PLC based on Simatic S7-1200
GraviSys-Co Ex-5 Layer
- Co-extrusion control for 2 .. 5 extruders
- Simatic S7-1200 interfaced to GraviProfi 2408
- µm-control for film lines or kg/m-control for pipe lines
- Start-up of a line in automatic mode with synchronous output to all extruders
Gravimetric vibrational feeder
Series VF
As an alternative to screw feeders we offer a loss-in-weight vibrational feeder with the following advantages.
- a nearly stress free material transport
- uniform flow of material
- as single unit or as part of a blending unit
Analysis of flow behaviour
GraviCheck
The flow meter build up with a scale, gain-in-weight control unit and a PC is able to check the flow of any blender or feeder. Throughput derived in short to long cycles is the output value of the unit. This information provides:
- Control of stability and constancy of flow
- Post processing and documentation of test results on the PC
- Check and calibration of volumetric feeders
