The Series 605 Magnehelic® Indicating Transmitter simultaneously provides local indication on a large, easily read analog scale while also converting that pressure into a standard two-wire, 4-20 mA signal for ranges from 0-0.5 to 0-50˝ w.c. Positive, negative or differential air and compatible gas pressure can be measured with accuracies as low as ±.5% of full scale. The basic mechanical components of the Series 605 Magnehelic® indicating transmitter are similar to those used in the popular, time-proven Magnehelic® differential pressure gage.

INSTALLATION

1.LOCATION: Select a location where the temperature of the unit will be between 20°F and 120°F. Distance from the receiver is limited only by total loop resistance. See “Electrical Connections”. The tubing feeding pressure to the instrument can be run practically any length required but long lengths will increase response time slightly. Avoid surfaces with excessive vibration.

2.POSITION: All standard models are calibrated with the diaphragm vertical and should be used in that position for maximum accuracy. If your application requires mounting in other than a vertical position, be sure to specify this when ordering.

3.PRESSURE CONNECTIONS: For convenience, two sets of 1/8˝ female NPT ports are available. Plug the unused set with pipe plugs provided. Attach tubing from positive pressure source to port marked “HI” or from negative (Vacuum) source to port marked “LOW”. In either case, opposite port must be vented to atmosphere. In dusty environments, we recommend use of an A-331 Filter Vent Plug to keep interior of instrument clean. For differential pressures the higher source is connected to the “HI” port and lower to the ”LOW” port.

4.MOUNTING: The Series 605 Transmitter may be either panel mounted or surface mounted.

SNAP RING GROOVE

PNEUMATIC PRESSURE TAPS

4-3/4 DIA. HOLE

A.PANEL MOUNTING: Cut a 4-3/4˝ or 120mm dia. hole in panel and insert the complete unit from the front. Slip on the mounting ring and install the split snap ring in the groove on the bezel. Seat the mounting ring against the snap ring and thread the four screws through the tapped holes. Tighten screws against rear of panel.

B. SURFACE MOUNTING: Drill (3) 3/16˝ dia. holes for mounting screws and cut (1) 7/8˝ x 1-1/8˝ hole for access to terminal strip as shown in hole location drawing. Insert screws from rear of panel and thread into tapped holes on back of transmitter case. If rear pressure connections are to be used, make 1/2˝ dia. holes located as shown in hole location drawing in left column.

5.ZEROING: Once gage/transmitter is mounted in its final position, check to be sure pointer aligns with zero on scale, when no pressure is applied and both low and high pressure ports are vented to atmosphere. To adjust, turn small slotted screw at center-bottom of gage face. Do not move the larger black knobs labeled SPAN and ZERO. These are for use only if a calibration check shows the 4-20 mA output signal to need adjustment. See page 3 under heading OUTPUT RANGING.
