Platinum Nobel Metal Thermocouple Assembly With Ceramic Protection Tube
Product Description:
Platinum Nobel Metal thermocouple temperature sensors, most commonly ANSI types R, S, and B, are precious metal sensor elements (noble metals) that are used primarily in high temperature sensing applications. The platinum thermocouple sensors provide long, stable service where standard base metal thermocouple calibrations are inadequate. Platinum thermocouple sensor elements can be supplied in a variety of protective assembly designs. These include ceramic protection tubes with secondary insulators, silicon carbide protection tubes, or compacted mineral insulated (MgO) cable designs. Custom designed platinum thermocouple temperature sensors or standard designs are available.

Feature:
Type R thermocouple
This thermocouple is made from Platinum which is the negative leg and much softer and Platinum 13% Rhodium which is the stiffer positive leg. It is suitable for use in oxidising or inert atmospheres and may be used under reducing conditions or in a vacuum provided care is taken to ensure the refractory materials are free from siliceous materials. Pure recrystallised alumina is recommended. This thermocouple is suitable for continuous use up to 1400 C and for intermittent use up to 1650 C.
Type S thermocouple
This thermocouple defines the international practical temperature scale between Antimony point (630.73 C ) and the gold point (1064.43 C). This thermocouple is made from Platinum which is the negative leg and much softer and Platinum 10% Rhodium which is the stiffer positive leg, and has the same operating requirements as type R. Again This thermocouple is suitable for continuous use up to 1400 C and for intermittent use up to 1650 C.
Type B thermocouple
This combination platinum thermocouple is made from Platinum-30% Rhodium and Platinum -6% Rhodium. When they are compared to pure platinum thermocouples they suffer less from the effects of 'Rhodium migration' and may be used at somewhat higher temperatures, continuous operating 1500 C and up to 1800 C intermittently.
Mullite Protection Tubes
1. Maximum temperature range 2800°F.
2. Impervious to gasses at high temperature.
3. Good shock and chemical resistance.
Alumina Protection Tubes
1. Maximum temperature range 3200°F.
2. Fair shock resistance, preheating recommended.
3. Resists chemicals, will not contaminate platinum.
Application:
The Noble metal thermocouples (also called rare metal thermocouples) are used for measurement of higher temperatures.
1. Glass Industry
2. Semi-conductor Industry
3. Type S thermocouples are regularly used in the electric arc furnace process to accurately measure the steel's temperature before tapping. The cooling curve of a small steel sample can be analyzed and used to estimate the carbon content of molten steel.
