Series 605 Magnehelic® Differential Pressure Indicating Transmitter
Specifications - Installation and Operating Instructions
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 pop-
ular, 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.

4-3/4 DIA. HOLE
A. PANEL MOUNTING: Cut a 4-3/4˝ or 120 mm 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
7
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.
