Model 600
Designed and manufactured in the U.K. by AQM the Model 600 Scattered Light Dust Monitor has particle movement assisted by an integral cyclone.
The Model 600 is designed to take advantage of the phenomena that higher uniform or non-uniform velocities plus accentuated turbulence provide more stray light for the same particle size thereby increasing the instruments sensitivity level.
A typical Model 600 series Dust Monitor has the following items....
A . DRG 1008A Probe Assembly Kit.
B . SU 650 Sampling Unit and connecting 3 way cable. Photo
C . CU 660 Control Unit. Photo
D . DU 670 Display Unit and connecting coaxial cable. Photo
E . DL 672 Datalogger plus software to suit an IBM compatible PC c/w Windows 3.11 or Windows 95
Items A & B to be located within 3 metres of the emission point.
Item C to be located within 100 metres of Items A & B
Items D & E to be located within 1000 metres of Item C and communicate via the co-axial cable using a carrier from Item C with a modulated pulse - repetition frequency. This is a non-standard interface intended to drive Item D only.
Item D processes the signal and presents it in a format that can interface with other equipment.
The Model 600 is suitable for...
Variable velocities
Combustible dusts (to BS 6467)
Dust with high moisture content
High static pressures
Corrosive chemicals
Temperatures above 500 C
The Model 600 offers protection by enclosure for applications such as those to be found in a 'Combustible Dust' environment. The SU Sampling Unit operates on 18 Vdc 50 mA via a protected supply from a dedicated CU 660 Control Unit.
Where the acquisition and downloading of data to computer hard discs is required, AQM offer the DL 672 DataLogger for mounting alongside the DU 670 Display Unit.
For multiple monitoring points at the same site, AQM offer an SC 671 Scanner which automatically scans the signals from up to 8 units and shows the results on a single DU 670 Display Unit.
