Working Principle of magnet-helix indicating mechanism
When pressure in applied to both sides of the diaphragm
in operation, any difference in pressure causes the
diaphragm, the spring that the diaphragm is linked to,
and the magnet attached to the spring to move.
the movement of the magnet forces the magnet helix to turn in order to maintain the gap, and the
pointer fixed to the helix turns with it.
APPLICATIONS:
The 1650 series DP gauges are designed to measure positive, negative (vacuum) or differential pressure
of low air and non-corrosive gases with a full span accuracy of 2% at a competitive price. They are
widely used for filter condition checks, HVAC control, and the measurement of fan an blower pressures,
air velocity, and pressure drop across orifice plates applications, as well as other applications in the
pharmaceutical and semiconductor manufacturing industry.
