FOOD PROBE THERMOCOUPLE

There are many types of probes used in restaurant equipment for the measurement of temperature, humidity, liquid level, ice level, product or ingredient levels and other critical operating limits and control points (HACCP). A probe is a small device, especially an electrode, used for measuring, testing, or sensing and obtaining information. Probes are commonly thin and oblong, and may be flexible. They provide data output to other components to control operation of the equipment. 

A thermocouple is a transducer consisting of two different metals welded together at each end; a voltage is produced that is proportional to the difference in temperature between the two junctions (one of which is normally held at a known temperature).  Commercial thermocouples are inexpensive, interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self powered and require no external form of excitation.
