Sacrificial anode generating current monitoring probe

The utility model discloses a sacrificial anode generating current monitoring probe. The probe comprises a sacrificial anode support leg, a Hall sensor component, a watertight cable (5), a fill material (6), an insulating encapsulation casing body (7) and a magnetic shielding outer sheath (8); the Hall sensor component consists of a Hall sensor (2), a magnetic conduction ring (3) and a Hall sensor circuit (4); the magnetic conduction ring is sleeved on the sacrificial anode support leg; the Hall sensor is arranged on an opening of the magnetic conduction ring; the Hall sensor circuit is electrically connected with the Hall sensor; the Hall sensor component is encapsulated in the insulating encapsulation casing body which is sleeved on the sacrificial anode support leg; the magnetic shielding outer sheath covers the insulating encapsulation casing body; one end of the watertight cable is electrically connected with the Hall sensor circuit; the other end thereof extends out of the magnetic shielding outer sheath; and except for the Hall sensor component, the sealing cavity is filled with the fill material. By adopting the Hall sensor component to detect current, the utility model does not damage the structure of the sacrificial anode. Even if the monitoring device goes wrong, the sacrificial anode can normally operate, and the cathodic protection system can not be invalid. The utility model reduces construction cost and safety cost. .
