DO YOU FILL OR EMPTY TANK TRUCKS, SILO TRUCKS OR RAILWAY WAGONS?

During loading and unloading inflammable liquids or solids an explosive gas and dust atmosphere may arise – a single spark can be sufficient to initiate an explosion. To prevent this, the occurring electrostatic charges must be discharged safely.

TIMM’s Grounding Control Devices ensure static electricity is discharged to the ground by a grounding cable and continuously monitor the grounding quality. If there is an interruption of the grounding connection, the filling process will be interrupted immediately.

BENEFITS

  • Prevents manipulation due to object recognition (by measuring the impedance)
  • Opening of the housing during operation in gas hazardous areas is allowed
  • Automatic diagnosis system self-monitors all safety-related functions continuously
  • Due to the cable compensation, it is also possible to connect cables up to 30 m
  • NAMUR-compatible Ex i control output

  • Ensures safe grounding before and during the loading operation
  • For use in gas and dust hazardous areas of zone 1 (equipment category II 2 G) and 21 (II 2 D)
  • Controlled derivation of the static electricity
  • Immediate interruption of the loading operation when unsafe grounding connection consists
  • According to all currently relevant EMC and ATEX directives
  • High functional safety according to EN 61508 / SIL 2 (Hardware-Assessment)
  • Device configuration (e.g. “road tank truck“, “railway tank wagon“) via internal switches
  • Easy adjustment of limit values for object detection to local conditions
  • Continuous self-monitoring of the redundant output signal
  • Additional control output
  • Multicolored LED-display to indicate the operating status, failure diagnosis and object recognition settings
  • Extremely sturdy housing, especially resistant to chemicals and other environmental influences
