LDS1000 Controller for Laser Diode Sensors
4.0 Specification
The LDS1000 Controller can be used in conjunction with various optical
heads.. The dependent characteristics of the optical head are given in the
individual manuals.
The measurement results can only take on their full meaning in relation to
a unit that represents the value to be measured (distance, angle…). The
controller enables the result to be displayed on the unit that corresponds
to the sensor used.
