(57) A sensing and checking system (B) of the safety conditions of tanks of the type comprising
a cathodic corrosion protection apparatus (A), allowing the complete automation of
the sensing activities with an improved checking safety and comprising: a data recognition
and output unit (16), such data including a cathodic protection voltage (Vp) and a
reference value (Vt) of a cathodic protection current, having a recognition storage
(18), a storing recognition code of the tank (1); and a check unit (21), connectable
to said data recognition and output unit (16), apt to record the measured values of
said protection voltage (Vp) and of said reference value (Vt), comprising: a main
storage storing a family of identification codes and the corresponding threshold value
for said protection voltage (Vp); and means for comparing (31) said measured value
with said threshold value.
