Bestech Australia presents a new data acquisition system from Validyne ideal for vehicle HVAC low pressure, vent and duct air pressure measurements.
Validyne’s new VPAS (Vehicle Pressure Acquisition System) offers up to eight low pressure channels (measurement points) with continuous pressure reading recording and a USB interface to display data in real time graphically on a laptop or PC. The readings can be saved in .csv format for further analysis in MS Excel.
The VPAS is designed to be placed on the rear seat of a vehicle with plastic hoses running from the differential pressure sensors (DP103). DP103 sensors have a full range from 0.1in H2O up to 55in H2O, and are referenced to ambient cabin pressure when negative ports are left open, while sensing differential pressure when the tubes are connected to both positive and negative ports.
