Consists of magnetic spiral movement and a rubber diaphragm as the sensitive element to measure the pressure. LEFOO differential pressure gauge LFB-1 is a kind of elastic strain gauge that displays the pressures of tested gas by pointer and scale. The positive pressure type, negative pressure type, or differential pressure type are optional.
multiple ranges are optional, minimum 0 ~ 30Pa to maximum 0 ~ 210KPa
two sets of pressure ports (side, back) + 3 mounting modes = free and flexible application.
Excellent accuracy, reasonable price.
Environment temperature -70 ~ 60°C
Rated pressure -68 ~ 103KPa
DP gauge, Dwyer Magnehelic replace
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 pressure measurements 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 transfer into a mechanical movement.
*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 measurement is available
The differential pressure gauge is optimal for the application of air-gas ratio and automatic valve control in the combustion process well as 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.
