At high, low and variable sensitivity fot DIN rail.
The electroprobes of the Q series produced by MAC 3 are regulators of conductive fluid suitable for the minium and maximum level control of deep well, tanks, cisterns etc. The operating principle is based on the detection of the fluid resistance on the part of the control box, 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 and subsequently desactivated only when the level descends, uncovering the lower probe.
