How to Select Strain Gages
Selection based on measuring object material and measurement environment
- Strain gages for general stress measurement
- Strain gages for composite materials, printed boards, plastics and rubber
- Strain gages for ultra-small strain measurement (semiconductor strain gages)
- High temperature strain gages
- Low temperature strain gages
- Nonmagnetoresistive gages
Selection based on labor-saving effects
Strain gages with leadwire cable preattached
Since a leadwire cable such as vinyl-coated flat cable is preattached in an appropriate length, these strain gages ensure quick and labor-saving installation. For combinations of strain gages and leadwire cables, refer to individual strain gage descriptions.
Waterproof strain gages
The resin-covered surface makes these strain gages waterproof and require no coating treatment.
Selection based on gage length
| Major Applications | Gage Length (mm) |
|---|---|
| Strain measurement on mortar, concrete, etc. | 30 to 120 |
| Strain measurement on lumber, glass, etc. | 5 |
| Strain measurement on general metals, acryl, etc. | 1 to 6 |
| Concentrated stress measurement | 0.15 to 2 |
| Strain measurement in narrow space | 0.2 to 1 |
| Measurement of quickly-changing strain such as impact-initiated strain | 0.2 to 1 |
Selection based on gage resistance
| Resistance | Applications |
|---|---|
| 60Ω | Bending stress compensation |
| 120Ω | General stress measurement |
| 350 to 1000Ω | Transducers |
