ASI Instruments, represented in Australia by Micromax , has released the EasyTrak XP laser transmitter, designed for measuring dry bulk solids, regardless of the presence of surrounding vapour or moderate dust.
The device is housed in an explosion-proof assembly with screw-on cover for quick and easy access. The dual-compartment design allows users to isolate the wiring and terminations from the sensing elements and internal electronics. Meeting the requirements for use in hazardous areas (FM and CSA - Class I, Division 1 and 2, Groups A,B,C,D), the EasyTrak XP's rugged, powder-coated aluminum enclosure is rated for IP67 or NEMA 4X and DIP ratings.
It can measure virtually any solid surface at any angle, whether grain, plastics, or aggregates. The small wavelength of the laser means a narrower beam with virtually no beam divergence and, therefore, no false echoes. This provides accurate readings even when dealing with challenging circumstances such as measuring inside silo cones and silo chutes or through narrow openings in protective grids.
The EasyTrak XP measures distances from 0.3m to 15m. The precise, pulsed laser diode features virtually no beam divergence and no false echoes. As a result the laser can be directed through spaces, as small as 63.5mm in diameter.
The system is immune to reflections and echoes, thus providing consistent performance on solids and immunity to cone up and cone down variations in the material being measured. It is available in a small, compact enclosure and provides a better alternative to open air radar and ultrasonic devices
The system delivers speed and accuracy in a compact unit. Users are up and running quickly because no calibration or special configuration software is required. The all-digital design has an advanced timing system and sophisticated, self-correcting digital signal processing (DSP) functions.
This provides accurate and reliable measurement of level, distance and position in harsh conditions. The system is able to select true signal in the presence of surrounding noise such as moderate dust or agitator blades. The transmitter's variable gain allows the system to select the best return signal in quickly changing visibility conditions such as vapours, and materials of different colour. Colour compensation corrects for weak or excessive return signals, even at high speeds. Readings can be updated as quickly as three times a second. A stainless steel dust tube prevents dust build-up and protects the optical lens from being coated.
The EasyTrak XP is easily programmed with a Palm or Pocket PC handheld device or a desktop/laptop PC. Convenient, portable mounting options allow users to position the laser in any direction. ASI Instruments uses Class 1 lasers, making the EasyTrak products safe for the human eye. No special safety glasses are required.
