Multiple pressure data acquisition has typically consisted of hundreds of pipes connected via a test-bed interface to mechanical multiplexers and/or to groups of electronically scanned sensors. This paper describes a new method of high speed digital pressure scanning with intelligent pressure modules and its consequent impact on turbine testing methods and working practices. Also discussed is the remote calibration of modules and the concept of pre-rig or build shop connecting pressure tappings direct to the test measuring equipment, thus reducing commissioning, calibration and down time on the test-bed.
