Ms Mi Thermocouple or Resistance Thermometer sensor fitted into a terminal head, and provided with head extension and solid sintered Tungsten carbide thermowell would form typically, a complete assembly for use in Power Plants for highly abrasive services such as mill classifier outlet for temperature measurement of Coal + Air Mixture.
For use at relatively high temperatures we recommend re-crystallized Silicon carbide, which also has a very high abrasion resistance characteristics. These are recommended for use in Flue gas application in power plants or for use on incinerators employed in mordern day waste management systems of process plants. Standard well is available in diameter of 20mm; and is cemented into stainless steel bushing.
The standard execution as shown in this leaflet is with plated CS extension and Aluminum head with conduit entry of 1/2" NPT(M) and well entry of M20x1.5, and an ungrounded Thermocouple. |

Thermocouples or Resistance Thermometers are often required with Thermowells which can withstand corossion caused by the process medium. It is expensive to manufacture bar stock Thermowells in materials which can withstand the corrosion. An effective and less expensive alternative is to manufacture the thermowells from 300 Series barstocks and provide a sleeve or lose lining over the entire wetted portion of the well including the raised face of the flange, which can withstand the corrosive attack from process medium.
Thermowells can be provided with lining in various materials such as Tantalum(Ta), Titanium(Ti), Nickel(Ni), Hastelloy 'C', Hastelloy 'B', Silver(Ag) and Platinum-Rhodium alloy (PtRh).
The standard execution as shown in this leaflet is with plated CS extension and Aluminum head with conduit entry of 1/2" NPT and ungrounded junction for unless specified otherwise. |
