Abstract: the WR series industrial platinum rhodium thermocouple, thermocouple and precious metals platinum rhodium thermocouple as the temperature measurement sensor, usually with temperature transmitter, controller and display instrument, such as process control system, platinum rhodium thermocouple used to directly measure or control in the production of a variety of 0 Fluid over a range of 1800 ℃, steam and gas medium and solid surface temperature.
keywords: platinum rhodium thermocouple, single platinum-rhodium thermocouple, double platinum rhodium thermocouple, s-shaped platinum-rhodium thermocouple, type B platinum-rhodium thermocouple
I'm over here is the thermocouple manufacturers need to contact me thermocouple Zhang Weiqin, 135, 0512, 3780 working principle:

type WR platinum-rhodium thermocouple is composed of two different components of conductor two ends when the synthesis loop, when the two junction temperature is not at the same time, will produce thermal current in the circuit. If the work end of the thermocouple with the reference when there is a difference in temperature, display instrument will be installed by the thermocouple thermoelectric potential of the corresponding temperature value. Platinum-rhodium thermocouple electric hot will grows with the temperature measuring end, it is only with the size of the thermocouple temperature at the ends of the materials and relevant, has nothing to do with the hot electrode length and diameter. The appearance of various platinum-rhodium thermocouple is often due to the actual need and appearance is not the same, but they are roughly the same basic structure, usually by the hot electrode, insulation sleeve to protect the main components such as pipe and connection box. Advantages:

type WR platinum-rhodium thermocouple in the thermocouple series has the highest accuracy, stability, best measure [area wide, long service life, high temperature limit, etc. Is suitable for the oxidation of gas, can also be short term used in vacuum, but does not apply to a reducing gas or containing metal or nonmetal steam situations. Selection mode:

to measure the temperature in the 1000 - normally 1300 degrees it is recommended to use the single platinum-rhodium thermocouple ( Platinum rhodium - 10 Platinum) , measuring the temperature of the normal in 1200 ~ 1600 degrees it is recommended to use double platinum rhodium thermocouple ( Platinum rhodium - 30 Platinum rhodium (6) So are using temperature range can ensure the service life of platinum-rhodium thermocouple. Need to pay attention to different and installation requirements of thermocouple thermometer is not the same. Ordering information: type, specification and scope of heat-resistant, environment, whether or not to bring a installation etc. Our company: thermocouple ( Platinum rhodium - 10 Platinum thermocouple, platinum rhodium - Platinum rhodium thermocouple, single platinum-rhodium thermocouple, double platinum rhodium thermocouple, K type thermocouple, thermocouple, precious metal nickel chrome - Nickel silicon thermocouple) Heat resistance, compensation wire, temperature gauges, etc.
