FAQ

Q: FluidLoc vs standard cable?
A: FluidLoc resists oils/chemicals; standard cables degrade faster.

Q: Minimum target size?
A: Ø8.9mm absolute minimum; use Ø13mm for accurate readings.

Q: Can I use this in axial position measurements?
A: Yes, but scale factor changes on shafts <13mm. Reduce gap to minimize error.
