Magnehelic < DIFFERENTIAL PRESSURE GAUGE < NEAR Dahej Industrial Area GUJARAT

 

SERIES 2000 MAGNEHELIC® DIFFERENTIAL PRESSURE GAGES Indicate Positive, Negative or Differential, Accurate within 1%

  • No Power Required
  • Low Cost
  • Used in Isolation/ Hospital Environments and Temporary Units (no power required)

Select the Series 2000 Magnehelic® Gage for a versatile low Differential Pressure Gage With a Wide Choice of 81 Models And 27 options to Choose From. Using Dwyer’s Simple,Frictionless Magnehelic® Gage movement, it quickly indicates air or noncorrosive gas pressures–either positive, negative (vacuum) or Differential.The design resists shock,Vibration, over-pressures and is weatherproof to IP67. Select the -HA High Accuracy Magnehelic® Gage option for an accuracy within 1% of full scale, located below in the Product Configurator.Also included with the–HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.

NIST CALIBRATION available in Product Configurator.

Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Please see Series AT-2000 for ATEX approved.

Dwyer Series 1950 Explosion Proof Differential Pressure Switch

  • Set Points from .03 to 20 in w.c., Explosion-Proof And Weatherproof


Series 1950 Explosion-Proof Differential Pressure Switch Combines The Best Features Of The Popular Dwyer® Series 1900 Pressure Switch With an Integral Explosion-Proof And Weatherproof Housing, Making it An Exceptional Value For Either Application. It is CE, UL and CSA listed, FM Approved For use in Class I, Div 1, Groups C and D, Class II Groups E, F, and G and Class III hazardous atmospheres (NEMA 7 & 9), Raintight NEMA 3 (IP54). Weatherproof features include a drain plug and O-ring seal in cover. Electrical connections are easily made by removing front cover. For convenience the set point adjustment screw is located on the outside of the housing. Twelve models offer set points from .03 to 20 in w.c. (0.0075 to 5 kPa) and from .5 to 50 psi (0.035 to 3.5 bar). The unit is very light and compact — about half the weight and bulk of other Explosion-Proof or Weather-Proof Switches with Separate Enclosures.

CAUTION: For Use Only With Air or Compatible Gases. Applications With Hazardous Atmospheres and a single Positive Pressure May Require Special Venting.

SERIES 1950 EXPLOSION-PROOF DIFFERENTIAL PRESSURE
SWITCH

  • Set Points from .03 to 20 in w.c., Explosion-Proof And Weatherproof

Series 1950 Explosion-Proof Differential Pressure Switch Combines The Best Features Of The Popular Dwyer® Series 1900 Pressure Switch With an Integral Explosion-Proof And Weatherproof Housing, Making it An Exceptional Value For Either Application. It is CE, UL and CSA listed, FM Approved For use in Class I, Div 1, Groups C and D, Class II Groups E, F, and G and Class III hazardous atmospheres (NEMA 7 & 9), Raintight NEMA 3 (IP54). Weatherproof features include a drain plug and O-ring seal in cover. Electrical connections are easily made by removing front cover. For convenience the set point adjustment screw is located on the outside of the housing. Twelve models offer set points from .03 to 20 in w.c. (0.0075 to 5 kPa) and from .5 to 50 psi (0.035 to 3.5 bar). The unit is very light and compact — about half the weight and bulk of other Explosion-Proof or Weather-Proof Switches with Separate Enclosures.

CAUTION: For Use Only With Air or Compatible Gases. Applications With Hazardous Atmospheres and a single Positive Pressure May Require Special Venting.
