The RIEGL LD05-HTGF is a laser distance meter based on precise time-of-flight laser range measurement especially suited for demanding applications under critical environmental conditions, i.e. high ambient temperature or hazardous environment. It is additionally optimized for very high target temperatures. It uses state-of-the-art digital signal processing to enable precise distance measurement for complex multi-target situations even under bad visibility conditions. Digitizing the echo signal and subsequent analysis enables multi-target distance measurements. The measuring system consists of an optical head meeting the requirements of the relevant application and a separate electronics box, connected by a duplex glass-fiber cable of variable length with connectors on both sides. • Electronics unit and measuring head can be mounted separately according to requirements resulting from critical environmental conditions • Further improved measurement capability in demanding situations causing poor visibility (rain, dust, fog). • Short infrared laser pulses providing excellent interference immunity • Narrow measurement beam with low divergence for excellent spatial resolution • Measurement to almost any surface regardless of the angle of incidence of the beam and the surface characteristics • Significant enhancement of the maximum range based on predetection-averaging visit our webpage www.riegl.com RIEGL ilf LASER MEASUREMENT SYSTEMS

General Description LD05-HTGF Principle of Operation data i/o control / communication processor transmitter online full waveform analysis analog receiver digital electronics unit Target Transmitter lens Reflection coefficient r Receiver lens optical head An electrical pulse generator periodically drives a semiconductor laser transmitter, emitting infrared light pulses, which are fed into a glass fiber cable. The pulses are guided to the optical head and collimated by the transmitter lens. Part of the echo signal reflected by the target is coupled into the glass fiber cable via the receiver lens...

General Description LD05-HTGF Digitizing the echo signal and analyzing it allows excellent clutter suppression under demanding environmental conditions, i.e., in the presence of dust, smoke or fumes. To meet different application challenges, user parameters as measurement rate, maximum target count (first target only, last target only, all targets) or sensitivity are adjustable. Standard Interfaces: • WEB Interface for configuration via WEB browser Industrial Interfaces: • • Analog output 4 – 20 mA Digital switching output (2x) Optional Infrared Radiation Channel: With this option the LD05-HTGF...

The technical data can be influenced by the environmental conditions to a considerable extent, especially by the following parameters and conditions: • Surface temperature and reflection characteristics of the target • Distance to the target • Angle of incidence of the measurement beam • Optical attenuation of the gases between target and instrument 1) Depending on the surface temperature and the reflection coefficient of the target 2) One sigma @ 5 m range under RIEGL test conditions (except measurements at reflective foil / retro-reflective targets). 3) With self-adapting measurement...
