1831 DPDT Low Differential Switch
Dwyer, 1831-2-RA-S, Series 1831 DPDT Low Differential Pressure Switches, 7.5-23' w.c.Manual Reset, No Power RequiredOne of our most popular differential pressure switches is now available with a DPDT switch and manual reset. The 1831 combines 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 posses only a single conduit entry for both control loops, the Series 1831 provides two conduit connections simplifying wiring while eliminating additional conduit tees. The Series 1831's specifications and features make it the superior choice for high duct static cutout applications.FeaturesBoth contacts activate and reset at the same timeNo power required to operateDual conduit openings for each control loopIncluded bracket for mounting quickly.
