NEXiS? CS3G-C 系列擠塑控制器

Introduction

The Proton Products NEXiS? CS3G-C Series of controllers are for use on wire insulation or other extrusion production lines.

NEXiS? CS3G-C Series controllers connect to Proton Products diameter gauges and speed and length gauges for measurement of insulation diameter and line speed respectively. These measurements are then fed into a PI feedback controller whose fully-isolated and floating output may be used to drive insulation extruders or capstan drives.

Insulation diameter is thus actively controlled and kept in tolerance by the NEXiS? CS3G-C controller.

NEXiS? CS3G-C Series controllers also have advanced features such as a large, high-resolution colour LCD screen with resistive touch panel, password protection, product recipe presets, and Single Scan Flaw Detection (SSFD, for detection of insulation lump and neck flaws).

Insulation Diameter Control

Using the Cold diameter only (single DG / DG-k gauge – D variant)

CS3G-image-01

The NEXiS? CS3G-C is connected to the Cold DG / DG-k diameter gauge after the water cooling trough. The Cold diameter measurement is used to control the extruder so that the final insulation diameter is held within tolerance. Since the Cold diameter measurement is located far from the extruder, this control system response time is relatively slow (and dependent on the line speed), but no shrinkage offset is required.

Using the Hot diameter and a user-set shrinkage offset (single DG / DG-k gauge – D variant)

CS3G-image-02

The NEXiS? CS3G-C is connected to the Hot DG / DG-k diameter gauge before the water cooling trough. A shrinkage offset due to cooling is set by the operator and used in conjunction with the Hot diameter measurement to control the extruder so that the final insulation diameter is held within tolerance. Since the Hot diameter measurement is located close to the extruder, this control system response time is relatively fast.

Using both Hot and Cold diameters and an automatically-calculated shrinkage offset (two DG / DG-k gauge – HC variant)

CS3G-image-03

The NEXiS? CS3G-C is connected to the Hot and Cold DG / DG-k diameter gauges before and after the water cooling trough respectively. The shrinkage offset due to cooling is automatically calculated from the Hot and Cold diameter measurements and used in conjunction with the Hot diameter to control the extruder so that the final insulation diameter is held within tolerance. Since the Hot diameter measurement is located close to the extruder, this control system response time is relatively fast and the user does not need to figure out a shrinkage offset.
