ABSTRACT:
A self-contained and internally powered shock, temperature and relative humidity acquisition and recording device particularly adapted for the rapid, accurate and automatic analysis of material handling and transportation facilities and procedures. The apparatus includes transducers which are used to sense shock, temperature and humidity in analog form. The analog signals generated by the transducers are converted to digital signals, i.e., binary multi-bit words which by means of digital logic and solid state memory devices, statistical and time dependent information are stored for an operating interval as long as two weeks. Thereafter the device is coupled to an interrogation system which generates output records from the collected data in operator selected density profiles or time histories.
