Series LD90-3

The sensors of the RIEGL LD90-3 series are based on the well-proven principle of time-of-flight measurement of short laser pulses. They can be operated with practically any target surface, i.e. “reflectorless” up to many hundred meters, and up to more than 1000 m with reflecting foil or retroreflectors.

Series LD90-3-GF

The distance and level meter RIEGL LD90-3-GF with glass-fiber coupled optical head makes use of the time-of-flight method to determine the distance of a remote target by measuring the transit-time between transmission and reception of a short laser pulse.

Distance measurements can be performed to both non-cooperative and cooperative targets with high accuracy, interference immunity, and excellent reliability. The serial interface allows communication and operation of the instrument. Furthermore, the RIEGL LD90-3-GF can be equipped with the various digital and analog data outputs frequently used in industry.

The measuring system consists of an optical head and a separate electronics box connected by a duplex glass-fiber cable. The optical head can be operated in exposed environments (like high temperature areas), whereas the electronics box can be remotely installed in a protected area.
