• Proving flow through a pump
Series 1831,Dwyer, DPDT Low Differential Pressure Switches
Manual Reset, No Power Required
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 APPLICATIONS
• High duct static cutout applications • HVAC
Series 1900 COMPACT LOW DIFFERENTIAL PRESSURE SWITCHES
Set Points from 0.07 in to 20 in w.c. Repetitive Accuracy within 3%
FEATURES/BENEFITS

The Series BYDS Bypass Damper Switch is designed to control motorized
bypass dampers. As individual zone dampers open and close, the system static
pressure will rise and fall. In order to maintain proper airflow and static pressure
through the HVAC system
The SERIES DH3 Digihelic® Differential Pressure Controller is a 3-in-1 instrument possessing a digital display gage FEATURES/BENEFITS • 3-in-1 instrument allows the reduction of several instruments with one product, saving inventory, installation time and money • Full scale accuracy of 1% even on extremely low ranges, and 0.5% for ranges above 5 in w.c. provide for greater measurement precision • Secure menu program provides access to device operation only for the right skill level • Optional stainless steel bezel is the same installation diameter as Magnehelic® gage and simplifies field upgrade to DH3 pressure controller APPLICATIONS • SCFM duct flow • Filter status • Duct or building static pressure • Damper and fan control
