Extrusion Control
Extrusion control uses real-time diameter or wall-thickness measurements to automatically adjust an extruder or capstan drive, keeping insulation dimensions within spec without manual operator intervention. Proton Products' NEXiS controllers range from the mid-range CS3G-C, for a single extruder driven by one or two diameter gauges, up to the CS5G/CS1000 system, which controls up to two extruders with a full graphical touchscreen interface.
Extrusion Control FAQ's
What's the difference between the CS3G-C and CS5G/CS1000?
The CS3G-C is a panel-mounted, mid-range controller for one extruder or capstan drive using one or two diameter gauges, with a color touchscreen. The CS5G/CS1000 is a rack-mountable system for advanced applications, controlling up to two extruders (single or double-layer insulation) from multiple diameter gauges, with a 14-inch touchscreen PC interface.
What gauges do these controllers connect to?
Proton's DG and DGk series diameter gauges for insulation measurement, and SL/SLR series gauges for line speed.
What control algorithm do they use?
A PI (proportional-integral) feedback controller; the CS3G-C also auto-compensates the P-term based on insulation cross-sectional area, with built-in statistical process control (SPC) to minimize material use.
