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
