The
Dwyer 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 complemented by the two-wire,
4-20 mA control signal utilizing the time-proven Dwyer Magnehelic®
gage mechanical design and Series 600 strain-gage transmitter technology.
The two-wire design with terminal strip on the rear simplifies connection
in any 4-20 mA control loop powered by a 12.3-35 VDC supply.
