7. The use of current-compensated coils for interference suppression
is not allowed in the intrinsically safe area.
8. The insulated sensors must be fitted with the IP68 option or with
caps beyond the insulating position. The caps must be reliably
fixed by plastic clamps.
9. The lines from the MUX to the sensor have a maximum length of:
• 100 meters to the accelerometer,
• 60 meters to the RPM sensors,
• 30 meters to the temperature sensors.
RPM sensors with intrinsic safety:
• Inductive sensor VIB 6.620
• Type: NCN8-18GM40-N0-V1 (Fa. Pepperl & Fuchs)
• Inductive sensor VIB 6.622
• Type: NCB8-18GM40-N0-V1 (Fa. Pepperl & Fuchs)
Temperature probe with intrinsic safety
• Sensor VIB 6.610UKEX
• Type RL-4040-20 (Fa. Rössel Messtechnik GmbH)
