<p>The invention relates to a thermocouple integrity measuring arrangement comprising a thermocouple (22), a controller/processor (12), a multiplexer/digitiser (11) and a test circuit (23), the controller/processor is arranged to receive a temperature reading from the thermocouple and to switch the multiplexer/digitiser to the test circuit (23), the test circuit being capable of inputting a test signal to the thermocouple for the controller/processor to receive the test reading whereby the controller/processor is capable of determining whether the test reading is indicative of a closed or open circuit and accepting or rejecting respectively the temperature reading.
The invention also relates to a method of determining the integrity of a thermocouple.</p> |
