Česky (CZK)Magnehelic® Differential Pressure Transmitter
No Power Required. Easy to read gage through undistorted plastic face. Patented design provides quick response to pressure changes. Durable and rugged housing and high-quality components for long service life. Bezel provides flange for flush mounting in panel. More
Select the Magnehelic® 2000 Series 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.
Product applications:
Filter Monitoring, Air Velocity with Dwyer Pitot Tube, Blower Vacuum Monitoring, Fan Pressure Indication, Duct, Room or Building Pressures, Clean Room Positive Pressure Indication.
Used in Isolation/ Hospital Environments and Temporary Units (no power required)
Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Pressure Transducers and Transmitters
A pressure transducer, often called a pressure transmitter, is a sensor that converts pressure into an analog electrical signal. Although there are various types of transducers, one of the most common is the strain-gage wheatstone bridge pressure transducer.
The conversion of pressure into an electrical signal is achieved by the physical deformation of strain gages which are bonded into the diaphragm of the pressure transducer and wired into a wheatstone bridge configuration. Pressure applied to the transducer produces a deflection of the diaphragm which introduces strain to the gages. The strain will produce an electrical resistance change proportional to the pressure...
