The 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 gage is complimented by the 2-wire, 4-20 mA
control signal utilizing the time-proven Dwyer
and Series 600 transmitter technology. The 2-wire design with terminal strip on the rear
simplies connection in any 4-20 mA control loop powered by a 10-35 VDC supply.
BENEFITS/FEATURES
• 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 simplies eld upgrade to 605 indicating transmitter
APPLICATIONS
• Monitor pressures in ducts, rooms, or total building pressures
• Filter monitoring
• Local indication of clean room pressures with process signal sent to control room
