In some special occasions, such as chemical plants, smelters, power plants, cement plants, etc., ordinary thermocouples are extremely vulnerable. Therefore, High temperature thermocouple must be used in these cases. The thermocouple is especially suitable for the temperature of the vulcanized bed, coal mill outlet, primary, secondary wind coal and cement industry. High temperature thermocouples are suitable for high temperature applications in various production processes and are widely used in the oil industry, smelting glass and ceramic industry for temperature measurement. 1, platinum-iridium thermocouple, also known as high-temperature precious metal thermocouple, platinum rhodium has a single platinum rhodium (platinum rhodium 10 - platinum rhodium) and double platinum rhodium (platinum rhodium 30 - platinum rhodium 6), they are used as temperature measuring sensors, usually It is used with temperature transmitters, regulators and display instruments to form a process control system to directly measure or control the temperature of fluids, vapors and gaseous media and solid surfaces in the range of 0-1700 °C in various production processes. Platinum rhodium thermocouple, reliable quality, detection is guaranteed, platinum rhodium is a traditional temperature measuring element, with stable thermoelectric performance, strong oxidation resistance, long-term use temperature of 1600 ° C, short-term use temperature of 1800 ° C. The casing adopts a corundum protective sleeve, and the inner core is a high-purity platinum-ruthenium alloy wire, so that the temperature is high, the temperature is accurate, and the precision is high.
