Frequently asked questions

Answers to the most common questions about our products and services

It measures machine-tool spindle growth caused by thermal and centrifugal effects, using a suitable ring as target, with an additional temperature output.

The net span is 500 µm with a 100 µm start offset, giving a 100–600 µm interval from the head.

Do not transfer it automatically. The 250 µm OEM option is a separate configuration and needs performance evidence explicitly covering it.

No. The manufacturer prohibits shortening it. Head, cable and controller form a calibrated system; choose the cable configuration beforehand.

No. Analog update is 64 kHz, while frequency response is 2 kHz. Use frequency response for dynamic-measurement planning.
