3DT Adds Allen-Bradley’s PanelView Plus to Options

3DT now offers Allen-Bradley’s PanelView Plus 7 HMI with MicroLogix 1400 PLC as a standard operator console in many of our systems.  While we still offer Maple Systems’ HMI in many products in 3DT’s line, the PanelView Plus 7 goes a step further in enhancing the user interface.  It is built with an aluminum housing, giving the HMI a quality look and feel.  The touch screen also provides a higher resolution, allowing for clearer images on-screen.

The PanelView Plus 7 is a great option for those who use other Allen-Bradley products in their facility with Ethernet/IP communication.  While data logging can be done using Ethernet/IP, the PanelView Plus 7 can also create a CSV file of the system data and store it on a USB drive.  The data stored can provide insight on the system’s productivity and overall status.  Real-time data trends can also be viewed on the PanelView.  The data trend graphs also provide a look back function to view previous system data.

Both options, PanelView Plus 7 and Maple Systems, provide an excellent interface for 3DT’s systems while allowing for different options based on specific needs and budgets.

Principle of the MultiDyne: Gliding Arc Discharge

The MultiDyne system operates using the gliding arc discharge principle.  The electrode arrangement is the key to this type of discharge.  As shown in the diagram, the arc forms at the closest distance between the electrodes.  The electrodes are curved to allow the arc to travel between them while increasing in size.  The arc however does not travel along the electrodes without the assistance of airflow behind it.  The airflow is carefully set to maximize the size of the discharge without prematurely extinguishing the arc.

Principle of the MultiDyne: Gliding Arc Discharge

The other major component to maximizing the gliding arc discharge is the specialized high voltage transformer.  The transformer is a dry, oil free, transformer capable of providing over ten thousand volts.  The transformer also offers safety features.  The first of the safety features is the ability for the transformer to current limit itself in the event of a short circuit.  The other safety feature is a center tap connected to ground, reducing the potential between the high voltage leads and ground to 50%.


Utilizing the MultiDyne, 3DT has been a solution for numerous industries.  Without the need for a separate ground plate, the MultiDyne is easily incorporated into existing or new product lines.  Adjusting the gap, along with product speed, allows for adjustability of the intensity and size of the discharge on the product.  This allows for most products, regardless of material sensitivity, to be treated.  The size of the arc discharge allows for treatment of three-dimensional objects in addition to flat linear applications.

The diagram below shows how adjusting the gap alters the width of the discharge.
