•FOUNDARIES STANDARD ELEMENT WIRE DIAMETER
•IRON & STEEL 3.2mm. 2.5mm and 1.6mm for type Jand K
thermocouples and 0.45mm, 0.4mm and
•REFRACTORY FACTORIES
0.33mm for type Rand type S thermocouples.
•FERTILIZERS
PROTECTING SHEATH
•PETRO CHEMICALS Thermocouple element is protected by
metallic or non-metallic protective sheath,
proper selection of outer sheath depends on
field conditions at site such as Continuous
Temperature, Mechanical Injury, Chemical
Attack etc. Our standard diameter of metallic
sheaths are approximately 22mm OD and wall
thickness 2mm, the non-metallic protection
tubes in 1.5mm and 24mm outer diameter.

Thermotech thermocouples cover a wide range of temperature measurement in a

number of solids, liquids and gases in a variety of applications in the industries like
Cement, Glass, Ceramic, Heat Treatment, Iron & Steel, Power Station etc. Over the
normal range from – 200 C to +1800 C. The thermocouple essentially, consists of a
thermo-element, a protective sheath, connecting head and adjustable flange or some
other mounting arrangement.
