Ultra-Magnescale SR33/34, Sony's latest magnetic technology linear encoder, has been designed and developed specifically for use with CNC machine tools.
New magnetic materials and techniques have been developed to make this magnetic linear encoder capable of operating with a signal period of 40 µm (a claimed world first). In comparison with Sony's established Magnescale encoders (operating with a signal period of 200 µm) the SR33/34 represents a quantum leap in accuracy performance and at the same time provides a contaminate proof measuring system for machine tools. The magnetic incremental measuring principle is resistant to contaminants like oil, water and dust, as well as vibration and shock. In case of temperature fluctuations, the scale's thermal expansion coefficient of 12 x 10-6 will match that of the machine tool - so compensation is not necessary.
The range of available measuring lengths is from 70 to 2040 mm with a choice of accuracy grade of ±3 or ±5 µm. The output signals available are 1 Vp-p analog with signal period of 40 µm or TTL (RS422) signal with a resolution of 0,05 to 1 µm. The scales are capable of response speeds up to 2,5 m/s. The design assures compatibility with current and future control systems.

Maintenance, Test & Measurement, Calibration
Cathodic protection keeps buried and submerged pipelines safe from corrosion, but verifying it traditionally means costly, hazardous manual site visits. Omniflex explains how a retrofit module brings remote monitoring to ageing transformer rectifiers without replacing functional infrastructure.

Maintenance, Test & Measurement, Calibration
Microdieseling is a pressure-induced thermal degradation mechanism in which entrained air bubbles are compressed so rapidly that the surrounding oil ignites, producing soot, varnish and sludge. WearCheck explains how it happens, why the damage varies, and how oil analysis detects it.

Maintenance, Test & Measurement, Calibration
WearCheck ARC division manager, Annemie Willer argues that the greatest threat to effective maintenance is no longer a lack of technology, but the gradual replacement of technical judgement by CMMS compliance, leaving no one owning the machine.

Maintenance, Test & Measurement, Calibration
Nitration is as destructive as oxidation in many engines but far less understood. WearCheck technical manager, Steven Lumley explains how nitrogen oxide gases degrade lubricants, why the process is difficult to detect, and what oil analysis can reveal before damage occurs.
