MAGNEHELIC® DIFFERENTIAL PRESSURE INDICATING TRANSMITTERSame Size as Standard Magnehelic® Differential Pressure GageDWYER INSTRUMENTS, INC. | dwyer-inst.com66The 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 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 10-35 VDC supply.FEATURES/BENEFITS• 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 upgrade to 605 indicating transmitterAPPLICATIONS• Monitor pressures in ducts, rooms, or total building pressures• Filter monitoring • Local indication of clean room pressures with process signal sent to control room23/32[18.26]1[25.40]30°1-1/8[28.58](3) #6-32 x 3/16 [4.76]DP HOLES EQUALLY SPACEDON A Ø4-1/8 [104.78] B.C.FOR PANEL MOUNTING11/16[17.46]1/8 FEMALE NPTLOW PRESSURE CONNECTION1/2 [12.70]1-3/4[44.45]1/8 FEMALENPT HIGHPRESSURECONNECTION2-1/16[52.39]2[50.80]1-1/4[31.75]2-1/2[63.50]3/16[4.76]5/8 [15.88] PANEL MAXØ5[127.00]Ø4-47/64[ 120.25](4) 6-32 HOLESEQUALLY SPACED ON A 5-1/8 [130.18] B.C.FOR FLUSH MOUNTINGØ4 [101.60] FACE5-1/2 [139.70]O.D.
