Abstract:

The construction and use of a programmable, fully automatic data acquisition and control system MIDAS 4 is reported with application to probe surveys in a turbomachine. The MIDAS 4 system was designed to record up to 48 channels of analog data, position and align a pneumatic probe in the direction of flow in surveys across a flow passage, and control the operation of up to four Scanivalve pneumatic switches. The MIDAS 4 input and output is presently via a teletypewriter keyboard and paper-tape punch. A direct interface with the Hewlett-Packard HP 9830A calculator is a logical modification of the system.
