GrayWolf Sensing Solutions: Differential Air Pressure Sensor Board
April 23, 2012
By combining auto-ranging and auto-zeroing technology, the DP-702LH differential air pressure (∆P) sensor board offers low-end sensitivity and a broad measurement range. The unit incorporates a 250-Pa (1 inch H2O) range sensor and a 10-kPa (40 inches H2O) sensor on the same board and then smoothly auto-ranges from one sensor to the other, dependent on the detected pressures. The board auto-zeroes both sensors every 2 minutes. The ∆P sensor configuration is now available for use with the AdvancedSense™ and WolfPack™ instruments, which not only display and data log readings, but also provide powerful annotation capabilities. Notes are easily attached to data files on-site for efficient, reliable documentation. The user can add text notes via the virtual keyboard and can attach extensive audio notes with the built-in voice recorder. Photos and videos can be attached to data files with an optional camera or borescope. Reports are generated from information in the field. WolfSense PC software (supplied as standard) enables simple download, analysis, and report creation. Optional “Advanced Report Generator” software automates the entire reporting process.
