A unit procedure is a single function such as classifying, mixing or milling.

An operation is a collection of units preparing elements for the final product, such as bases or coatings.

The control of these operations progresses from basic programmable logic controllers (PLC) to distributed control systems (DCS). A human-machine interface (HMI) is used to give direction to the controlling software. Graphic displays enable the operator or supervisor to give direction or receive information from the operation.

Automation

Automation is the sequencing of valves, motors, pumps, etc. to enable accurate and consistent results so that high quality and productivity are achieved.

Data Acquisition

Data acquisition is the recording of operational parameters for a given procedure. Data is collected in a database for use in performance reports. These reports include alarms, system trends, messages and maintenance information. NETZSCH has designed systems for controlled particle sizing for more than thirty years.
