The strain gauges of the KFU series are proven specialists for applications in which high temperatures up to 350°C may occur, even across several days. Typical applications include strain measurements on autoclaves or steam applications.
KFU Strain Gauges: For Temperature Ranges up to +350 °C
The KFU series of strain gauges are the ideal choice for structural tests at exceptionally high temperature conditions rising up to 350 °C (see the details provided below).
KFU strain gauges are already pre-wired and are equipped with a 1-meter-long, high-temperature protection cable. They are available with a 2 mm and 5 mm grid, depending on the requirements of the individual application. Moreover, they are available with temperature adaptations for ferritic steel, austenitic steel, and aluminum. The typical applications include strain measurements on autoclaves or measurements under steam.

- Temperature Range: Up to 72 hours or less at 350 °C or 360 hours or less at 300 °C.
- Available Adhesives: The maximum temperature of 350 °C refers to the pre-wired strain gauges and accessories only; HBM offers the EP310N adhesive which is suitable for applications up to 310 °C. For applications with higher temperatures (up to 350 °C),the PI32 adhesive bond from Kyowa Electronic Instruments Co., LTD. (Japan) can be used.
