Typical Applications

  • Continuous high-resolution measuring of daily circumferential variation of trunks or branches

Advantages

  • Non-invasive installation
  • No disturbance of growth
  • Measuring of daily changes and immediate reactions, e. g. to rain
  • Minimisation of the friction on the bark with Teflon layer
  • Invar steel girth cable with minimal dependence on temperature
  • Measuring range expandable by adjusting of the cable

Limitations

  • Strain-gage caused measuring complexity
