Dwyer Instruments 605 - User Manual

The Dwyer
Series 605 Magnehelic
®
Indicating Transmitter simulta-
neously provides local indication on a large, easily read ana-
log 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 an accuracy of ±2% 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 pres-
sure gage. However, the Series 605 models add electrical
conditioning and amplification of a resistance change pro-
duced by a silicon strain gage which is cemented to the
range spring. This resistance change is the result of the
slight flexing which results from spring deflection as pres-
sure is applied to the diaphragm which is directly linked to
the spring.
