605-50 is a series 605 Magnehelic® differential pressure 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 gauge is complimented by the 2-wire, 4-20mA control signal utilizing the time-proven Dwyer® Magnehelic® gauge mechanical design and series 600 transmitter technology. The 2-wire design with terminal strip on the rear simplifies connection in any 4-20 mA control loop powered by a 10-35VDC supply.
