General
The Banner Engineering QM42-DPS20-2Q is an industrial differential pressure sensor designed to measure pressure differences in gaseous applications. With a measurement range of ±20 inches of water column (in. W.C.), it is suitable for monitoring air pressure differences in HVAC systems, air handling equipment, filtration systems and industrial process applications.

The sensor features an RS-485 Modbus communication interface, enabling pressure measurement data to be integrated with PLCs, controllers and industrial monitoring systems. Operating on a 10–30 V DC supply, it includes a 2.09 m (6.9 ft) 5-pin M12 pigtail quick-disconnect cable and an IP67-rated enclosure for industrial installations.
