Tube Skin Thermocouples

Tube Skin Thermocouples manufactured by us are reliable for measurement and control of tube sur face temperature in fire heaters. Accurate temperature measurement is impor tant for prolonging heater tube life, for ensuring safe and efficient operation. We have been supplying tube skin thermocouple assemblies in quantities to majority of the projects in India as well as expor ting to various countries. The basic thermocouple is normally of 12.7 mm OD with relatively higher sheath wall thickness, mineral insulated (compacted MgO) and in variety of sheath materials such as SS310, SS446, Inconel 600, Incoloy 800 etc. The Junction is generally grounded. However ungrounded junction also is offered, as customer requires. Mineral Insulated (MI) thermocouple is manufactured by Cold drawing and annealing (heat treatment) process in controlled atmosphere. The heat treatment (which is 0 controlled within +- 2 C) is carried out in hydrogen atmosphere to avoid sur face defects & par tial oxidation of conductor.
