How to choose between single, dual and triple-axis laser micrometre?
We understand how critical your in-process and off-line measurements are. Our laser micrometres from LaserLinc are ideal for measuring outside diameter, ovality, wall thickness, concentricity, profile and more. The Triton Micrometres allow you to confidently measure and manufacture round products to yield better quality with higher efficiency. With three axes of diameter measurement, Triton micrometres provide as much as 10x more precise average diameter for round and elliptical products.
Now, which micrometre do you need for your application?
As mentioned above, there are three axes for you to choose from, and they all work in different applications. These sets of questions should be considered before purchasing your micrometre:
– What is the shape or profile of the product: round, rectangular, hexagonal, or other?
– What are the smallest and largest diameters (or dimensions) you need to measure?
– If your product is supposed to be round, do you need to know when it is not round?
– How often do you need to check the dimension(s)?
– What are the most stringent engineering tolerances on the products you are measuring?
What is the difference between Single, Dual and Triple Axis?
Single-Axis Laser Micrometres: LaserLinc’s single-axis laser micrometres measure product diameter and position from a single direction. This type offers the most flexibility in application and installation. For round parts, it provides a basic, quick, and straightforward diameter check. While they are a cost-effective solution, they do have limitations in flaw detection, as the laser only examines one side, potentially missing defects on the unseen side. A single-axis laser micrometre is ideal for measuring gaps between parts, length, width, height, position, total indicated runout (TIR), and part deflection.
Common single-axis applications include:
- Multi-strand measurement of magnet wire, monofilament or other multi-die extrusion
- Convoluted and armoured product measurement
- Hot steel
- Stranded wire and wire rope
- Drawn wire
Dual-Axis Laser Micrometres: The dual-axis micrometre offers measurements from two perpendicular directions (X and Y axes). This feature helps in identifying ovality, significant diameter variations, or other issues that a single-axis setup might miss. Opt for a dual-axis micrometre when you require more accurate diameter measurements and need to detect ovality, out-of-round conditions, position, or straightness, especially if the part may shift or vibrate slightly during measurement.
Common dual-axis applications include:
- Extruded products such as insulated wire, cable, hose, pipe, and tubing
- Optical fiber
- Corrugated products such as flexible gas pipe, anaesthesia or respiratory tubing, and pipe
- Multi-strand measurement of magnet wire, monofilament or other multi-die extrusions
- Piece-part inspection
Triple-Axis Laser Micrometre: For even higher accuracy in part measurements, a triple-axis micrometre is the way to go. These systems measure from three different directions, creating a more comprehensive profile of the part. They can assess outside diameter and ovality around almost the entire circumference, outperforming dual-axis units. A triple-axis micrometre is ideal for applications involving automatic closed-loop line control, particularly when the product rotates, vibrates, or lacks stability; maximum precision and flaw detection are crucial, especially for ovality. Triple-axis setups are prevalent in industries where minor shape changes can lead to significant downstream issues.
Common triple-axis applications include:
- Round products
- Clear and translucent products
- In-process (online) applications
- Benchtop (offline) applications
