Trisonic Wind Tunnel
Pressure Measurements
- absolute pressure transducers with capacities from 4.14 bar to 13.8 bar and ±0.05% accuracy
- differential pressure transducer with a capacity of ±1.03 bar and ±0.05% accuracy
- absolute pressure transducers with capacities from 0.69 to 6.9 bar and 0.25% accuracy ;
- differential pressure transducers with capacities from 0.34 bar to 13.8 bar and 0.25% accuracy
Pressure distributions are determined using classical scanivalves and/or an electronic scanning device type ZOC 23B/32Px with 32 transducers of ±50 psid capacity from Scanivalve Corporation.
Unsteady pressures are recorded using the miniature Kulite XCS-152-0.7 bar differential pressure transducers.
Transducers calibration is normally done by a secondary standard Texas Instruments 156 and periodically by a primary pressure standard
