    Functional Principle, Technical Data Functional Principle, Technical Data Short Description The optoNCDT 1900 uses the principle of optical triangulation, that is, a visible, modulated point of light is projected onto the target surface. The diffuse part of the reflection of this point of light is displayed depending on distance on a position-resolving element (CMOS) by an receiver optic which is arranged to the optical axis of the laser beam in a defined angle.

  • Page 20: Error Influences

    Installation 5.1.2 Error Influences 5.1.2.1 Light from other Sources Thanks to their integrated optical interference filters the optoNCDT 1900 sensors offer outstanding performance in suppressing light from other sources. However, this does not preclude the possibility of interference from other light sources if the objects being mea- sured are shiny and if lower measuring rates are selected.

  • Page 21: Surface Roughness

    Installation 5.1.2.6 Surface Roughness Laser-optical sensors detect the surface using an extremely small laser spot. They also track slight surface unevenness. In contrast, a tactile, mechanical measurement, e.g. using a caliper, detects a much larger area of the measurement object. In case of traversing measurements, surface roughnesses of 5 µm and more lead to an apparent distance change.

  • Page 22: Angle Influences

    Installation 5.1.2.7 Angle Influences Tilt angles of the target in diffuse reflection both around the X and the Y axis of less than 5 ° only have a disturbing effect with surfaces which are highly reflecting. These influences have to be explicitly considered when scanning profiled surfaces. Basically the angle behavior of triangulation is li- able to the reflectivity of the measuring object surface.

  • Page 84: Conversion Of The Binary Data Format

    The sensor continues to deliver measurement values to the RS422 output even while communicating with the sensor. For the data transmission with a PC the MICRO-EPSILON IF2008/PCIE PCI BUS interface card is suitable. This can be connected to the sensor via the PC1900-x/IF2008 interface cable, which is also available as an option. The IF2008/PCIE combines the three bytes for the data word and saves them in the FIFO.

    - features by identical functions for the communication (commands), - provides a consistent transmission format for all MICRO-EPSILON sensors. For C/C++ programmers MEDAQLib contains an additional header file and a library file. You will find the latest driver / program rou- tine at: www.micro-epsilon.com/service/download/...

  • Page 86: Liability For Material Defects

    The liability for material defects is 12 months from delivery. Within this period, defective parts, except for wearing parts, will be repaired or replaced free of charge, if the device is returned to MICRO-EPSILON with shipping costs prepaid. Any damage that is caused by improper handling, the use of force or by repairs or modifications by third parties is not covered by the liability for material defects.
