【 摘 要 】

This report documents the flight qualification testing of the Dallas/Maxim iButton temperature logger, model DS1922L, for internal mounting to the W80 Air Launched Cruise Missile (ALCM). A single thermal test was performed utilizing a Thermotron Model S-1.2V, S/N 20330-S, Environmental Chamber, an Agilent 34970A Data Acquisition/Switch unit, S/N MY44002670, with a Agilent 34901A 20 channel multiplexer, S/N MY41038424, and a single J type thermocouple. Start, stop, chamber temperature and temperature profile control of the Themotron was accomplished using a custom LabView VI. Additional chamber thermal data from the Agilent unit, for comparison with the Thermtron thermocouple, was captured using Agilent BenchLink software. The thermal test was performed in Building 131, Room 2273, at Lawrence Livermore National Laboratory, Livermore, California. One hundred twenty eight (128) DS1922L temperature loggers were setup and tested simultaneously.
