The XLS (Xactum Laser Scan Micrometer) series Laser Gauges represent the latest technological development in laser scanning micrometry, featuring record performance.

With their built-in and very powerful electronics, the XLS micrometers can be used as stand alone, intelligent diameter sensors. When programmed with a dedicated software and completed with external display units and operator panels, they can be the heart of dedicated laser measuring and control systems, for the on-line control of a variety of different products. The XLS micrometers can be directly connected to a PC, PLC or NC via standard ethernet or RS232 or RS485 interface line.

Any electronic unit equipped with such an interface can simply get accurate and fast diameter readings: The user can input the measurement data into his own programme, to perform any specific task. Due to this feature, the XLS gauges are ideal diameter sensors for OEM customers, system integrators or for large scale applications.

Measuring transparent objects
Enabling the Glass-Logic, it is possible to check transparent parts, like glass tube or medical tube.
Single face scanning
It is possible to use 1 mirror face only, to cancel the side dither of the scanning plane: when this option is selected, the scanning rate is reduced to 50Hz or 75Hz

Measurement processing

  • Instant values: simple average over n scans
  • Extreme values: Average, Max, Min over k Instant Values

Measurement modeImages from Blistbuster software

  • Free-Running: it processes continuously groups of k instant values to compute the related Extreme Values
  • On-Command, Single-Shot: after an external command, it processes only 1 group of k instant values to compute the related extreme values. The external command is a rising edge on a digital input or a command message via Ethernet/RS232
  • On-Command, Continuous: during a time interval set by an external command, it processes all the measured Instant Values, to compute their extreme values. The measuring time is set by a logic high level on a digital input and/or by Start/Stop messages via Ethernet/RS232
  • Auto-Sync: like On-Command, Single-Shot, but the measurement is automatically triggered by a valid measurement condition (1 part in the measuring field)
     

The Blistbuster software to detect recurrent surface flaws
The XY sensor software includes the Blistbuster feature that can be very useful to check the diameter smoothness of a continuous product (for instance magnet wire) and to detect a very special type of recurrent flaws, commonly called “Blisters”.
Processing a rather high number of single-scan measurements along the product, it is possible to determine that some of these have been taken just over a local flaw, as the result of such a scan is very different from the average wire diameter and much higher than the single scan repeatability of the gauge itself. An exclusive processing algorithm computes some parameters which are very useful to depict the nonuniformity of the product surface.
As the processing algorithm is based on statistical assumptions, a relatively long section of wire must be checked, including a rather high number of flaws. It is impossible to detect any single flaw or to measure its real dimensions, unless the flaw length is longer than the scanning pitch.
 

The XLS sensors are equipped with pre-loaded software to perform different types of measurements, in several modes, to meet a number of applications. In general the instrument performs just as an Intelligent Sensor, transmitting the measured data to an external device, through the serial ports. The tolerance checking or other more sophisticated features are not included; these are performed by the user's device or by the available dedicated systems.

  • Ground or turned parts
  • Metal tubes and bars
  • Plastic extruded tubes
  • Electric cables and conductors
