Development of a 100 Channel Multiplexer for Acquiring Model Data from the Rent Facility

Abstract

A need for multiplexing thermocouple signals was recognized in 1972 by the RENT Facility Managers. Initial funding was provided for in FY 73. The problem was assigned to AFFDL/FXN, Electronics Group. Mr. Bieber, Technical Manager of the Electronics Group, assumed the role of Principal Investigator. He began a study to incorporate this multiplexer in the overall separation of instrumentation for the RENT operations and the HTL operation. This study revealed the long term need for twenty channels for each of the RENT's five model positions. Further, it was found that each channel must service any type of electrical signal normally found in wind tunnel model instrumentation. The responsible managers met, studied, and decided upon a multiplexing system concept which would be in harmony with the longer range instrumentation separation problem. This report expands upon the conversion of this concept into operational hardware.
