ABSTRACT:
An adapter to permit a temperature measuring instrument ordinarily used with a thermistor temperature sensor to be used with a temperature probe of the thermocouple type. The adapter has an output for connection to the temperature measuring instrument and has circuitry for processing the signal from the thermocouple probe to produce at the adapter output a resistance which a thermistor sensor would generate at the same temperature. A temperature measuring instrument for efficient use of an electrical source has circuitry for processing a temperature related signal according to a sequence of operations to provide an electrical variable having a value which is a function of the temperature being measured. The sequence commences with connection of the electrical source to the processing circuitry. At the completion of the sequence a signal indicative of completion is produced. In responsive to the completion signal the electrical source is disconnected from the processing circuitry. The electrical source is reconnected to the processing circuitry a predetermined time after the disconnection.
