Mounting the DS900 Series Sensor
Firmly mount the sensor so that the laser is perpendicular to the motion of travel. The accuracy and reliability of your 3D
images relies on the three-dimensional coordinate system defined by the position of the sensor and the movement of
objects that pass within its view.
Description
1 The origin of the X axis is the optical centerline of the sensor projected
onto the Working Section.
2 For best results, movement should be perpendicular to the laser plane.
The device has three (3) threaded M5 holes and can be mounted using 2 or 3 of these holes, either as direct attachment
points using M5 screws, or as through-holes accommodating M4 screws. One of the mounting holes is a 3mm diameter
reference pin hole, provided to ensure accurate location of the unit during initial mounting or replacement. Refer to the
drawings in Dimensions (DS925B) on page 17 for mounting dimensions and hole locations.
Note :
l
See Safely Handling on page 6 for handling precautions that should be observed during mounting.
l
The unit should be mounted such that the laser beam strikes the target surface at right angles. Misalignment
of the unit can result in inaccurate measurements.
