Česky (CZK)Magnehelic® Transmitter for Low DP Monitoring in HVAC
Easy to read gage permits viewing from far away. Patented design provides quick response to pressure changes means no delay in signaling and alerting to critical situations. Durable and rugged housing and high-quality components combined provides long-service life and minimized down-time. Optional stainless steel bezel is the same installation diameter as Magnehelic® gage and simplifies field. More
The Series 605 Magnehelic® Indicating Transmitter provides for both visual monitoring and electronic control of very low differential pressure. The Series 605 is ideal for control applications in building HVAC systems where local indication is desired during routine maintenance checks or necessary when trouble shooting the system.
The easily read dial gage is complimented by the two-wire, 4 to 20 mA control signal utilizing the time-proven Dwyer® Magnehelic® gage mechanical design and Series 600 transmitter technology. The two-wire design with terminal strip on the rear simplifies connection in any 4 to 20 mA control loop powered by a 10 to 35 VDC supply.

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...
