The Dwyer AT2605 indicating pressure transmitter essentially combines an analog pressure gauge and a pressure transmitter in a flameproof ATEX approved enclosure. This unique, dual design allow 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 Dwyer AT2605 series is available in ranges up to 50 inH2O or 1.5 kPa. The instrument has a mechanical accuracy of up to ±2% of FS while the transmitter is accurate to ±0.5% of FS. The easily read 4-inch dial gauge is complimented by the two-wire, 4-20 mA control signal utilizing the time-proven Dwyer Magnehelic® gauge mechanical design and Series 600 transmitter technology. The two-wire design with terminal strip on the rear simplifies connection in any 4-20 mA control loop powered by a 10-35 VDC supply.
