Model:DSF series High Endurance Strain Gauge
Use:These gauges are designed for fatigue tests, and can reach a fatigue life of over 10 million times at a strain level of ±3000 με.
These
gauges are designed for fatigue tests, and can reach a fatigue life of over 10
million times at a strain level of ±3000 με. Compared to previously (1 million times at ±1500με), these are gauges of exceptionally
high durability.
In aviation and other areas, repeated load tests of large elongation of
composite materials are conducted. However, it had been necessary to adhere a
new strain gauge frequently as a gauge reached its fatigue life. The DSF series
greatly reduces time and cost of adhering gauges.

* Because this strain gauge is not self-temperature-compensated, it is recommended to preliminarily measure thermal output of this strain gauge using a dummy specimen which is made of the same material as the test specimen.
