What Is a Thermocouple Probe?
A thermocouple probe is a sensor widely used in various fields, including medical and industrial settings, for temperature measurement.
Its operation is based on the Seebeck effect, which is fundamental to the thermocouple‘s temperature measurement principle.
The Seebeck effect occurs when dissimilar metals are connected in a loop circuit; a temperature difference applied at each junction generates a potential difference. This potential difference, which depends on the types of metals used and the temperature difference, allows for the calculation of the measured temperature at the desired measurement location by correlating it with the generated potential difference.
When selecting a thermocouple probe, it is crucial to choose the appropriate type based on specified standards, as the measurable temperature range and accuracy vary with the thermocouple type.
