Elettrosonda EV
Electroprobe micro controlled, adjustable sensitivity for DIN rail multi-voltage power supply

The electroprobes of the EV, series, produced by MAC 3, are regulators of conductive fluid suitable for the minumum and maximum level control of deep well, tanks, cisterns etc.
The operating principle 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 and subsequently deactivated only when the level descends, uncovering the lower probe.

EV type guarantee the SR type flexibility, the NS type performance
and , moreover, permits:
- to set the relay start time delay 0÷16s
- to select the filling or emptying function.
- to request a realy output with 2 change over contacts in 3 DIN rail version.
