Our systems are based on two principles, namely, 

  • RF096 systems with rotating laser sensors; 
  • RF040 systems with multisensor measurement head.

Measurement principles and implemented projects description can be found in ID Measurement Presentation: Inner_Diameter_Measurement_Presentation_eng.​​​​​​​
Main features of 6-point ID Measurement system RF040-65/115 are the following:

  • Measured diameter range, mm      65…115
  • ID measurement accuracy, um     ±25
  • Measurement rate, Hz     2000

The parameters of the system can be changed for a specific task. Minimal diameter that can be measured using this method is 30 mm.

System’s manual is available on our website. As usual, we provide demo software and free SDK.
