Schaller Visatron Oil Mist Detector – Reliable Crankcase Monitoring
What is a Schaller VISATRON Oil Mist Detection System?
The Schaller VISATRON Oil Mist Detection System is a specialized crankcase oil mist detection system used to monitor large marine and industrial engines. Oil mist can develop inside an engine crankcase due to conditions such as excessive friction, bearing overheating, lubrication problems, or mechanical component damage.
The VISATRON system continuously monitors the crankcase atmosphere and detects changes in oil mist concentration. When an abnormal condition is detected, the system provides an alarm to alert engine-room personnel so that the condition can be investigated according to the vessel’s safety procedures.
A reliable marine oil mist detector is therefore an important component of engine safety and condition monitoring for large propulsion and auxiliary engines.

Advanced Oil Mist Detection Technology
The Schaller Automation VISATRON Oil Mist Detection System is engineered for continuous monitoring of oil mist inside the crankcase of large marine diesel, gas, and dual-fuel engines. Its optical detection technology identifies changes in oil mist concentration and provides early warning of abnormal engine conditions.
The system continuously draws crankcase atmosphere through dedicated sampling points to the monitoring unit. This enables rapid detection of localized oil mist formation and gives engine-room personnel valuable warning information for investigating potential mechanical or thermal problems.
Multi-Point Crankcase Monitoring & Fast Response
Schaller VISATRON systems are designed for multi-point oil mist monitoring, allowing different crankcase compartments or sampling locations to be monitored through a centralized detection arrangement. Depending on the model and configuration, the system can accommodate multiple sensors and sampling points for comprehensive engine coverage.
The VISATRON VN2020 and VN301plus product families provide modern monitoring and communication capabilities, while available EX versions are intended for applicable hazardous-area requirements. Alarm and status indications help engineers identify abnormal oil mist conditions and system faults quickly.
Marine Engine Safety, Diagnostics & System Integration
A Schaller VISATRON Oil Mist Detector provides an important layer of protection for large propulsion and auxiliary engines. By detecting abnormal oil mist conditions at an early stage, the system supports timely investigation of potential issues such as bearing overheating, excessive friction, lubrication problems, or component damage.
Modern VISATRON systems can also provide diagnostic information and communication interfaces for integration with vessel monitoring and automation systems, depending on the specific model. Features such as system diagnostics, alarm monitoring, communication interfaces, and remote indication can simplify maintenance and improve visibility of engine safety conditions.
