    5.5 FLEX MOUNT (Function HEIGHT) With FLEX¨MOUNT the reference surface will be Teached-In. With respect of its inclination, the sensor is able to calculate the height of objects correctly. This function is recommended for the correct calculation of the height of objects with respect to the reference surface.

    5.6 OBJECT To improve sensitivity to dark objects, the exposure time can be increased. This also changes the measuring repetition time. 5.6.1 Object: Bright (Reflectivity > 18%, white-grey) Exposure time Short (Pulse duration) 5.6.2 Object: Dark (Reflectivity 6…18%, dark grey-black) Exposure time Long (Pulse duration)
  • Page 33 The diagram shows the effects of the median (sample size 5). The filter is used to suppress errors. The output changes after a defined number of samples (sample size/2). The measurement frequency is not affected by this filter, but rather the response time. Moving average The output of the moving average filter is the average of all values found in the array with the defined sample size.
  • Page 34 Number of samples until the correct value will be output: In PRECISION mode HIGH, the distance has to be stable for 2 + 0 samples for the output to show the current value. In precision mode very high, the distance has to be stable for 2 + 16 samples for the output to show the current value.

  • Page 35: Field Of View

    5.8 FIELD OF VIEW The width of the measuring field can be limited with the FIELD OF VIEW function. All measuring values outside the set measuring field are ignored. This is particularly useful if, for example, the measuring field contains an unwanted object that should not be detected. The measuring field is adapted by software so the width of the visible laser beam does not change.

The start and end of the measuring range can be reset with SCALE OUT, reducing the measuring field and changing the calibration curve.

  • Page 48: Functional Principle

    6.2 Functional principle The sensor works on the laser triangulation principle. By means of special optics, a laser beam is enlarged into a line and projected to the surface of the object to be measured. Using the multi-lens system, the reflected light from this laser line is projected onto a matrix.

  • Page 63: Standard Deviation

    Standard deviation The standard deviation is a term from the field of statistics or stochastics and is given in σ (sigma). With the standard deviation it is possible to determine how great the dispersion of values around a mean value is. Broadly speaking, the standard deviation is the average distance of all measured expressions of a characteristic from the mean value.
