Abstract

PURPOSE:To permit easy judgement of a timing for exchanging of an anode bar for corrosion prevetion inserted into a vessel body by detecting the electric current flowed when said anode bar dissolves, comparing the detected value and a set value, and announcing the consumption when it is lower than the set value. CONSTITUTION:A consumption detecting circuit A is connected between the conductor of an anode bar 2 for corrosion prevention and a vessel body 1. The circuit A consists of an electric current detecting circuit 8, an amplifier circuit 9, a comparator 10, and a consumption announcing means 11. The electric current flowed when a magnesium bar dissolves is converted to a voltage by the resistor R1 of the circuit 8. This voltage is amplified by the circuit 9. The comparator 10 compares the amplified voltage with a set voltage value and when said voltage is lower than the set voltage, the circuit outputs a consumption signal. The means 11 constitutued of a light emitting diode is triggered by said consumption signal to generate light.
