SEA Electronics - Filling of lubricant bottles

The customer

SEA Electronics, SCAIME's partner in Tunisia, is an engineering company specializing in industrial process automation.

SEA designs and implements special machines and production, assembly or packaging lines.

Customer requirement

The customer wanted to modernize two packaging lines of lubricant cans.

The system, based on the analog processing of the weight measurements and the filling management by the PLC, was no longer precise enough:

  • Weight measurements too sensitive to vibrations
  • Architecture responsible for the important and variable response time between the weight measurement and the filling valves control.

Our solution

The packaging line supports the labeling, filling and capping of lubricant bottles.

To improve filling rate and dosing accuracy, SEA has chosen to:

  • Double the bottles filling line.
  • Combine fast-rate pre-dosing based on time, followed by fine dosing based on weight and managed by an eNod4-D dosing controller.


  • 2 stainless steel single point load cells AVX 15kg
  • 2 Dosing controllers eNod4-D PROFINET
  • 1 Siemens S7-1200 PLC
  • 1 HMI Siemens KTP400.


In this architecture, the S7-1200 PLC controls the overall operation of the 2 packaging lines: Pre-dosing by time, labeling and capping bottles.

Each eNod4-D controller supports:

  • The signal processing of load cells, especially digital filtering to overcome vibrations.
  • Complete management of the weight dosing cycle.

Customer benefits

  • The automation architecture with part of the dosing cycle managed by eNod4-D and fast communication via Profinet network optimizes the filling rate.


  • The digital filtering of the weight measurement and the local management of dosing cycle by eNod4-D makes it possible to achieve high precision and repeatability of filling.
