Series 1831 DPDT Low Differential Pressure Switches
One of our most popular differential pressure switches is now available with a
DPDT switch and manual reset. The Series 1831 DPDT Low Differential Pressure
Switches combine small size with 4% set point repeatability. Absolutely no power
is required to operate the DPDT switch. Set point adjustment on the switch is easily
accessible for modifying the set point.
The Series 1831 DPDT Low Differential Pressure Switches with Manual Reset eliminate
common problems associated with typical high duct static cutout installations. Since
the 1831 requires absolutely no power to drive its outputs, a separate power loop
and its associated additional wiring and conduit is alleviated, reducing material and
labor installation costs. Both control contacts of the Series 1831 activate at the same
time. The potential of the lead switch shutting down the fan preventing the lag switch
from sending an alarming signal to the DDC is no longer a probable system liability.
Potential costly maintenance calls are diminished. Unlike typical switches that possess
only a single conduit entry for both control loops, the Series 1831 provides two conduit
connections simplifying wiring while eliminating additional conduit tees.
