Anytime, Anywhere Online Analysis

Time is also money in bulk material industries. The response time to manufacturing errors has to be minimised as much as possible. Haver & Boecker has developed a Haver CPA system for online measurement of dry and free-falling bulk material in a measuring range from 34µm to 25mm. It is called Haver CPA 2-1 ONLINE.

The Haver CPA 2-1 ONLINE is resistant against negative surrounding conditions such as heat, dust and wetness. An integrated cooling cycle system ensures a proven operation even at high temperature operation. An air knife cleans camera and lighting array of dust deposits regularly with an air blast. An absorbent minimises the formation of condensation at high air humidity.

Procedure: The Haver CPA 2-1 ONLINE is ready for continuous measurement. It is connected with a downpipe sampler, which takes samples without any interruption of production. The sampler and CPA device can be activated manually or by a programmable controller with interchangeable memory. The analysis is based on the proven CPA measuring principle: A high-resolution digital line scan camera scans the particles of free-falling bulk materials against the background of an LED-lighting array. Up to 28,000 line scans per second are combined by the CPA software to form an endless data record. The shadow projections are evaluated and displayed in real time (Haver REAL TIME). After measurement the sample is returned to the bulk production quantity.

Due to the GigE camera interface a notebook can be placed at a distance of up to 100m from the analysing process.
