The Graviner Mk6 OMD is an analogue addressable oil mist detection system, capable of monitoring up to 64 detector heads fitted on up to 8 engines. This is achieved without sample pipes and with minimum cabling. Each detector head monitors a single crankspace and is a stand-alone device. When assigned a unique address and supplied with 24V DC it gathers oil mist density data and converts it to a digital signal for transmission via the data cable to the control unit.

Specifications
