Pressure Gauge LFB

LEFOO pressure gauge LFB is a kind of elastic strain gauge that consists of magnetic spiral movement and rubber diaphragm as the sensitive element to measure the pressure. It displays the pressure of tested gas by pointer and scale, the pressure gauges are capable for positive pressure type, negative pressure type or differential pressure type.

The 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 from 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.


Features of LEFOO Differential Pressure Gauge LFB

*3 types of measurement options, Positive pressure gauge, Negative Pressure gauge, Differential Pressure Gauge.


*Magnetic link drive mechanism eliminates friction caused by gear drive fundamentally


*No necessity to fill with liquid


*The motion of the pointer without inertia or drift


*No hysteresis


*Excellent anti-vibration and anti-shaking performance


*Positional pressure can be measured


Application of LEFOO Differential Pressure Gauge and Pressure Gauge

The differential pressure gauge is optimal for the application of air gas ratio and automatic valve control in the combustion process well a monitor of blood pressure and respiratory pressure in health care equipment. The pressure gauge LFB is widely used for measuring fan&blower pressure, filter resistance, wind speed, furnace pressure, orifice differential pressure, air bubble water level, liquid amplifier or hydraulic system pressure,  Dust and waste gas treatment equipment, etc.
