Arm and Line Scanner
ARGON's Equipment
ARGON has 1 x Faro Quantum 2.4 and 1 x Faro Platinum 2.4
For laser scanning ARGON uses a Nikon MMD 100 and MMD 200.
Measurement principle
A mechanical arm is a tactile measurement system. It consists of 4 main segments: the base, two arm segments and the main handle. Each of those is connected with one or more hinges, 7 in total. This allows the main handle to be positioned in virtually every possible direction. Doing so the angle of every hinge is measured. With this information the software can calculate the absolute coordinate of the probe at the end of the main handle.
With a laser scanner attached to the arm it becomes a scanning instrument. The arm is used to measure the position of the laser scanner. The laser scanner itself is then used to scan a geometric object.
Range & Accuracy
Range: Both arms offer a total range of 2.4 m. Bigger objects can be measured by using jump points for different positions
Typical accuracy for tactile measurements: 30µm
Typical accuracy for laser scanning: 0,1-0,2 mm.
Advantages
- Portable and easy to use
- Ability to measure in tight spaces and difficult geometries
- Easy combination of single point measurements and scanned pointclouds
Typical Applications
- Corrosion scanning for the gas-sector
- As-built analysis of smaller structures
