Reliable and reproducible measurements
In practice, object surfaces are rarely ideal for optical distance measurement. This often leads to unreliable, unstable measurements. Being the only laser distance sensors on the market, the OM70 sensors therefore offer different focus ranges for the measuring ranges 70, 140, 250, 600 and 1000 mm. This ensures maximum reliability exactly where it is needed in the application.
You are not sure where you want to set the focus range or need the whole measuring range? Then we recommend the basic-type.
Thanks to the automatic exposure time control and the small laser spot of the OM70 laser point, the robot can be positioned very precisely, for example to install small screws.
The checking of the tire geometry, i. e. measurement of the radial and lateral unbalance, as well as inspection of the sidewalls for dents, constrictions, dents etc. takes place at the end of the manufacturing process.
The OM70 laser line sensors reliably check compliance with the tolerances of the sheet thickness of brushed metal and at the same time perform a double sheet check to prevent machine damage and loss of production.
In timber processing, the OM70 laser line sensor checks the dimensional accuracy of glued laminated timber in order to ensure the required structural loadcarrying capacity of the beam.
Thanks to the large measuring range, the OM70 laser line sensors allow the prevention of stroke defects through the continuous monitoring of the press stroke and of the bottom dead center of the press.
Through the analysis of simultaneous measurements on a steel beam, distortions can be reliably detected. Thanks to the large measuring range, different sizes and shapes can be measured.
All variants of the OM70 sensors deliver very precise results over the entire measuring range. Nevertheless, there are several focus ranges to choose from. In this range the sensors measure even more reliably with demanding targets (e.g. strong colour contrasts up to white-black changes, deep black and porous materials). The standard types with focus range at the back of the measuring range are the right choice when the entire measuring range is required.
If, for example, the dimensional accuracy of objects needs to be checked, a direct tolerance measurement and thus the deviation from the target measurement can be determined directly by teaching a reference.
The noise of the output signal can be reduced by activating filtering, thus increasing the resolution.
The measuring range can be adjusted by the user within the maximum measuring range with the teach-in button, the teach-in line or through the display.
A switching output should switch as soon as a defined measured value exceeds or falls below the set level. For a reliable switching signal, the hysteresis (difference between the switching point and the return switching point) can be parameterized in millimeters in absolute terms. The safe operation of your system is guaranteed, regardless of the position of the object in the field of view.
The optical distance sensors by Baumer automatically adapt to different object colors and brightness levels by varying their transmission intensity and optimizing their exposure time. This makes them independent in terms of the reflectivity of an object. Measurements on objects with a reflectivity of up to 2% are also possible.
