WR series industrial platinum rhodium thermocouple, thermocouple and precious metals as temperature measurement sensor, usually with temperature transmitter, controller and display instrument, such as process control system, 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.
Platinum rhodium thermocouple is composed of two different components of the conductor when two ends 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 show thermoelectric potential produced by the thermocouple 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 often because of the need to vary, but they are roughly the same, the basic structure of the usually by hot electrode, insulation sleeve to protect the main components such as pipe and connection box.
Platinum rhodium thermocouple are suitable for all kinds of high temperature circumstance in the process of production, are widely used in powder metallurgy, bright sintering furnace, vacuum furnace, melting furnace, glass, ceramic and industrial salt bath furnaces and furnace temperature.
The main technical parameters of electrical exports: M20x1.
5, NPT1/2 level of accuracy: I, II protection grade: IP65 accidentally wire diameter: Φ 0.
5 nominal pressure: the atmospheric glass thermocouple are typically installed by thermal components, fixtures and junction box and other major parts.
Glass thermocouple can be directly measured various production from 0 ℃ to 1800 ℃ in the range of the surface temperature of the steam and gas medium of liquid and solid.
