Atmospheric Oil Mist Detection Solutions
The QMI Atmospheric Oil Mist Detection System is used to identify oil mist in confined areas such as: engine rooms, pump rooms, bow thrusters, purifier rooms, hydraulic pack areas and test cells.
The equipment uses light scatter (nephelometry) technology. This allows the system to:
- Deliver rapid response within 500 milliseconds of oil mist being detected
- Measure oil mist particles between 3 and 10 microns
- Quantify oil mist in mg/L
- Activate a relay when oil mist is detected
The Atmospheric Sensors are used with QMI Multiplex (12 channel) or QMI Triplex (3 channel) Monitors. The number of Sensors required, will depend on the size of the space being monitored. The atmospheric sample is drawn through the front louvre by the integral fan, through the measuring chamber, then exhausted out of the back of the Sensor.
The Multiplex & Triplex Monitors incorporate a ‘traffic light’ system on each channel to ensure that operators know at first glance if there are hazardous concentrations of oil mist
KEY FEATURES
The Monitor indicates oil mist levels as a percentage of the set alarm limit.
The Monitor can be set to read 100% at 1.3 mg/L and 2.00 mg/L.
For atmospheric applications, we would advise to set the alarm limit at 100% for 0.05 mg/L to ensure the earliest indication of an oil mist release.
Early detection of oil mist helps to safeguard personnel and equipment before a fire occurs. An oil mist release of any size must be treated as a potential fire risk.
