The new Schaller Automation Visatron VN2020 Oil Mist Detector

In 2020 Schaller Automation released a new oil mist detector, the Visatron VN2020. Acting as a successor to the VN115 and VN116 lines of models, it improves many aspects of what made the VN115 and VN116 series great. The VN2020 will be especially for 4- stroke engine marked. The VN301plus replaces VN215/87plus for the 2- stoke marked!

How does the Visatron VN2020 work?

Visatron VN2020 continuously and simultaneously evacuate crankcase atmosphere from each crankcase compartment between two main bearings. The VN2020 use a header-suction tube system for this purpose. The oil mist detector is positioned in the middle between two header-suction-tube sections located on the engine sides; from these sections, single-suction tubes branch off near the compartments. These tubes are considerably thinner than the header-suction tubes and they have a throttling effect. Owing to the large header-suction- tube diameter the vacuum and consequently the sample flow at each suction point remain virtually constant. The arrangement of the detector in the middle of the header-suction tube results in an optimally short sample running time in the tube system.

  • Integrated pressure regulator including water separator

  • No need for scavenging air filters on VN2020- less spare parts required!
  • Negative pressure to be read out directly on measuring head display- no need for u- tube manometer!
  • CANopen and MODBUS RTU signals!
  • New replaceable main cable between measuring head and connection box!
