Measurement in high temperatures – the right sensors for demanding environments
Carrying out reliable measurements in high temperatures is a challenge that requires specially adapted sensors and robust measurement systems.
Whether the task involves measuring strain, vibrations or forces, both sensors and peripheral equipment must withstand extreme thermal and mechanical stress.
Strain gauges, accelerometers and load cells are available in high-temperature versions that enable accurate measurement results even under the most demanding conditions.
Strain gauges for high-temperature measurements
Strain gauges are used to measure deformation in components, structures and materials. For high-temperature applications, such as in automotive testing, energy production or the aerospace industry, sensors are needed that can withstand temperatures far beyond the 80 °C limit of standard models. Kyowa’s weldable strain gauges and ceramic variants can be used in temperatures up to +950 °C.
These high-temperature sensors are often hermetically sealed and made from corrosion-resistant materials, which also makes them suitable for environments with high pressure or exposure to liquids.

Load cells for high-temperature measurements
Kyowa’s LUXT-A is a compact load cell for measuring tension and compression forces at high temperatures, designed to operate continuously up to +195 °C.
With a diameter of only 28 mm and a height of 34 mm, it’s ideal for installation in tight spaces where traditional sensors won’t fit. Despite its small size, the LUXT-A offers high measurement accuracy with linearity within ±0.5% of the measuring range.
It is particularly suitable for applications such as battery safety testing in electric vehicles, material testing and spring load measurements in high-temperature environments.

Accelerometers for high-temperature measurements
Accelerometers are used for vibration testing and monitoring. In high-temperature environments, piezoelectric accelerometers without built-in electronics (charge-mode) are often used, as electronics would degrade above approximately 125 °C. These sensors can operate at temperatures up to +815 °C and are used in turbines, jet engines, and exhaust systems.
When installing, it’s crucial to choose the right cabling, as signal transmission can otherwise be negatively affected. Special high-temperature cables with good electromagnetic shielding are strongly recommended.
