauge interior when over pressure reaches approximately 25 psig (1.7 bar). To provide a free path for pressure relief, there are four spacer pads which maintain 0.023" clearance when gauge is surface mounted. Do not obstruct the gap created by these pads. The blowout plug is not used on models above 180" of water pressure, medium or high pressure models, or on gauges which require an elastomer other than silicone for the diaphragm. The blowout plug should not be used as a system overpressure control. High supply pressures may still cause the gauge to fail due to over pressurization, resulting in property damage or serious injury. Good engineering practices should be utilized to prevent your system from exceeding the ratings of any component.
