Choosing a Deville Magnehelic differential pressure gauge ensures high precision at full scale and offers up to 81 range options to precisely meet your requirements. This differential pressure gauge uses the simple and frictionless Magnehelic moving parts from Weil, Germany, which can quickly measure the micro pressure of air or non corrosive gases - positive pressure, negative pressure (vacuum), or differential pressure. Its design is impact resistant, shock resistant, and has overload protection. It does not have problems with pressure gauge liquid evaporation or freezing, nor does it cause poisoning or level issues, and its price is also very low.

Magnehelic is widely used in industry to measure the pressure of fans and blowers, filter resistance, wind speed, furnace ventilation, pressure drop caused by orifice plates, liquid level of foaming systems, and pressure of boosters or hydraulic systems. It can also detect gas air ratio control and automatic control valves, as well as monitor blood and respiratory pressure on medical equipment.
