Abstract
The temperature function integrator disclosed senses the temperature of a temperature sensitive food and provides as an output a measure of the food deterioration. A temperature transducer produces an electrical signal which is modified according to a transfer function simulating the temperature -- rate of deterioration relation for the food by either analogue or digital means. The modified signal determines the pulse rate or the number of pulses generated at a sample time by a pulse generator, and these pulses are counted by a digital counter which performs an integrating function. A number of counters can be used to give deterioration for a number of selected temperature ranges. An integral or remote read-out decodes the counter. Rate of deterioration and absolute deterioration information may be telemetered to a remote receiver and read-out.
