Measuring probe for measuring the electrical potential above the base of liquid containers having cathodic corrosion protection

摘要

The measuring probe for measuring the electrical potential in liquid containers having cathodic corrosion protection comprises an electrode rod disposed in a porous-walled tubular container containing an electrolytic liquid. The essence of the invention is that the electrode tubular container 3 is accommodated in a cylindrical measuring capsule 5 which has side openings 6 at a small distance above the base 5b and which is disposed in turn so that it can be moved axially against the action of a spring 8 in a probe casing 7 which is open at the bottom. The measuring capsule 5 is frictionally joined to the pull wire 9 of a Bowden cable 10 which passes through the probe casing 7 and the measuring capsule 5 and is joined to the electrode rod 1. <IMAGE>
