Product Introduction

The VISATRON® VN115/87 Plus Measuring Head is one of the most trusted sensing units used in the Schaller Automation VISATRON Oil Mist Detection (OMD) System. Installed on medium-speed and low-speed marine diesel engines, it continuously monitors crankcase oil mist concentration and provides an early warning before dangerous conditions develop.

Manufactured by Schaller Automation, Germany, the VN115/87 Plus is designed to detect abnormal oil mist levels that may indicate bearing overheating or other mechanical failures, helping prevent crankcase explosions and major engine damage.
