PARTICLE & Surface Sciences has released the POLA 3000 online particle monitoring system. It is designed for use in harsh environments and uses an image acquisition technology to analyse free-flowing particles from 40µm to over 40mm.
It has built-in 4mA-20mA loop for controlling external devices such as feeders. It can be directly interfaced into PLC systems via an RS232/RS485/RS422 interface. The microprocessor is enclosed inside the analyser and it does not require hard disc drives or similar computing devices that can be unreliable in a process environment.
The unit is suitable for applications in which there is a need to size particles in a continuous stream. It often replaces traditional sieve-type analysis.
