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.
Specification of Differential Pressure Gauge LFB
two sets of pressure ports (side, back) + 3 mounting modes = free and flexible application.
Excellent accuracy, reasonable price.
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.
Features of 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 measurement is available
