A new series of S/R/B type ceramic precious metal thermocouples is designed for high-precision temperature measurement in high-temperature oxide environments and high-temperature kiln working conditions. Classified as standard precious metal thermocouples with leading measurement accuracy, the product series delivers reliable and stable temperature monitoring for various high-temperature industrial scenarios.
The full series complies with IEC 60584-1:2013 and GB 16839.1 standards. It achieves a basic measurement accuracy of ±1°C and a Class II tolerance of ±1.5°C or 0.25%t. The Type B thermocouple supports a maximum operating temperature of 1700°C, fully meeting high-precision calibration and high-temperature process measurement requirements.
The thermocouple is equipped with a 99% high-purity alumina (Al₂O₃) protective tube and features a ceramic block connection structure. It offers excellent high-temperature resistance, oxidation resistance and corrosion resistance, effectively protecting internal components and extending service life in long-term high-temperature oxide operating environments.
The product supports flexible customization. Conventional outer diameters include 6mm, 8mm and 12mm with customizable total lengths. The thermal wire adopts a standard diameter of 0.5mm, and can be customized to 0.45mm or 0.4mm to optimize cost control. Multiple types are available, including single-point, double-point and multi-point configurations, as well as simplex, duplex and multi-point thermal element options to suit diverse kiln equipment and multi-zone temperature measurement demands.
Featuring high precision, outstanding high-temperature stability, strong environmental adaptability and flexible customization, the ceramic precious metal thermocouple effectively solves common pain points such as inaccurate temperature measurement and poor durability in high-temperature oxidation conditions. It is widely applicable to high-temperature kilns, ceramic sintering, metallurgical heat treatment and other high-temperature industrial fields, serving as an ideal standard temperature measuring and calibrating component for high-temperature production processes.
