SENTINEL ONE STAR BILGE SWITCH

The new bilge switch that solves the age-old problem of water in the bilge. SENTINEL's operation is very simple: when powered, it goes into standby. When the water level reaches the sensors and wets them simultaneously for at least 30 seconds, SENTINEL activates the pump, which will be automatically deactivated after 15 seconds when one of the two sensors is no longer reached by the water. The two sensors in contact with the water are completely isolated, so as to avoid any oxidation process or galvanic currents. The aluminum body of the switch is also electrically isolated. It has no particular positioning problems: its circular shape with fixing to a single central screw allows the instrument to be oriented towards the direction of arrival of the cables (or in any case the one that makes installation easier), also thanks to its three rear thicknesses. On the front of the switch there are three connection points represented by internally threaded brass bushings + (positive pole), – (negative pole) and P (positive pole of the pump). The sensors are made of two AISI 316 stainless steel plates. This very simple shape allows the sensors to be adapted to any type of installation. They can be fixed using plastic ties or by drilling a hole in them, they can be fixed using a screw or glued with silicone. The constraints to be taken into consideration are: the distance between the sensors must not exceed 30cm and the length of the cables from the switch to the sensors must not exceed 15m. The switch does not activate the pump if there are leaks of fuel and oil only.
