Very-High Speed distance meter
Extremely High-Speed meter for scanner applications
"High Penetration" level meter
Distance meter for High-Temperature targets

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 LD90-3-GF can be equipped with the various digital and analog data outputs frequently used in industry.

The measuring system consists of a lightweight and small optical head and a separate electronics box, connected by a duplex glass-fiber cable with connectors on both sides. Its length can be choosen between 10 m and up to more than 100 m.

• The LD90-3-GF electronics unit can be combined with various optical heads to suit nearly any requirement.
• The optical head contains no electronics and is therefore extremely small, lightweight, inexpensive, high-temperature resistant, and insensitive against electromagnetic or ionizing radiation.
• The optical head can be operated in explosion-endangered areas as well as in high-temperature areas, whereas the electronics box can be remotely installed in a protected area.
• The glass-fiber cable provides galvanic insulation between optical head and electronics box.
• Installation as well as replacement of parts of the system in case of servicing requirements is easy and cost-effective.
