Thin-film strain gage STF series

dynamic

Fe-Cr-Al alloy gages are designed for the use in the widest operating temperature range. These bondable high-temperature wire strain gages are dedicated for measurements of deformations in the details of machinery and equipment, including jet engines, under static and dynamic loads up to +1150°C temperature range. Sensitive grid of the gage is made of 20…30 um diameter iron-chromium-aluminum alloy wire. Sensitive grid is fixed on the temporary backing, possible in two variants: filter paper or fiberglass-reinforced PTFE. Lead wires are made of ribbon or flat wire with 0.07…0.15 mm diameter. Material of the lead wires correlates with the sensitive grid material and is also iron-chromium-aluminum based.
