High Accuracy Laser Transmitter for Dry Bulk Solids

摘要

ASI Instruments, a manufacturer of state-of-the-art level instrumentation for detection and measurement of dry bulk solids, recently announced the Laser-Trak~(TM) 200 laser transmitter at MINExpo International 2004, the mining exposition. Designed for measuring bulk solids at distances of up to 60 m (200 ft), this new transmitter uses an extremely small wavelength. This means it has virtually no beam divergence and can be narrowly focused even over long distances. The device's all-digital design provides speed and accuracy in a compact unit. An advanced timing system and self-correcting signal processing functions allow it to accurately and reliably make measurements in the harshest conditions. The system can select the true signal even in the presence of dust, as is commonly found in silos of coal, plastics, or grain, as well as in underground mines or quarries.
