Dwyer Magnehelic Differential Pressure Gauge

Dwyer Magnehelic low differential pressure is an industry standard gauge for low differential pressure monitoring.
Model: 2000-60PA (range 0-60Pa) is a very common supply for clean room pressure monitoring and also common in LEV (e.g. fume cupboard) applications.  In addition, new in 2020, Dwyer have added a new 0-30Pa model for increased accuracy and resolution at very low pressures.


Higher Magnehelic ranges such as 2000-250PA and 2000-500PA are common place in HEPA filter monitoring.
Accompanied with our in-house green/red (go/no-go) zoning, these are ideal for monitoring of filter puncture and blocking.  With an exterior finish tested against a 168hr salt spray test, Dwyer Magnehelic DP gauges are also often found in offshore applications.


The Dwyer Magnehelic low differential pressure gauge offers a non contact solution of measurement.  A magnet drives a helix, in turn rotating the dial pointer to show an accurate indication of differential pressure measurement.  With this non contact technology, the Dwyer Magnehelic offers a stable and repeatable measurement of differential pressure.  For an instrument with a 4-20mA transmitter output consider the Dwyer Series DH3 Digihelic Differential Pressure Controller or with 2x relay contacts consider the Dwyer Photohelic A3000 Switchgauge (230V mains powered) or Dwyer Photohelic 3000MR Switchgauge (24V).


Dwyer Magnehelic® Ranges available include… (custom ranges also available)

0…30Pa, 0…60Pa, 0…125Pa, 0…250Pa, 0…500Pa, 0…1000Pa (1KPA)
0…2KPA, 0…3KPA, 0…5KPA, 0…10KPA, 0…30KPA


Fluidic hold several Pa (pascal) ranges ex/stock.
Also available in “WG, mmWG, mbar and other customer ranges (including airflow) via Fluidic’s in house rescaling service.


Fluidic offer multiple ‘Magnehelic Solution’ services, including green/red (go/no-go) overlay zoning, calibration and instrumentation assemblies.  Our ‘Magbo’ Enclosure mounts offer the Magnehelic gauge in stainless steel or polycarbonate instrument enclosures, supplied with professionally finished traffolyte tagging.  DP terminations can be back, bottom or top mounted to suit. Doors can be hinged as required.  Our instrumentation panels also offer the Magnehelic DP gauge mounted to a 5 valve, stainless steel back plate.  This is ideal for calibration and maintenance checking, which can be carried out without having to physically remove the Magnehelic gauge from service.
