Function of a differential pressure gauge
The media chambers of a differential pressure gauge are separated from each other by the pressure element. If the two pressures being measured are the same, there is no movement through the pressure element and no pressure is indicated. As soon as the two measured values are different to each other, thus one of the pressures is higher or lower, then a differential pressure will be indicated. The transmission of the pressure element displacement and the indication of the pressure is achieved via a mechanical movement.

LFB differential pressure gauge is a kind of elastic pressure gauge which makes use of simple, non-friction magnetic spiral movement and rubber diaphragm as the sensitive element to measure the pressure. It indicates the pressure of tested gas by pointer, no matter it’s positive, negative or differential pressure.

This design has the function of shock resistance, anti-shaking and overpressure proof. And it’s no necessity to fill with liquid, to avoid problem of gasification, freezing or smell.

Industries

LFB series is widely used for measuring the fans or blowers pressure, filter resistant, wind speed, furnace gas pressure, Orifice pressure difference, bubble level and hydraulic system pressure. It is also applied to regulate the air-gas combustion ratio and automatic valve or detecting the breathing, and blood pressure in medical equipment. There are some more applications like microelectronics, aviation and space, environmental protection project, biological engineering, intelligent building, HVAC, food and beverage and precision electronic processing
