Thermocouples are temperature sensors made up of two dissimilar metals which are joined at one end forming a hot junction and the open wire end acting as the cold junction, the hot junction is in contact with the process. When the measuring point i.e. hot junction gets heated there is an EMF produced at the cold junction, which is produced due to difference in electron density of the two dissimilar metals and temperature difference between cold end and hot end.

We at Tempsens offer various models of standard thermal sensors, including all types of accessories all of which meet the most diverse technical requirements. We offer thermocouples that are highly resistant to vibrations, corrosion etc.

Thermocouple elements are made from metals that have material specific electro negativities in order to achieve the highest possible thermoelectric voltages. Thermocouples are available in both class 1 and class 2 as per IEC 60584 and some standard and special classes in accordance with ASTME230.
