Online particle analyser

The POLA 3000 is a system for online particle analysis that integrates a number of different components into one complete unit. The system is based on an image analysis principle and has a charge coupled device built inside the unit. It also has a computer in the form of a chip inside so that no external PCs are required.

All the electronics such as framer grabbers and synchronisation electronics to control feeders for supplying the particles to the POLA 3000 for analysis are also inside the sealed case.

The data outputs can be in the form of RS232 or, more usually, RS485 or RS422 in process situations where data needs to be transmitted long distances. The data is in the industry standard protocol Modbus, thus making it easy to interface with PLC systems that are already on the process line. The whole system is powered by 24 V, thus reducing heat problems associated with high voltages.

Once images of the particles have been acquired, each image is analysed continuously and the data put into database, which can be transmitted to the PLC at regular intervals. There are also four digital outputs that can be used for data transmission and the system is designed to run 24 hours a day, 365 days of the year.
