TEMPERATURE ELEMENTS Thermocouples / RTD Assemblies.

     Thermocouple (T / C)

     Resistance Temperature Detector (RTD)

  • It employes two dissimilar metals

  • When two such dissimilar metals welded together at one end and subjected to heat, it develops a small DC voltage (EMF), corresponding to temperature difference between hot junction (measuring junction) and cold junction (reference junction).

  • The temperature - EMF characteristics have an established pattern for different type of hermocouple elements like,
    T, J, K, N, E, R, S, etc.

  • Temperature - EMF characteristics conform to
    ANSI MC 96.1 / IEC 584 / DIN 43710 standards.
  • It employs high purity electrical resistance wire, non inductively wound on ceramic or glass base.
  • When RTD element is subjected to heat, it changes its electrical resistance value, corresponding to variation in temperature and its thermal coefficient (œ) (Alpha).

  • The temperature resistance characteristics have an established pattern for different resistance elements, like Copper, Nickel, Platinum etc.

  • Most commonly used resistance element is Platinum known as Pt 100 (100 ohms at 0°C).
  • Temperature resistance characteristics conform to DIN 43760 / IEC 751 / BSS 1904 / JIS C1604 standards.
  • Conventional thermocouple or RTD elements pass through multi bore insulators, encased in outer protection sheath and connected to temperature measuring instrument.

  • Mineral insulated (MI) sensors are insulated with tightly compacted high purity magnesium oxide powder, simplex or duplex, enclosed in various metal sheaths and connected to temperature measuring intrument.


  • Staninless Steel, Die Cast Aluminium with cable entry.
  • Protection : IP, Flame Proof Gr IIA, IIB or IIC, Increased Safety.
  • Termination : Brass/SS connectors with markings for polarity, colour codes and type of Thermocouples.
    Spring Loaded Terminal Block - if required.
