Particle Detector

Brief Description

The particle detector unit can detect and count the number of particles falling through the detection slit and determine the particle position. The smallest particle that can be measured with this unit is 1mm translucent particles falling through the detection slit. The unit has a detection slit size of 300mm x 150mm.

The unit has an RS232 interface for interfacing with a PC. PC control and monitoring software is supplied with the unit. The unit performs a built-in test at startup. A number of parameters can be controlled from the PC such as sensitivity and particle size. The internal embedded software of the unit can also be reconfigured via the serial interface

The particle detector unit was developed for DEBTECH, a division of DE BEERS.


The particle detector was developed as the key sensing element of a particle classification equipment unit. This is a specialised optical instrument which is custom developed for the client. Key Features: The unit was developed to count a single stream of particles that fall through the detection slit at a speed of less than 2.5m/s. The position of each particle is determined to within ±5 mm. The accuracy of more than 99%.Count particles with diameters from 1mm to 32mm.
