There are many kinds of temperature sensors, platinum-rhodium thermocouple is one of them, which can measure the temperature as high as 1800℃ (short-time measurement). Platinum rhodium thermocouple can be divided into single platinum rhodium and double platinum rhodium. It is a measuring element of a temperature sensor. It usually consists of a hot electrode, an insulating sleeve protection tube and a junction box. The sleeve used for platinum and rhodium is made of special material, followed by corundum tube, which is generally ceramic tube.

Selection of platinum-rhodium thermocouple;

When the measuring temperature is normal at 1000~ 1300℃, it is recommended to use single platinum-rhodium thermocouple, and S-class calibration single platinum-rhodium thermocouple is commonly used. When the measuring temperature is normal at 1200~ 1600℃, it is suggested to use a double platinum rhodium thermocouple (platinum rhodium 30- platinum rhodium 6).

Platinum-rhodium thermocouple is suitable for high temperature occasions in various production processes, and is widely used for temperature measurement occasions such as powder metallurgy, sintering bright furnace, vacuum furnace, melting furnace, glass, steelmaking furnace, ceramics and industrial salt bath furnace.

About our platinum rhodium thermocouple temperature sensor

JCJ 100ZB screw thread fixed temperature sensor, its working elements can be replaced by Pt-Rh thermocouple, copper thermal resistor and DS 18B20. We generally recommend platinum-rhodium thermocouple to measure thousands of degrees of high temperature.

Recently, due to the need of heating in northern cities, the use of our temperature sensors in some boiler rooms has also increased.
