The DP-702LH differential air pressure sensor board from GrayWolf Sensing Solutions, Shelton, CT, is for use with the company's AdvancedSense and WolfPack air monitoring instruments. The board combines auto-ranging and auto-zeroing technology to provide low-end sensitivity and a broad measurement range. It incorporates both a 250.0 Pa pressure sensor and a 10 kPa pressure sensor and smoothly autoranges from one sensor to the other, depending on the detected pressures. The board autozeroes both sensors every 2 min. to prevent sensor drift. Applications include investigating pollutant pathways, testing filter performance, determining pressure drops, and monitoring/logging positive pressure vs. negative pressure over time for adjacent zones.
