FORNITURE NAUTICHE ITALIANE - Sentinel one star [1616770]

Code: 1616770

The new bilge switch that solves the age-old problem of water in the bilge The operation of SENTINEL is very simple: when it is powered it goes into standby mode. The moment the water level reaches the sensors and wets them simultaneously for at least 30 seconds SENTINEL activates the pump, which will be turned off automatically after 15 seconds from the moment one of the two sensors is no longer reached by water. The two sensors in contact with water are totally isolated so as to avoid any oxidation process or galvanic currents. The aluminum body of the switch is also electrically insulated. It has no particular problems with positioning: its circular shape with its attachment to a single central screw allows the orientation of the instrument toward the direction of arrival of the cables (or at any rate the one that makes installation easier), thanks also to its three rear shims. On the front of the switch are three connection points represented by internally threaded brass bushings + (positive pole), - (negative pole) and P (positive pump pole). The sensors consist of two AISI 316 stainless steel plates. This very simple shape gives the possibility to adapt the sensors to any type of installation. They can be fixed by plastic ties or by drilling a hole in them, they can be attached by a screw or glued with silicone. The constraints to be taken into consideration are: the distance between the sensors should not exceed 30cm and the length of the cables from the switch to the sensors should not exceed 15mt. The switch will not activate the pump if only fuel and oil spills are present.Specifications:Supply voltage: 10.5V to 30V(in the range of 16V to 21V is not operational)Standby consumption: 1.5 mASwitchable current: 20 ADelays: 15 seconds to trigger 30 seconds to disarmVoltage drop 0.07V at 20AOperating temperature: -15C to +70CCable length cm 20Package contents:No. 1 electronic bilge switchNo. 2 316 stainless steel sensors mm6.3x80No. 1 self-tapping screw mm 3.9 x 38 (fixing screw)No. 3 brass screws mm 3x6 for fixing the lugs to the instrumentNo. 1 assembly instructions
