Most industrial thermocouple products on the market have single temperature adaptation scenarios and narrow measurement ranges, which can only meet low-temperature or medium-high temperature measurement needs, and cannot take into account full-temperature-range working conditions. Enterprises need to configure multiple types of thermocouples according to different production links, resulting in increased equipment procurement costs and inconvenient management. Tungsten-rhenium thermocouples break through the temperature range limit of traditional thermocouples, realizing continuous and stable temperature measurement in the ultra-wide range of -40℃ to 1600℃, with full-scenario industrial adaptability.
In low-temperature industrial scenarios, tungsten-rhenium thermocouples have stable and accurate measurement performance. At the low temperature of -40℃, the alloy material will not produce embrittlement, performance attenuation and signal distortion, and can maintain sensitive temperature sensing and stable thermoelectric signal output. It is suitable for low-temperature constant temperature storage, cold processing, low-temperature reaction and other industrial links, making up for the defect that high-temperature thermocouples cannot adapt to low-temperature working conditions, and realizing accurate monitoring of industrial low-temperature processes.
In medium and normal temperature conventional production scenarios, tungsten-rhenium thermocouples have high measurement accuracy and stable signal. In the range of normal temperature to 700℃, the thermoelectric linearity is good, the data error is small, and the working state is stable, which can fully meet the temperature monitoring needs of conventional chemical production, mechanical processing, food manufacturing and other industries. Its comprehensive performance is better than ordinary economical thermocouples such as K-type and E-type, with stronger stability and higher data accuracy.
In ultra-high temperature industrial scenarios up to 1600℃, tungsten-rhenium thermocouples show unique high-temperature resistance advantages. Ordinary metal thermocouples are prone to melting, oxidation and failure in high-temperature environments above 1000℃, while tungsten-rhenium alloy has ultra-high melting point and high-temperature structural stability, and can work continuously and stably in 1600℃ ultra-high temperature environments. It is widely used in high-temperature industrial scenarios such as metallurgical smelting, furnace calcination, new material high-temperature sintering and thermal power equipment operation.
The ultra-wide temperature range enables tungsten-rhenium thermocouples to realize full-process temperature monitoring of industrial production lines. From raw material low-temperature storage, conventional processing and production to finished product high-temperature sintering and shaping, a single type of tungsten-rhenium thermocouple can cover all temperature measurement links, realizing unified equipment configuration and standardized management. It greatly simplifies the equipment matching process of industrial projects, reduces the types and quantities of spare parts, and improves the standardized level of industrial temperature measurement system construction, which is very suitable for large-scale integrated industrial production projects.
