Product Introduction

The VISATRON VN215/87 Plus Measuring Head is a critical component of the Schaller Automation Oil Mist Detection (OMD) system. Designed specifically for marine diesel engines, this measuring head continuously monitors oil mist concentration inside the engine crankcase and provides early warning of potentially dangerous operating conditions.

Oil mist formation is often the first indication of bearing overheating, lubrication failure, excessive friction, or internal mechanical damage. Early detection is essential for preventing crankcase explosions and avoiding costly engine repairs.

The VISATRON VN215/87 Plus has become one of the most trusted oil mist detection solutions used onboard merchant vessels, offshore installations, and marine power plants worldwide.

What Is VISATRON VN215/87 Plus?

The VN215/87 Plus is the optical measuring head used within the VISATRON VN87 Plus Oil Mist Detection System.

Its primary function is to:

• Continuously monitor crankcase atmosphere
• Detect oil mist particles
• Measure oil mist concentration
• Generate alarm signals
• Provide early engine protection

The system utilizes advanced optical technology to detect even small increases in oil mist concentration before dangerous conditions develop.

This early warning allows engineers to take corrective action and avoid catastrophic engine failures.

How the VISATRON VN215/87 Plus Works

The measuring head continuously receives sampled crankcase air through the VISATRON monitoring system.

Inside the measuring chamber:

1. Air enters the optical measuring chamber.
2. A light source illuminates the sample.
3. Oil mist particles scatter light.
4. Sensors analyze the scattered light intensity.
5. The system calculates oil mist concentration.
6. Alarm thresholds are continuously monitored.

When preset alarm limits are exceeded, the monitoring unit immediately activates warning alarms and identifies the affected engine section.
