SPECTO

A wide range of variants

The wide range of variants of the new length gauge generation offers the user a broad spectrum of possible applications. The probes are suitable for production metrology and for multi-point measuring stations as well as for monitoring measuring equipment and as position measuring devices.

Thus, the length gauges can be selected not only in different measuring lengths and connection variants, but also the type of bolt actuation, the interface as well as the accuracy.

  • Accuracy class: ±1.0 µm
  • Pneumatic
  • Measuring length: 12 and 30 mm
  • Axial and radial connection variants
  • 1Vpp and TTL interface

Robustness & Longevity

A high degree of robustness and durability is achieved through well-matched components and a high degree of in-house production.

Minimal Row Width

The ultra-slim design of the length gauges results in a greatly reduced row width. This extends the scope of applications for the user.

Time Saving

Smart production processes and in-stock length gauges result in very short delivery times.
