See the Danger Before It Happens Meet the Daihatsu MD-SX
The Daihatsu MD-SX is a reliable oil mist detector that safeguards diesel engines by providing early warning of overheating and wear.
In the world of diesel engines, whether on land or at sea, safety and reliability are paramount. One of the most critical yet often overlooked threats to engine integrity is the formation of oil mist in the crankcase. This is where the Daihatsu MD-SX steps inoffering a high-precision, low-maintenance solution to detect oil mist before it leads to serious damage.
What Is the Daihatsu MD-SX?
The Daihatsu MD-SX is an oil mist detection system designed to monitor and detect oil mist particles inside a diesel engines crankcase. The presence of oil mist can indicate overheating bearings, worn seals, or internal mechanical failuresall of which pose serious fire and failure risks if left unchecked.
Key Features
1. Non-Invasive Detection
Unlike traditional systems that use forced air or mechanical parts, the MD-SX uses a natural diffusion method combined with optical dispersion to detect mist. This approach ensures fewer moving parts, lower maintenance, and increased reliability.
2. Flexible Installation
The system supports up to 16 sensor units per engine, providing complete coverage. Sensors can be placed according to engine layout, and the modular design allows for easy installation or retrofit to existing equipment.
3. Real-Time Monitoring
A central controller continuously monitors sensor data and displays it via an LCD panel and LED bar graph, while also issuing alarms in the event of rising mist levels. The system features pre-alarm and high-alarm outputs, enabling timely intervention.
4. Durable Construction
Both the sensors and control unit are built for harsh environments, featuring IP55-rated enclosures. The system is engineered to perform reliably in both marine and industrial conditions.
The MD-SX II Upgrade
Daihatsu also offers the MD-SX II, an improved version specifically designed for 4-stroke medium- and high-speed engines. It features a more compact controller and an advanced algorithm that estimates mist levels between fewer sensorsreducing the total number of sensors needed while maintaining accuracy.
Key Enhancements in the MD-SX II:
-
Compact control unit (approximately two-thirds the size of the original)
-
Mist level estimation using interpolation logic
-
Automatic sensor display scrolling
-
Same IP55 protection and optical detection reliability
