SLDC - Introduction
01
SLDC
Intended to adjust the intake of textile fiber at the entry to the line
X-ray generator
The X-ray generator produces radiation across the material
X-ray sensor
The scintillator measures the residual radiation following absorption by the material
Electrical cabinet
The electrical cabinet contains all of the intelligence of the SLDC
Description
02
Developed by Serel at the request of manufacturers of textile lines
The SLDC GC (Serel Lap Density Control Gauge Controller) is a measurement gauge that uses X-rays in order to adjust the material at the entry point of the textile production line. This results in a considerable improvement in its quality.
Thanks to the density measurement of the material that feeds the card and which is measured by the receiver, the SLDC GC can modulate the speed of the motors at the entry to the card and as a consequence increase the regularity of the product while reducing fiber consumption.
Points Clés
03
Compact
As the transceiver is very compact, the SLDC GC can be mounted on most installations, regardless of whether these installations are either new or existing.
No radioactivity
The system uses an X-ray generator and not a radioactive source. Therefore, it is completely safe when it is switched off.

Options
Electrical cabinet
In order to get the best out of your configuration, Serel provides various different versions of standard electrical cabinets. These are either to measure or are more specific to the needs of the client.
Maximum integration
Serel can also supply the SLDC only as an electrics panel for integration into your own installation.
Motorization of feeders
As an option, Serel can supply a variator as well as a geared motor for the controlling of the feeder cylinders. In this instance, the SLDC GC becomes an “SLDC GC internal drive”.
Remote maintenance
The installation of a remote maintenance PC enables Serel’s engineers to access equipment extremely quickly and thereby minimize any production downtime.
Monitoring console
The SLDC GC can also be coupled to a monitoring console that provides a wide range of information and settings:
• Graph of measurements and speeds
• Product database
• Events history
• Configurable alarm levels
• Statistics
• Report printing
• Links to other computers
