What is an Oil Mist Detector?
Oil mist detectors are important devices utilized in engine rooms, especially in vessels and large industrial engines. They indicate the presence of fine particles of oil floating in the air—also referred to as oil mist. The mists might be an indicator of overheating or internal damage to the engine. If they are not rectified early, oil mist might lead to disastrous failure.
Introduction to QMI 457.61.061
The QMI 457.61.061 Multiplex Oil Mist Detector is part of QMI’s advanced range of monitoring solutions, designed for use in tough environments such as marine engines, offshore platforms, and power generation plants. Built with multiplexing capabilities, it allows for monitoring multiple engine crankcase areas simultaneously through one unit, simplifying system design and reducing wiring complexity.
Key Features of the QMI 457.61.061
Multiplex Monitoring System – Able to monitor multiple sensors in different crankcase compartments through a single central controller.
High Sensitivity – Can detect low concentrations of oil mist with accuracy, enabling early warning and preventive action.
Self-Diagnostic Functions – Features onboard diagnostics to detect faulty sensors or system performance disruptions.
Robust Construction – Designed to resist high temperatures, vibrations, and extreme environments common in marine and industrial environments.
Compact & Modular Design – Simple to install in cramped engine rooms or control cabinets, with modular components for rapid maintenance.
Alarm Integration – Includes configurable alarms that may be connected to safety shutdown systems or control room indicators.
How It Works
The QMI 457.61.061 works through optical sensors scanning air that is sucked from crankcase chambers. The sample air is scanned for oil mist concentration. When it goes above a set level, the detector sounds an alarm, providing engineers with an opportunity to check and shut down the systems if required. Its multiplexing function allows a single detector to be used to check multiple compartments, thus greatly boosting efficiency.
Applications
The QMI 457.61.061 is common in a variety of industries because of its dependability and multi-zone features:
Marine Engines – In crankcases of huge ship engines to counter oil mist explosions.
Power Plants – In diesel generators to eliminate sudden downtimes and risks.
Offshore Platforms – Provides safety in distant and risky environments.
Heavy Industrial Machinery – Applicable to factories employing large reciprocating engines.
Why Choose the QMI 457.61.061?
Regulatory Compliance: Complies with international maritime and industrial safety standards.
Cost Efficiency: One unit controls several points, reducing equipment and installation costs.
Peace of Mind: Early warning prevents engine damage, minimizes downtime, and improves operator safety.
