High-temperature strain gauges


Through its collaboration with Kyowa Electronic Instruments, HBM, a market leader in the field of test and measurement, has launched its new series of KFU strain gauges for high temperatures of up to 350°C.

The KFU strain gauges are the first series of products manufactured by HBM in collaboration with the Japanese manufacturer and this cooperation of two technology leaders has enabled HBM to complement its range of products.

Suitable for structural tests at exceptionally high temperatures, the latest series of KFU strain gauges are pre-wired and come equipped with a 1 m-long, high-temperature protection cable.

Available in grid lengths of 2 mm and 5 mm, as well as in different versions such aas linear, T (with two measuring grids) or R (with three measuring grids) rosettes, depending on the requirements of the application, the KFU strain gauges are also available with temperature responses matched to steel, austenitic steel and aluminium.

This latest series of strain gauges can be used at high temperatures for specified durations: at 350°C for 72 h or at 300°C for 360 h. Typical applications include strain measurements in autoclaves or environments with steam.
