Antioxidant Tungsten Rhenium Thermocouples

Technical description:
Temperature measurement is the eyes of the industrial production and scientific research. However, this high temperature measurement, particularly  the automatic control  of high temperature, still is the  expensive platinum-rhodium thermocouple .Conventional tungsten rhenium thermocouple is capable of measuring high temperatures,but  that can not be used in an oxidizing atmosphere. This patent takes use of the double protection tube  and the perfect combination of special packing structure and the outer and inner layers of .It can prevent oxidation of the high-temperature process of using osmotic mini,at the same time  eliminate residual oxygen packing microporous and silk gap.So that can ensure the long-term use of tungsten-rhenium thermocouples in the oxidation of the atmosphere . While using the structure and techniques of this patent, we useboth inside and outside protective tube of different materials  and  different fillers.In this way it can widen the range of applications of the tungsten-rhenium thermocouple extending from the ultra-high temperature to the high temperature,from the general medium  to the special medium.  This method not only can partially replace the platinum rhodium thermocouple, but also  can  be applied to special areas which some of the platinum-rhodium thermocouple are unbearable.

Prospects for applications of the technology:
The patented technology  is the  main part of  measuring high temperature. In the high temperature zone  it can replace the expensive platinum-rhodium thermocouple. In ultra-high temperature zone it  is NO.1. Its products can be widely used in metallurgy, machinery, chemical industry, light industry, electric power, petroleum, aerospace, and cement ceramic silicate industrial sector, the market prospect is  so broad.

The analysis of economic benefit :
This patented technology uses raw materials and equipment  in the existing markets, require minimal equipment and don not have waste emissions. This patent is especially suitable for the existing thermal instrumentation manufacturers. Initial investment  can be only a few million. If  it is estimatedf  from  the market share  of a few percent , there are several million dollars of annual profit margins.
