T type thermocouple Manufacturer in Ahmedabad

A typical form of temperature sensor in many commercial and industrial applications is the T type thermocouple. It is made up of a junction formed by the joining of two separate metal wires at one end. Copper (positive leg) and constantan (negative leg) are the most often utilized metals.

A temperature difference produces a voltage that is proportionate to the difference in temperature between the junction, or the point where the two metals converge, and the other ends of the wires, which are attached to a measurement device. We refer to this idea as the Seebeck effect.

Particularly in low-temperature applications, T type thermocouples are renowned for their precision and dependability (usually up to roughly 350°C or 660°F). They are commonly employed in fields where accurate temperature monitoring is essential, such as scientific research, HVAC systems, and food processing. A T type thermocouple may be used in a range of procedures and conditions since its output generally falls between -200°C and +350°C (-328°F and +662°F).

The three main components of a T type thermocouple are:

  1. Positive leg (T+) : Typically made of copper, it is one of the two dissimilar metal wires that form the thermocouple junction.
  2. Negative leg (T-) : Usually made of constantan, it is the other dissimilar metal wire that, together with the positive leg, forms the thermocouple junction.
  3. Insulation : This surrounds the two legs to electrically isolate them from each other and from the environment. The insulation material can vary but is designed to withstand the temperature range the thermocouple is intended to measure.
