Variety of Thermocouple for different Applications

Thermocouple :

A thermocouple consists of two dissimilar metallic wires joined at one end, known as hot junction. When the hot junction is heated, an emf is produced which corresponds to the temperature difference between the hot junction and free ends known as cold junction. This thermo emf is measured by galvanometric/potentiometer metric/digital instruments, to display temperature.


Thermocouples are used as sensing device for measuring, controlling and recording temperature in range -200°C to 1800°C. Thermocouples are being widely used in various industrial fields such as chemicals, Petro-Chemicals, Fertilizers, Iron & Steel, Non Ferrous metal, Glass, Cement and Refractory factories, Nuclear & Thermal Power Generating plants etc.

Features –

  • Most common, convenient and versatile devices used to measure temperature.
  • Sensing devices for measurement, control and recording of temperature from -200°C to +1800°C.
  • These are available in two basic designs: Straight type & Angle Type.
  • Angle type Thermocouples are used when it is not convenient to use Straight Type Thermocouples or Thermocouple connecting head is desired to be kept away from the place of insertion of Thermocouple so as to avoid attack of harmful fumes and vapors or high temperature.

Resistance Temperature Detector (RTD)
The Principle of temperature measurement using RTD’s is based on the measurement of electrical resistance of a metal wire as it varies with the temperature. Platinum is the most suitable metal for thermometry being mechanically and electrically stable. It can be highly refined and the relationship between the temperature and the resistance is quite linear. Platinum Resistance Thermometers are widely used for temperature measurement at various places including Thermal power plants, Automobiles, Ships, Cooling & Circulating systems, Bearings, Storage Rooms, Furnaces, Ovens and many other applications. RTD
For temperature measurement in the range, -200°C to + 850°C Resistance Temperature Detector (RTD) is preferred to Thermocouple and other sensors because of its higher accuracy, reliability, compact size and faster response. RTDs find use in almost all industries like plastic and rubber processing, food industries, pharmaceuticals, chemical & petrochemical plants, and power plants. It is also used in diesel engines & ships, process control and laboratories for temperature measurement and control.
Features -
  • High accuracy and stability.
  • Wide temperature range; -200°C to +850°C.
  • Fast response & High insulation resistance.
  • Needs only copper cables for long runs.
