DD series

The DD probe, also known as the Divar probe, is a multi-threshold level detector (1, 2 or 3 thresholds) that uses the resistivity of the liquid (from 0.30 mS to 0.55 mS). This probe can be positioned vertically or horizontally (1 threshold) in a metal or plastic tank (under consultation).
We can also provide the electronic management board in 2 versions: one for an AC power supply and another for a DC power supply.
