LD20: Strain Gauge for High Strain or Compression up to 10 %
The use of the strain gauge LD20 is recommended wherever an extremely high strain or compression can occur (>5 %). The LD20 has a maximum elongation of +/- 100,000 µm/m (+/-10 %) and is attached with 30 mm leads.
Note: In terms of fatigue life, the LD20 exhibits a lower resistance to alternating loads than standard Y series strain gauges.
Maximum Elongation
- Maximum elongation of +/- 100,000 µm/m (+/-10 %).
Well suited for high strain rate measurements
Easy to Install
- Simple installation process and easy handling
Extremely flexible, as the Y Series universal strain gauges
