Abstract

The signalling device contains a body 1 with cover, made of dielectric material, into the side wall of the body there are executed holes for water supply 2 and discharge 3, and into the cover there are executed an air outlet 4 and an opening 5, closed with a cork 6 of dielectric material. On the inside of the cover it is fixed a steel plate. Inside the body it is placed a float-transducer 9, containing a cylindrical body, the foreparts thereof being sealed with cork hemispheres. Into the cork hemispheres there are fixed the electric contacts 11 and 12, connected to the electric circuit, the connection electric wires being brought out through the cork from the hole into the cover, 2/3 of the transducer body volume are filled up with electrically conducting liquid. Onto the external cylindrical surface of the transducer there is fixed a permanent magnet 15, and onto the opposite side thereof - a load 16. Claims: 1Fig.: 2<IMAGE>
