Alarm System for Oil-Water Separators NivOil® / 230 V AC

Designed for the monitoring of hydrocarbon fluids separators, the alarm device NIVOIL may be connected to 1, 2, or 3 sensors.

  • Hydrocarbon layer thickness sensor to detect when the maximum thickness is reached.
  • Overfill sensor to detect when the fluids are on the highest level; this can occur in case of dysfunction of a filter when a float-valve closes to prevent an overfilling when the level of fluid is too high.
  • Sludge layer sensor to alarm when maintenance is necessary.

The 3 sensors may be connected to any input of the alarm device NIVOIL. Any combination of the sensors can be wired. The instrument recognizes automatically the sensor type. A LED indicates the sensor type on the diagram on the front board. When an input is not wired, the LED is off.The alarm device NIVOIL has a built-in buzzer; it is possible to disable its function by a DIP switch configuration.


  • 3 inputs, for any NIVOIL probes
  • Automatic recognition of type probe
  • 3 relay outputs
  • Audible alarm disable by DIP switch
  • Front system drawing with lightning alarms
  • Wall mounting cabinet, IP 65
  • Intrinsic safety acc.: Ex II (1) G [Ex ia] IIB
  • Certification: BVS 07 ATEX E 090
  • Suspended cable probes with 10 m long cable
