Scales
 
The Magnescale DRO scale range includes three series of scales that can be used, in any combination, with any of the Magnescale DRO displays.
 
 
Magnescale SJ700A
 
Travel: 150mm to 1600mm
Accuracy: +/- 10µm up to 1250mm
Resolution: 5µm
Measuring system: Magnetic (magneto-resistive)
Max response speed: 60m/min
Protection design grade: to IP54
Cable length: 150 to 800mm scales - 3 m, 950 to 1600mm scales - 5m.
 
General purpose, low cost scale series suitable for all types of machine tools in particular milling machines and lathes. Available in measuring lengths from 150mm to 1600mm. Resolution to 5Ám.
 
 
Magnescale GB-ER
 
Travel: 50mm up to 2200mm
Accuracy: +/- 5µm
Resolution: 0.5µm
Reference: One reference mark
Measuring system: Magnetic (Magnescale)
Max response speed: 60m/min
Protection design grade: to IP54
Cable length: Extension cables CE10: 1, 3, 5, 10m
 
The GB-ER scales are ideal for high precision machine tools including grinders and precision lathes. Available in measuring lengths from 50mm to 2200mm Resolution to 0.5Ám, one reference mark.
 
 
Magnescale SL110 - PL20C
 
Travel: 200mm to 2000mm, longer lengths can be supplied in assembly form
Accuracy: +/- 25 + 5µm per metre of travel
Resolution: 10µm
Measuring system: Magnetic (magneto-resistive)
Max response speed: 300m/min
Protection design grade: IP67 (excluding reading head connector)
Cable length: Select 3, 5, 10, 15, 20, 30m armoured or unarmoured
 
The SL110 Digiruler scale has an aluminium spar and requires a separate reading head PL20C. The scale and head are simple to install and are a very cost effective scale system for long travel machines. Resolution to 10Ám.
 
 
Magnescale SL130 - PL20C
 
Travel: 200mm to 30000mm (30m)
Accuracy: +/- 25 + 5Ám per metre of travel up to 7m
Resolution: 10µm
Measuring system: Magnetic (magneto-resistive)
Max response speed: 300m/min
Protection design grade: IP67 (excluding reading head connector)
Cable length: Select 3, 5, 10, 15, 20, 30m armoured or unarmoured
 
The SL130 Digiruler is an exposed tape scale system and requires a separate reading head PL20C. The scale can be used to measure flat or curved surfaces. The high response speed and large head gap tolerance make it ideal for sheet metal working machines such as punch presses. The SL130 is simply applied to a machine using the adhesive tape kit supplied. It is a very cost effective scale system for layout, position and co-ordinate measuring machines particularly those with long travels.
