Outer/Inner Diameter

These sensors measure the outer diameter of a cylindrical object. Although the measurements referenced here are single axis, measurements with two or more axes are also possible.
Two methods are possible for measuring inner diameters: a thrubeam type measurement instrument and a contact-type measurement instrument.

1D Optical Thrubeam Method
LS Series
LS Series

This method measures a target's outer diameter. Ultra-high-speed sampling also makes it possible to measure both the outer diameter as well as the runout.

Point of selection

  • Stable measurement with ultra-high accuracy
  • Fast, non-contact measurement
  • Measurement of transparent targets possible
LS-7000 Series
Ultra High-Speed Optical Micrometer
LS-7000 Series
2D Optical Thrubeam Method
TM Series
TM Series

This series is capable of measuring a target's inner diameter.
Because the object is captured as with a projector, multi-axis measurement and measurements like circularity are also possible.

Point of selection

  • Measurement possible at multiple points simultaneously
  • Highly stable
TM-3000 Series
High-Speed 2D Measurement Sensor
TM-3000 Series
Contact-Type
GT Series
GT Series

Outer diameter measurements are performed using two sensors. The contact-type system allows for highly accurate measurement.

Point of selection

  • Target selection only determined by solidity
  • High-precision measurement possible
GT2 Series
High-Accuracy Digital Sensor
GT2 Series
