SELF-CONTAINED MICROCIRCUITRY PROBE ACQUIRES AND RECORDS FOOD-PROCESS TEMPERATURE DATA.
Author(s) : CROSS W. R., LESLEY D. R.
Type of article: Article
Summary
TWO MICROPROCESSOR BASED TIME-TEMPERATURE INTEGRATORS WERE EVALUATED AND COMPARED WITH CONVENTIONAL THERMOCOUPLE TECHNIQUES NORMALLY USED IN RETORTS IN THE HEAT PROCESSING INDUSTRY. THE INDICATORS HAD RANGES OF 233 TO 353 K (-40 TO 80 DEG C) AND 283 TO 423 K (10 TO 150 DEG C), WERE CAPABLE OF OPERATING IN TEMPERATURES OF 423 K, AND WERE FULLY SUBMERSIBLE. STORAGE IS EQUIVALENT TO 1,000 TEMPERATURE READINGS AND THE UNIT IS POWERED BY LITHIUM BATTERIES. ACCURACY IS MAINTAINED BY EXHAUSTIVE COMPUTER CONTROLLED TESTS BEFORE THE BATTERY IS ADDED. A SPECIAL CONSOLE HAS BEEN DEVISED FOR DATA RETRIEVAL. COMPARISONS WITH THERMOCOUPLES DURING A RETORT PROCESS SHOWED GOOD AGREEMENT IE WITHIN 1% AT 373 K (100 DEG C) AND SOMEWHAT BETTER AT 333 K (60 DEG C). G.R.S.
