Measurement in high temperatures: Choosing the right sensors for demanding environments
Sensors and measurement: Carrying out reliable measurements in high-temperature conditions is a challenge that requires specially designed sensors and robust measurement systems.
Whether the task involves measuring strain, vibrations or forces, both the sensors and peripheral equipment must withstand extreme thermal and mechanical stress.
Strain gauges, accelerometers and load cells are available in high-temperature versions that deliver 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 automotive testing, energy production, or aerospace, standard sensors are not enough. Specialized models are required to withstand temperatures far beyond the 80 °C limit. Kyowa’s weldable strain gauges and ceramic types can be used at temperatures up to +950 °C.
These high-temperature sensors are often hermetically sealed and manufactured from corrosion-resistant materials. That makes them suitable for environments with high pressure or liquid exposure.

Load cells for high-temperature measurements
Kyowa’s LUXT-A is a compact load cell for measuring tension and compression forces at high temperatures. It is designed for continuous operation up to +195°C.
With a diameter of only 28 mm and a height of 34 mm, it is ideal for installation in tight spaces where conventional sensors won’t fit. Despite its small size, the LUXT-A provides high accuracy with linearity within ±0.5% of the measuring range.
It is particularly well-suited 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 typically used, since electronics degrade above approximately 125 °C.
These sensors can operate at temperatures up to +815 °C and are commonly applied in turbines, jet engines and exhaust systems.
When installing, it is essential to choose the right cabling, as signal transmission can otherwise be compromised. Special high-temperature cables with effective electromagnetic shielding are strongly recommended.
