ASI Instruments, a leading manufacturer of state-of-the-art level instrumentation for detection and measurement of dry bulk solids, today announced the LaserTrak 200 laser transmitter at MINExpo International 2004, the mining exposition.
Designed for measuring bulk solids at distances of up to 200 feet (60 meters), the LaserTrak 200 uses an extremely small wavelength.
This means it has virtually no beam divergence and can be narrowly focused even over long distances.

Guided wave radar level transmitter for dry solids
ASI Instruments, a manufacturer of state-of-the-art level instrumentation for the detection and measurement of dry bulk solids, has launched the WaveTrak 5200 guided wave radar level transmitter
The 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.
The LaserTrak 200 is housed in a rugged, powder coated aluminium enclosure, rated for IP65 or NEMA 4X, with Class II and III, Division 1 and 2, Groups E, F, G dust ignition proof ratings to FM and CSA.
This ensures operation in a variety of challenging environments.
Stainless steel dust tubes with built-in purge port prevent dust build-up and protect the optical lens from being coated.
"ASI Instruments laser transmitters go far beyond the abilities of other dry bulk level measurement technologies," said Rick Ayers, Vice President of Sales at ASI Instruments.
"No beam divergence means pinpoint accuracy over long distances.
Advanced signal processing software allows the device to adapt to extremely harsh environments.
You can throw dust, vibration, and changing angles at the LaserTrak 200 and it will still accurately provide the crucial measurements you need".
The LaserTrak 200 transmitter takes measurements using a laser with an extremely small wavelength of around 1 micrometer.
This means there is no angle divergence and so the device can be narrowly focused over long distances, ensuring that it does not pick up interference from surrounding objects.
Oblique angles can be measured with pinpoint accuracy.
This allows it to operate within complex vessels, even if they contain internal structures such as ladders or standpipes.
The LaserTrak 200 is also immune to echoes and reflections, providing consistent performance on solids and total immunity to "cone up" and "cone down" variations in the material being measured.
The LaserTrak 200 features an all-digital system architecture that allows the software to perform distance measurements quickly, then dedicate more time for sophisticated signal processing, data analysis, and distance display.
Variable gain allows the LaserTrak 200 to select the best return signal in quickly changing visibility conditions, such as dust, vapours, and materials of different colours.
This is especially useful in underground mines where high dust levels and excessive vibration can render other non-contact technologies inoperable.
Colour compensation corrects for weak or excessive return signals.
Last pulse detection selects true signals from among the many that are reflected from dust clouds, agitator blades, or other obstacles.
The LaserTrak 200 is a stand-alone unit that requires no calibration or special configuration.
It is easily programmed with a Palm or Pocket PC handheld device or a desktop/laptop personal computer.
Portable mounting options allow users to position the laser in any direction.
No safety glasses are required as ASI Instruments uses Class 1 lasers, making the LaserTrak 200 products safe for the human eye.
ASI Instruments LaserTrak 200 laser level transmitters are available for immediate shipment.
Prices start at USD2600.
Delivery is one week from receipt of order.
