The Graviner MK6 Oil Mist Concentration Probe is a vital component of the highly reliable Graviner MK6 Oil Mist Detection (OMD) system. Specifically engineered for monitoring the crankcase atmosphere in large diesel, gas, and dual-fuel engines, this probe provides an essential early warning of potential explosive conditions. It operates on the principle of light scattering (nephelometry) to precisely measure the density of oil mist. By continuously sampling the atmosphere within each crankcase compartment, the probe detects minute increases in oil mist concentration, which are often the first indication of engine component overheating or failure. Its robust design ensures dependable operation in the demanding high-temperature environment of an engine room, making it a crucial safety device for preventing catastrophic engine damage and ensuring personnel safety in marine and industrial applications.
