Strain measurement in holes

Robust strain probe DSRK with glued strain gauge ensures easy installation with long-term stability. The perfectly harmonized geometry of the sensing head with flat inlet and clamping collar eliminates the risk of damage. The probe is inserted in the borehole in non-stressed condition. Just a few mechanical twists suffice to spread the clamping collar of the sensing head which firmly holds the probe in the optimal position. This will ensure absolute measuring precision.

• Improved machine productivity
  • Maintenance-free, so shorter machine down times
• Improved machine performance
  • Higher operating temperature thanks to elastomer-free design
• Optimized logistics
  • No stocking of replacement devices, thanks to maintenance-free design
  • Measurement of forces of different tie bar diameters with one sensor
• Improved machine capability
  • Aging-resistant measuring signals thanks to the use of bonded strain gages
  • Protection from major damage (overloaded tie bars / damage to tools)
  • Sufficient clamping force
  • Improved process control and regulation
  • Quality control through verification of process parameters
• Cost savings in installation
  • Thanks to factory strain calibration, no further adjustment of the machine parameters necessary in case of sensor replacement
  • Risk-free replacement thanks to robust measuring head
