Closed Loop Amplitude Control Sieve Shaker
The Octagon 200CL is a premium electromagnetic 3D sieve shaker built for quality control and accreditation laboratories demanding the highest repeatability. Closed Loop amplitude control holds the set amplitude to within 0.1 mm throughout the entire run. It connects to Endecotts SieveWare software via RS232 — sieve results are digitally logged and reported.


Closed Loop Technology
The Closed Loop system continuously monitors and corrects the set amplitude in real time using feedback control. Deviations caused by variations in material density or sample load are automatically compensated.
Application Areas
Frequently Asked Questions
Closed Loop control means the unit continuously monitors the actual amplitude using real-time feedback and corrects it automatically. The set amplitude is maintained throughout the entire analysis run — deviations caused by different material densities or environmental conditions are compensated automatically. The result: significantly higher test-to-test repeatability.
Endecotts SieveWare is a sieve analysis evaluation and control software that connects to the Octagon 200CL via RS232. It enables PC-based management of sieving parameters, logging of raw data, plotting of particle size distribution curves, and generation of standards-compliant reports.
Choose the Octagon 200CL when high repeatability is mandatory — quality control, accreditation, R&D — when software integration and digital data logging are required, or when 0.1 mm amplitude precision is needed.
Yes. The Octagon 200CL is suitable for both dry and wet sieving. The IP 21 protection rating supports safe use in wet sieving applications.
It holds up to 8 full-height or 16 half-height 200 mm (8 inch) sieves. 100 mm sieves are also supported. Stack height can reach up to 450 mm. The measurement range is 20 µm to 125 mm.
