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.
