The object in the image is a thermocouple.
A thermocouple is a temperature sensor that measures temperature by converting thermal energy into electrical energy. It consists of two dissimilar electrical conductors forming electrical junctions at differing temperatures. The key components observed in the image are:
Coiled Cable:
This indicates the length of the thermocouple wire, often protected by an outer sheath.
Metal Tip:
This is the sensing junction, typically enclosed in a protective metal sheath (like stainless steel) to withstand various environments and provide a faster response time.
Connectors:
The red and blue spade connectors at the end are used to connect the thermocouple to a measuring device, such as a temperature controller, data logger, or multimeter.
