| The Dwyer 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 to 20 mA signal for ranges
from 0 to 1 to 0 to 10" 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 pressure
gauge. However, the Series 605 models add electrical conditioning and
amplification of a resistance change produced by a silicon strain gauge
which is cemented to the range spring. This resistance change is the
result of the slight flexing which results from spring deflection as
pressure is applied to the diaphragm which is directly linked to the
spring. Refer to bulletin E-50 for additional information on the design,
operation and construction of the Magnehelic® indicating
transmitter.
