Several Applications of Web Tension Measurement
1. System Description
The DCX is a multi-functional amplifier system that can be configured through its modular design to customized in
-
dustrial application. The individual modules, options and specifications can be individually tailored to fit the specific
applications.
Up to eight force measurement channels can be operate with the amplifier inputs and can be processed with ad
-
ditional process variables.
Averaging, difference calculation or wrap angle correction can be assigned separately to each channel. The signal
processor of the DCX also calculates complex functions in a very short time, eg. the evaluation of the X-Y signals.
The DCX can also be used as a multi-channel web tension controller. Various controller models can be configured
and the control behavior can be modified by winding diameter or the strip speed.
There are analog and digital interfaces available for the signal outputs. On the analog side there are up to eight
voltage outputs available and in addition eight current outputs. On the digital side this is either a fieldbus interface,
such as Profibus or either an Ethernet interface, such as Profinet.
With digital control inputs and outputs, the controller settings can be changed or limit switches can be set.
With the menu-driven touch-panel display, the set up and the use of the DCX is very user friendly.
