OM70 high-performance laser distance sensors offer an easy solution even for demanding measurement applications. The sensor can be quickly and optimally adjusted to the measurement task via the integrated web interface. The latest interfaces additionally ensure very easy integration.
Find the right solution in only 5 steps:
1) Define the measuring range
In order to achieve the highest precision, the measuring range should be kept as small as possible.
2) Select the sweet spot
For particularly reliable measuring results, measurement should be done in the sweet spot (focus) of the laser.
3) Define the beam shape
To increase the stability of the measured value, it is recommended to use a line beam shape. A point sensor is advantageous for measuring the smallest objects and jumps.
4) Select the laser class
A fast measurement on dark objects requires laser class 2; in all other cases laser class 1 is sufficient.
5) Define the interface
Here you have the choice between two variants: an Ethernet TCP/IP interface with a web interface or a serial interface with a display. Both versions provide an analog output.
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.
The measuring range of the OM70 can be limited within the maximum measuring range limits. Using the display of the line signal in the web interface, an interfering peak can easily be faded out.
The stability of the measured values can also be guaranteed on rough and structured surfaces thanks to the fine line beam shape. Thus, not the structure itself, but the object to be measured can be reliably measured.
The optical distance sensors by Baumer automatically adapt to different object colors and brightness levels by optimizing their exposure time accordingly.This makes them independent in terms of the reflectivity of an object.
With the Ethernet TCP/IP interface integrated in the sensor head and implemented protocols such as Profinet, Modbus TCP and OPC UA, it is possible to simplify the integration and configuration of the devices.
The sweet spot can be selected in any measuring range for optimized reproducibility. The sweet spot is the area in the beam path where the focus of the laser beam is located. This ensures the reduction of optical interference effects and thus the minimization of the measurement error of the local repeatability precision.
An additional switching output offers the possibility to categorize measured values (exceeding / falling below a value). The parameterization of a point or window mode including adjustable hysteresis is available for this purpose.
