Differential Pressure Gauges

The series A2 Differential Pressure Gauges are designed to measure positive, negative, 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 and blower pressures, air velocity, and pressure drop across orifice plates applications, as well as other applications in the pharmaceutical and semiconductor manufacturing industry.

When pressure is 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 magnetic helix to turn in order to maintain the gap, and the pointer fixed to the helix turns with it.

Magnet-helix indicating mechanism ideal for low Differential Pressure measurement:
• Surface mounting with 2-5/8″ hole
• Accuracy 5% of Full Scale
• Easy to read through lucid lens
• High static pressure to 30 PSI
• Good quality and low cost

Air Filter Gauge Kit (model 301-P):
