Auto-Grader® - for Complex On-line Production Control
The Auto-Grader® continuously determines the melt flow rate, film purity, and transparency - within seconds on-line with polymer production. Self-optimizing and automatic operation ensures optimum adaptation to the polymer to be tested. All relevant data are stored in a database and can be transmitted to a process control system.
When production changes over to a new charge, the Auto-Grader® allows to exactly determine the time when the product meets the specification. This minimizes the portion of "out-of-specification" material.
State-of-the-art Windows™ software allows visualization of all data on a single monitor. The system is open to expansion for running further on-line measurements, e.g. of
color, haze, density (NIR), etc.
A standard Ethernet port is provided for connection to a modern process control system. An optional serial RS 232 can interface to a host computer for monitoring all data in a control room of the production plant. Alarms concerning the specification limits of the product as well as machine alarms can also be connected to the control room (see also schematic at the bottom of this page).
