The Vega universal vibrating level switch for liquids has PNP transistor output. This is independent of the mounting position, it detects the limit level reliably with millimetre accuracy. This can be used as an empty or full detector, as approved overfill protection, dry running protection or pump protection in vessels and pipelines. It is an affordable solution with maximum reliability and safety.
