HEIDENHAIN upgrades LIDA scale for wide temperature range

July 3, 2008 – Because not all machine or instrument measurement applications operate in the same environment, HEIDENHAIN has expanded its LIDA 400 scales series to include a version that is sure to withstand temperatures that others cannot. This new LIDA 403 scale is now available with glass or glass ceramic (ROBAX, ZERODUR) as its graduation carrier for just this reason as its expansion coefficient makes it especially useful in varying temperatures all the while maintaining high accuracy.

HEIDENHAIN’s LIDA 400 series is traditionally based on a steel scale tape with a grating period of 20 µm. This grating period holds true for the LIDA 403. The standard accuracy grade is ± 5µm with higher accuracies available upon request, covering measuring lengths from 240 to 3040 mm (ROBAX up to maximum of ML 1640 mm).

The scanning head on the LIDA 403 will remain the same as others in the series. There is a reference mark at midpoint (distance-coded now available upon request).

The PRECIMET adhesive film on the rear of the scale will ensure simple mounting.

HEIDENHAIN CORPORATION is the North American subsidiary of DR. JOHANNES HEIDENHAIN GmbH, a leading international manufacturer of precision measurement and control equipment. The product line includes linear scales, rotary and angular encoders, digital readouts, digital length gages, CNC controls and machine inspection equipment.
