VISATRON VN115/87‑EMC – Crankcase Oil Mist Detector for Four‑Stroke Engines

Product Overview

VN115/87‑EMC is an optical oil mist detector manufactured by Schaller Automation (Visatron), engineered for continuous crankcase monitoring on 4‑stroke diesel and gas engines. It measures oil‑mist opacity to detect early‑stage mechanical failure such as bearing wear, overheating or piston damage before crankcase explosion occurs. Enhanced EMC electromagnetic compatibility ensures stable operation in marine and high‑interference power‑plant environments, with pre‑alarm and main‑alarm relay outputs for engine protection systems.
