Generating Calibration Value Based on Tip Parallel Resistance Method
When extending lead wires by several hundred meters or finding accurate calibration values, the tip parallel resistance method is adopted. The parallel resistance Rc can be calculated by the following equation:
Examples of Calibration Strain Value and Resistance
(Rg = 120Ω, gage factor Ks = 2.00)
| Calibration Strain Value ε*1 | Resistance Rc (Approx.) |
|---|---|
| 100 μm/m | 600kΩ |
| 200 μm/m | 300kΩ |
| 500 μm/m | 120kΩ |
| 1000 μm/m | 60kΩ |
| 2000 μm/m | 30kΩ |
*1 : The strain value is output as a negative value.
