Over the years Schaller Automation has created and supplied the world with a range of different generations of Visatron models. Below you will find some additional Visatron models that have not been mentioned in previous posts. One current generation, the Visatron VN/93 generation, and one model that is now out of production, the Visatron VN/87 EMC. These are the models that had a great impact on Schaller Automations standing in the industry.
The Visatron VN/93 generation consist of: VN 115/93, VN 116/93 & VN 215/93. The VN/93 generation did not replace any of our other oil mist detector generations but was a supplement to the other systems. The VN/93 generation was launched into the market in 1997 and production line stopped in 2019. It is easy to identify the VN/93 generation as this is the only oil mist detector by Schaller Automation that was not in a grey, metallic colour, but white.
VN 115/93 during a high oil mist concentration alarm is indicating that there is oil mist concentration inside the engine. VN 116/93 indicates which side of the installation the oil mist concentration is located in the engine. VN 215/93 indicates which compartment of the engine the high oil mist concentration is located in.
