Differential pressure gage, range 0-25" w.c., minor divisions .50.
Indicate Positive, Negative or Differential, Accurate within 2%
Dwyer 2025 Magnehelic® gage helps to quickly indicate low pressure of non-corrosive gases or air, including differential, negative (as vacuum) and positive. The device possesses special design and construction that withstands vibration and shock, moreover, this cost-effective item resists over-pressures.
Scope of use:
- monitoring of filter;
- air velocity (with Pitot tube);
- monitoring blower pressure;
- indication of fan pressure;
- duct, room or building pressures;
- indication of clean room positive pressure.
This industry standard is also used in medical equipment to read respiratory and blood pressure.
Construction characteristics:
- can be flush-mounted in panels due to a flange provided by bezel and specific assembly type (for pointer shaft, helix or helix bearings);
- provides clear visibility and easy reading of measurements by virtue of its scale and clear face made of plastic, which resists breakage;
- rigidly mounted pointer possesses a red tip and has rubber stops preventing over-travels;
- plastic cover accommodates the "0" adjustment screw providing the user with an easy access;
- jeweled bearings provide free turning of helix (it moves without mechanical linkage due to Samarium Cobalt magnet), thus, accurate moving of the pointer across the scale;
- calibrated range spring moves with a small amplitude, reacting on diaphragm thus provides consistency and long service.
The versatile array of benefits comprises also the silicone rubber diaphragm, which is fixed in position with a sealing plate, retaining rings and is supported by rear and front plates. The Iridite treatment of the die cast aluminum case provides superior resistance to corrosion.
The Dwyer 2025 gage is reliable for it possesses a specific blowout rubber plug which relieves over-pressures – it unseats and vents the gage interior at 25 psig.
Warning:
- do not obstruct the gaps created by spacer pads which provide the tool with pressure relief path.
- do not use this gage as a system for controlling over pressures for constant over pressures may still cause damages.
The qualitative product is created to perform flawlessly and to increase your level of professionalism.
