Thus the platinum: 10 per cent rhodium-platinum thermocouple is designated “Type S” and the platinum: 13 per cent rhodium-platinum thermocouple is referred to as “Type R”. The differences between the new reference table incorporated in BS and the former standards NBS Circular and BS (adjusted to IPTS–68) for the Pt: 13%.
Type R Thermocouple (Platinum Rhodium % / Platinum): The Type R is used in very high temperature applications. It has a higher percentage of Rhodium than the Type S, which makes it more expensive.
The Type R is very similar to the Type S in terms of performance. At Nordic Sensors Industrial Inc, we manufacture platinum thermocouples according to your needs.
Feel free to use our configuration tools to build your type S, type B or type R thermocouple. You may also let our engineering department custom-design and build your platinum thermocouples the way you require. A new type of platinum:platinum-rhodium thermocouple wire which incorporates traces of yttrium in the platinum limb has been developed and tested in some typical working environments.
This thermocouple possesses good thermal stability and mechanical strength at high temperatures, and a long service life, compared with conventional platinum:platinum-rhodium thermocouples.

From Abstract: "Revised reference data for thermocouples have been generated in a cooperative program between groups of the National Bureau of Standards in Boulder and Monograph contains tables, analytic expressions, various approximations, and explanatory by: A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction.A thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure couples are a widely used type of temperature sensor.
Commercial thermocouples are inexpensive. Platinum Thermocouples 9. 1 General Remarks Thermocouples employing platinum in combination with platinum-rhodium alloys, gold, or palladium have been found to be the most reproducible of all the various types. They are resistant to oxidation in air and, because of their high melting points, can be used up to very high temperatures.
Scope. This specification covers non-insulated platinum-rhodium alloys (weight percent composition), and platinum thermoelements that meet the requirement of Specification E and NIST Monograph This specification does not cover platinum and platinum-rhodium materials, that require a higher purity than specified insuch as used for temperature coefficient of resistance.

Roeser and H. Wensel, BS J. Resea () RP The tables for platinum versus platinumpercent. In thermocouples, platinum is often combined in an alloy with rhodium, a chemically inert transition metal which is also part of the platinum group.
Types of platinum thermocouple. The ratio of platinum to rhodium depends on the type of thermocouple. Type B Thermocouple Wire. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Description. OMEGA™ Exotic Thermocouple Probes are designed for use in extreme temperatures, up to °C (°F). These probes utilize either Platinum/Rhodium (types R, S, or B) or Tungsten/Rhenium (types G, C, or D) elements, with a variety of insulations and sheath materials.
Surepure Chemetals sells platinum-rhodium wire and pure platinum wire for use in thermocouples. Whereas platinum has a Young's modulus of GPa, the Young's modulus of rhodium is GPa. As would be expected, platinum-rhodium alloys have substantially higher mechanical strength at all temperatures than chemically pure platinum.
Standard tables giving the e.m.f.s at different temperatures are available for the metals usually used for thermocouples. Commonly used thermocouples are listed in Tablewith the temperature ranges over which they are generally used and typical sensitivities. These commonly used thermocouples are given reference letters.

A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is.AnHui TianKang (Group)Shares Co.,Ltd.
