SCHALLER AUTOMATION VISATRON VN 215/87 Oil Mist Detector, based primarily on the manufacturer’s VN/87 EMC operating manual. The manual explicitly covers the VN 215/87 and VN 215/87-EMC variants.
SCHALLER AUTOMATION VISATRON VN 215/87 – Technical Specifications
| Specification | Details |
|---|---|
| Manufacturer | SCHALLER AUTOMATION |
| Product / Series | VISATRON Oil Mist Detector |
| Model | VN 215/87 |
| Product Type | Oil Mist Detector (OMD) / Crankcase Oil Mist Detector |
| Application | Large diesel engines, particularly marine and industrial engines |

| Air Draft Generation | Integrated air jet pump |
| Sampling Principle | Continuous extraction of crankcase atmosphere |
| EMC Version | VN 215/87-EMC available |
| Typical Engine Application | Medium/high-power diesel engines; especially suitable for engines requiring compartment-specific oil mist detection |
The manufacturer describes the VN 215/87 as a version using a valve box for up to ten individual pipes. This allows the detector not only to trigger an oil-mist alarm but also to identify the compartment associated with the abnormal condition.
Measurement Principle
The VN 215/87 continuously draws atmosphere from the engine crankcase through individual sampling pipes. The extracted air passes through an optical opacity measuring path, where the turbidity caused by oil mist is measured using infrared light. If the oil-mist level reaches the configured alarm threshold, the system generates an alarm.
