2.3 Operating Principle
The Laser Meter operates on a time-of flight-principal, comparing the phase shift of the
returned signal with respect to that of the emitted laser. Careful measurement of this
phase shift indicates the time taken between sending the light signal and receiving the
reflection back. This is directly proportional to the distance travelled.
3. Location and Mounting
3.1 Sensor Location
The LM-SD Sensor should be installed so as to give a direct view of the target, unobstructed
by dust, steam, hoses or passers-by. The mounting should be vibration free, as any motion
of the sensor is magnified many times at the laser spot. This is a Class II laser, it should
mounted not to shine directly into the eyes of plant personnel. Direct sunlight into the
detector may cause erroneous readings.
It is best to try to have the target surface normal to the laser beam
