One of our most famous differential tension switches is presently accessible with a DPDT switch and manual reset. The Series 1831 joins little size with 4% set point repeatability. Positively no power is expected to work the DPDT switch. Set point change on the switch is effectively available for adjusting the set point.

Series 1831 DPDT Low Differential Pressure Switches
Manual Reset, No Power Required

The Series 1831 DPDT Low Differential Pressure Switches with Manual Reset dispose of normal issues related with average high pipe static pattern establishments. Since the 1831 requires definitely no ability to drive its results, a different power circle and its related extra wiring and conductor is lightened, lessening material and work establishment costs. Both control contacts of the Series 1831 initiate simultaneously. The capability of the lead switch closing down the fan forestalling the slack change from conveying a disturbing message to the DDC is presently not a plausible framework risk. Potential exorbitant support calls are lessened. Not at all like normal switches that groups just a solitary conductor section for both control circles, the Series 1831 gives two course associations improving on wiring while at the same time wiping out extra channel tees. The Series 1831’s determinations and highlights go with it the prevalent decision for high channel static pattern applications.

Product Applications :
* High duct static cutout applications
* HVAC

Features :
* 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
