Products Description
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.
It 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, etc.Meanwhile, it's also used for air gas ratio and automatic valve control in the combustion process well a monitor of blood pressure and respiratory pressure in health care equipment.
Specification
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
multiple ranges are optional, minimum 0 ~ 30Pa to maximum 0 ~ 210KPa
2 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
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.
