Electro-probes with high, low and variable sensitivity to the mounting base. DC and AC power supply, single and dual voltage
The electrical probe is especially interesting because of their small size. Has a dual voltage. The operating principle is based on the detection by the control box; the resistance of the fluid, the level is controlled by means of special probes immersed in the liquid with the longest serving as the common element. When the liquid level inside the container or the three probes gets wet, it activates a relay which is subsequently deactivated only when the level drops, the discovery of the lower probe.
