Graviner MK7 Oil Mist Detector

• Each detector monitors a single crank space and is an intelligent standalone device
• The detector gathers oil mist density data and converts it to a digital signal for transmission via the data lines in the detector cable to the Control Unit typically mounted on the side of the engine
• Alarm levels and alarm output parameters are configurable from either the Remote Display or a PC connected directly to the Control Unit
• In the event of a local fault, a detector can be isolated without affecting the function of the other Detectors on the engine. The Mk7 system will continue to operate while the faulty Detector is replaced, repaired or maintenance is carried out
• The Mk7 detectors use optical sensing; (light scatter) as it’s detection method and continually monitors the oil mist density in the crank space to which it is connected. In addition, it self-checks for any internal faults by implementing an automatic 24 hour self-test and then identifies any issues which are recorded in the Event Log
• The Control Unit interrogates each detector in turn, identifies the position connected at the Control Unit, the oil mist density value and determines the status of the detector
• The Control Unit can be supplied with or without a control membrane
• The control membrane has coloured LED indication to show the status of the each Detector connected, plus buttons to locally accept and reset alarms and isolate and de- isolate Detectors if required
