Description

Micro Magnetic Differential Pressure Gauges are designed to measure the difference in pressure between two points (High & Low) in a system where static pressure is very high.

The difference in pressure causes the sensor assembly to move in proportion to the change against a range spring. A rotary magnet located in a separate body cavity and isolated from the acting pressures, is rotated by magnetic coupling as per the linear movement of the sensor assembly. A pointer attached to the rotary magnet indicates differential pressure on the dial. Switch: Reed switches are located adjacent to the pressure chamber and are activated by the magnetic field of the sensor assembly.
