Series 605 Magnehelic
®
Differential Pressure Indicating Transmitter
Specications - Installation and Operating Instructions
Bulletin E-68
The Series 605 Magnehelic
®
Differential Pressure 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 in 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.
