The QMI TRIPLEX™ Oil Mist Monitor is an advanced engine protection system developed to continuously monitor oil mist concentration inside the crankcase of marine diesel engines. By detecting abnormal oil mist levels at an early stage, the system helps prevent catastrophic crankcase explosions, bearing failures, and major engine damage.
The TRIPLEX™ system uses precision optical detection technology to monitor multiple crankcase sampling points. The control unit continuously evaluates oil mist concentration, displays real-time readings, compares them with preset alarm thresholds, and activates alarms whenever unsafe operating conditions are detected.
Its robust industrial design, reliable electronics, and easy maintenance have made the QMI TRIPLEX™ Oil Mist Monitor a dependable safety solution on commercial vessels, offshore installations, and marine power plants.
SM MARINE SERVICE™ supplies new, used, and professionally reconditioned QMI TRIPLEX™ Oil Mist Monitor systems, control units, detector heads, optical sensors, spare parts, repair services, calibration support, and worldwide technical assistance.
The QMI TRIPLEX™ Oil Mist Monitor is a dedicated crankcase monitoring system that continuously measures suspended oil mist particles generated inside marine diesel engines.
When bearings begin to overheat or lubrication problems occur, microscopic oil droplets are produced before serious mechanical failure develops. The TRIPLEX™ system detects these oil mist particles early, giving engineers sufficient time to investigate and correct the fault before engine damage or a crankcase explosion occurs.
The system provides:
The QMI TRIPLEX™ Oil Mist Monitor continuously samples air from designated crankcase locations using optical detector heads.
Inside each detector, a controlled light source passes through the sampled air. Oil mist particles scatter the light, and sensitive photodetectors measure the scattered intensity. The control unit converts this information into oil mist concentration values and compares them with the programmed alarm limits.
If the measured concentration exceeds the warning threshold, the system generates an alarm. If a dangerous concentration is detected, it activates the final alarm output, allowing integration with the vessel's engine protection system for slowdown or shutdown, depending on the ship's safety philosophy.
The control unit also performs self-diagnostics, monitors communication with detector heads, and identifies faults such as detector contamination, cable failures, or processor errors.
A typical QMI TRIPLEX™ Oil Mist Monitor system includes:
