The Baumer CombiLyz Conductivity sensor series is faster than comparable sensors available on the market thanks to temperature compensation’s short reaction time. The precise measured value of the conductivity is available within only 15 seconds, as opposed to after 50 seconds as with competitors’ sensors.

The short reaction time is only one of the distinguishing features of the CombiLyz AFI. It also sets new standards when it comes to user-friendliness. The colored touch display enables easy parameterization, and freely definable conductivity areas can be allocated to any display colors, for example, blue for water and red for acid. This way, it can be seen from a distance that medium passes through the pipes at any given moment. The sensor transfers its measured values via a 4…20mA interface with an optional HART protocol.
The AFI5 model is a separated type display and sensor and ideal for cramped spaces and strong vibration conditions.
