Visatron VN2020 Oil Mist Detector

The Visatron VN2020 Oil Mist Detector is the successor to the Visatron VN87Plus.

The Visatron VN2020 Oil Mist Detector is the successor to the Visatron VN87Plus. The VN2020 is designed for diesel, gas and dual-fuel engines and can check up multiple measuring points simultaneously via an engine-specific mounting kit for complete monitoring of the crankcase. When the oil mist concentration increases at one of the measuring points, an alarm is triggered. The Visatron VN2020 protects the engine preventively, permanently and reliably, contributing to the safety of operator and machine.

The VN2020 is designed for easy retrofitting of the older Visatron VN87, VN87Plus and VN93 Oil Mist Detectors.

The new, environmentally friendly fuels pose new challenges when it comes to engines and their components. The new Visatron VN2020 is the worlds first explosion-protected oil mist detector that complies with both
