Discover the Scantron difference in non-contact measurement of diameter
Having a precisely known and controlled diameter is critical to the operation and performance of many products with round cross-sections. An incorrect diameter can affect performance in examples like wires, bushings or pins, and can result in product giveaway and increased production costs where continuous product is sold by length. We can offer diameter measurement for applications of virtually any type, from full online measurement and automated feedback of production to measurement of individual components on the benchtop.
Non-contact measurement of diameter offers many advantages compared to checking with a Vernier gauge:
• Far superior accuracy, reproducibility and repeatability
• Can measure moving product, even at several metres per second
• No operator subjectivity or variation
• Ability to measure in small diameter changes and gaps
• Potential for feedback to a production to regulate the process or even generate alarms or stop production
• The ability to self-calibrate and compensate thermal effects
• Instant display of measured diameter versus tolerances with colour coding or go/no-go signals
• Options for automated data capture, storage, and statistical analysis
• Capacity for interfacing with a PC
Diameter measurement can be performed either in one axis or in two or more axes if ovality/roundness measurement is desired.
Gauges with highly application specific software are available for plastic extrusion, wire measurement, centreless grinding, tools with cutting edges and more. To browse the full range of our scanning laser gauge products for diameter measurement, visit our Laser Micrometers page.
Specialised diameter measurement for steel and metals
For application in harsh environments such as the steel and metals industry, we offer the ContourCheck inline laser light measurement systems. The ContourCheck offers a specialised approach to full online measurement of bars, tubes, rebar, wire rod, profile and more, with the ability to identify rolling defects – even in the harshest of environments.
