dwyer 2000-125pa magnehelic differential pressure gauge dwyer 2000-125pa magnehelic, differential pressure gauge, 0/125pa, vs precision litho-printed scale is accurate and easy to read. red tipped pointer of heat treated aluminum tubing is easy to see. It is rigidly mounted on the helix shaft. pointer stops of molded rubber prevent pointer over-travel without damage. "wishbone" assembly provides mounting for helix, helix bearings and pointer shaft. jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix. Motion damped with high viscosity silicone fluid. zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness. helix is precision made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the magnetic field to move the pointer across the scale. samarium cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages. calibrated range spring is flat spring steel. Small amplitude of motion assures consistency and long life. It reacts to pressure on diaphragm. Live length adjustable for calibration. silicone rubber diaphragm with integrally molded o-ring is supported by front and rear plates. It is locked and sealed in position with a sealing plate and retaining ring. Diaphragm motion is restricted to prevent damage due to overpressures. die cast aluminum case is precision made and iridite-dipped to withstand 168 hour salt spray corrosion test. Exterior finished in baked dark gray hammerloid. One case size is used for all standard pressure options, and for both surface and flush mounting. what's included with the dwyer 2000-125pa dwyer 2000-125pa magnehelic differential pressure gauge (0-125 pa), vertical scale

Generally Pressure Gauges and Differential Pressure Gauges are provided with Micrometer type Pointer, by which zero can be adjusted after opening the bezel & glass. However for gauges with Liquid filled Case, this arrangement is practically not suitable, since the filling liquid has to be drained before opening the bezel & glass. After doing the zero adjustment, the Bezel & Glass has to be re-assembled and again the case has to be filled with Liquid. In order to overcome this difficulty, general instruments Consortium has developed a unqiue design if external zero adjustment. By this arrangement, zero can be adjusted without draining the Glycerine, without opening the Bezel, without removing the glass & without touching the pointer, just by rotating a knob provided outside the gauge.

These gauges are intended for measuring the pressure differential existing across two media or two parts of a system. The pressure element separates the two pressurized media, and deflects proportional to the difference in pressures between the media, irrespective of the absolute pressures applied. This deflection is converted into the rotation of a concentric pointer on a dial, similar to regular pressure gauges. The absolute value of either of the pressures is not usually indicated
