Elettrosonda Z8 -Z11
The electroprobes of the Z series are particularly interesting for their reduced size. The Z11 model has a double voltage supply. Both the Z8 and Z11 models are available in the three versions: normal sensitivity (NS), high sensitivity (AS) and adjustable sensitivity (SR).
The operating principio is based on the detection, on the part of the control box, of the fluid resistance, the level being controlled by means of special probes immersed in the liquid with the longest acting as a common element.
When the level of the liquid inside the container or the well wets all three probes a relay is activated which is subsequently deactivated only when the level descends, uncovering the lower probe.
