Dia Controller

Diameter ControllerMilestone in precision diameter measurement
High-speed diameter measurement and detection of lumps and neckdowns
The gauge heads of the new Dia Controller combine a variety of new technological features for the highest precision and reliability to improve productivity of the production line sustainably.
2,500 measurements per second, all with extremely high single value precision allow for an optimum line control and provide reliable statistical data. The gauge heads measure the diameter of cables with an impressive precision and repeatability. SAI EXTRUMECH offers 3 gauge head models for diverse product diameters.

Integrated display and automatic diameter control in the gauge head
The devices have an integrated LCD display with control panel. This gives the operator the diameter value at one glance, directly at the measuring device. At the control panel the diameter nominal value can be entered and the control module activated. Via line speed or extruder rpm the module controls the diameter automatically to the specified value.

Lump detector function
The high measuring rate of the diameter devices also permits the detection of lumps and neckdowns. With the two-in-one system investment costs are reduced. In addition, there is more space in the line as only one gauge head has to be installed.

Directly integrated in the gauge heads is an universal interface module for all connections such as RS485, RS232, Profibus-DP or alternative industrial field busses such as CANopen, Ethernet/IP, DeviceNet, ProfiNet. In this position it is perfectly protected against dirt, water or mechanical influences during the production.

Gauge head design
The opening of the gauges is twice as big as the measuring range to ensure an easy product feed through. A special feature is the swivel type gauge head. It allows for the gauge head to be easily moved up out of the extrusion line. The measuring heads are open at the bottom to prevent dirt and water from falling into the measuring area. The feeding of the connection cables is protected, directly in the gauge head stand.

W-LAN Interface
The Dia Controller has common interfaces as well as an optional WLAN-interface, which allows for a direct connection to a smart phone or laptop. The W-LAN-interface is used for diagnosis and quality control. Measuring values, trend and statistic data, but also video signals are transferred.
