Differential Pressure Gauge

Lefoo develops components for several applications, considering the main demands of the world market. Among these items are pressure gauges.

The LFB differential pressure gauge is a type of elastic pressure gauge that uses simple, frictionless magnetic spiral movements and a rubber diaphragm as a

sensitive element to measure pressure. Indicates the pressure of the gas tested by the needle, regardless of positive, negative or differential pressure.

This design has the function of shock resistance, anti-vibration and over-pressure. And it is not necessary to fill with liquid, to avoid problems of gasification, freezing or smell.

It is widely used to measure fan and fan pressure, filter resistance, wind speed, oven pressure, differential orifice pressure, air bubble water level, liquid amplifier or hydraulic system pressure, etc.

Meanwhile, it is also used for the gas-to-air ratio and automatic control of valves in the combustion process, as well as a blood pressure and respiratory pressure monitor in healthcare equipment.

The magnetic link drive mechanism eliminates the friction caused by the gear transmission fundamentally

No need to fill with liquid

Pointer movement without inertia or deviation

Without hysteresis

Excellent anti-vibration and anti-agitation performance

Positional pressure can be measured

various ranges are optional, minimum 0 ~ 30Pa to maximum 0 ~ 210KPa

2 sets of pressure holes (side, rear) + 3 mounting modes = free and flexible application.

Excellent accuracy, reasonable price.

Ambient temperature -70 ~ 60 ° C

Pressure -68 ~ 103KPa
