Graduation engravings on control knobs
Precision graduations can be laser-engraved on the following knobs and flanges:
The graduations, consisting of marks and numbers, are available as indicated in the diagram here below.
Order information example
How to order a graduation on a IZP.35 knob with:
- diameter 33 mm
- 60 marks
- graduation type B
- sequence/graduation position type LI
- figures engraved from 0 to 5 for a total of 6 numbers
All the graduations are available for minimum quantities that depend on the size of the knob and on the type of graduation chosen. These quantities are determined during the quotation analysis.
To create graduations on other elements, special graduations, symbols or customizations, please contact the ELESA sales department.
