- Ideal to monitor filter conditions, determine obstructions in process lines, heat exchangers, pumps etc.
- Zero fluid migration between high and low inputs.
- Adjustable reed contact switching optional.
- Available as switch only
High and low pressures are separated by a sensor assembly consisting of a magnet, diaphragm and a range spring. 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
