The Schaller VISATRON Oil Mist Detector Type 215/87 is a proven crankcase monitoring system designed to detect hazardous oil mist concentrations in large diesel, gas, and dual‑fuel engines. With decades of field reliability and approvals from major classification societies, it provides essential early‑warning protection for marine propulsion and auxiliary engines.
Schaller VISATRON Oil Mist Detector Type 215/87
The Schaller VISATRON Oil Mist Detector Type 215/87 is part of the globally recognized VISATRON series, used on more than 50,000 engines worldwide for crankcase explosion prevention. Engineered specifically for large marine diesel, gas, and dual‑fuel engines, the 215/87 continuously draws atmosphere samples from each crankcase compartment using a wear‑free air‑jet pump. The system measures oil mist density and triggers alarms when concentrations exceed safe thresholds, enabling early intervention before dangerous conditions develop.
The VISATRON 215/87 features automatic opacity adaptation, ensuring stable and false‑alarm‑free operation even under fluctuating engine loads and RPM. Its optical system is protected by a clean‑air barrier, reducing maintenance requirements and ensuring long‑term accuracy. Designed to withstand vibration levels beyond classification standards, the 215/87 is approved by 11 major classification societies and is widely used in marine propulsion engines, auxiliary engines, and power‑plant installations.
This model is a core component of the Schaller DIEMOS system architecture, offering robust, continuous crankcase monitoring and contributing significantly to engine safety and operational reliability.
