Development of a Machine Mounted Respirable Dust Monitor.
NTIS: PB/84-207927 :82 pages
This report encompasses the fabrication of a prototype respirable dust sampler and detector assembly for mining machine-mounted dust monitoring application, the design and fabrication of support electronics, and laboratory testing as defined in Phase I of the work. The hardware was fabricated in accordance with the phase i design and modified to improve the performance and to comply with customer requests. Modifications involved the filter media, electronic flow controller, motorized and manual lift mechanisms for the transitional heads, speed reducer for the filter media transfer drive, a power supply for each geiger-muller tube, and a pressure- sensitive taper roller bracket revision. The functional and environmental testing indicated the prototype hardware functioned within the specified requirements.
