Description

DDM-2020 Diameter Controller Measurer and Monitor

DDM-2020 Diameter Controller Measurer and Monitor, it is a 2nd generation of instrument for outer diameter measuring & control. Employing the measuring principle of high speed pulsed IR ray combined with high precision CCD sensor and aided by high speed digital image process technique, the gauge features high measurement accuracy, good stability, easy application and maintenance and long service life, high scan rate and excellent dynamic performance.

In the cable production process, the thickness of the insulation layer is jointly controlled by the speed of the tractor and the extruder.

Cable diameter controller DDM-2020 used in cable production line, the controller measures the diameter of the cable in real time, and outputs an analog signal to control the speed of the tractor and extruder, so, the thickness of the insulation layer will be controlled in a setting range.

The display and monitor DSP-4A is for the DDM-20xx diameter monitor.

A complete set of the controller includes a DDM-2020 diameter measuring head, measuring head support and a separate DSP-3A Monitor.

DSP-3S/3D Diameter Remote Display is for DDM-2020, it offers a remote display, the measuring result will be shown on the display.

Application and Features

DDM-2020 Diameter Controller Measurer and Monitor is used for online diameter measurement and control for electric wire and cable, optic fiber cable, tubes and wires. compared with the previous generation products, the 2nd generation controller is characterized by All digital image process technique and dedicated ultra-large scale integrated circuit, which ensure high stability, compact size and low power consumption.

Hardware acceleration, which provides high measuring speed up to 1800 measurements/S and makes it possible to use the Gauge as a lump & neck detector.

Votage output from -10V to +10V can be used for controlling rotating speed or tension of the related driver.

Advanced feedback control system, which improves the control effect.

 

Mouthing position

DDM-2020 Diameter Controller Measurer and Monitor can be mounted front or behind of cooling trough.

When it is mounted front of cooling trough, an optimized controlling effect may be obtained through in-time feedback due to the proximity of the measuring head to the extruder. But at this time the plastic coating is not cured, so the set nominal value must be accordingly.

When it is mounted behind of cooling trough, the measured value is the real diameter of the wire or cable. But the controlling effect is not so good because of large control lag. Be sure to blow dry the tested wire or cable, otherwise the measuring precision will be affected by the water coating around the wire or cable.

In practical using, the nominal value shall be increased appropriately according to the water content of the test object.
