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., The Series 1831 provides two conduit connections simplifying wiring while eliminating additional conduit tees Features & Benefits:

No power to operate DPDT switch means no additional wiring or conduit reduces material and Installation labor costs

Easy access for modifying set point simplifies adjustment

Both control contacts activate at the same time eliminating system issues where lead switch activities prevent the lagging switch from sending a signal

High duct static cutout applications

HVAC

Dual conduit openings for each control loop

Included bracket for mounting quickly
