1. integrated electric contact liquid level liquid temperature measurement sensor;

  • Comprise that stainless steel protection sleeve pipe (4) top expansion segment is screwed on sleeve pipe (4a) outside surface, last sleeve pipe (4a) upper end is provided with end cover (7);

    Stainless steel protection sleeve pipe (4) is provided with a plurality of inlet openings;

    Be placed with the skeleton (3) of installing electrodes (2) in the stainless steel protection sleeve pipe (4), it is characterized in that, said electrode (2) is the many armouring thermocouple electrodes that depth of placement has nothing in common with each other in the stainless steel protection sleeve pipe;

    Be provided with an electric contact (6) on the every armouring thermocouple electrode, and all electric contacts all are positioned at sleeve pipe (4a);

    Above-mentioned electric contact (6) structure is;

    cap (6b) under cap (6a) and the stainless steel on the stainless steel that has been welded respectively on corundum ceramic pipe (6c) upper and lower end;

    Armouring thermocouple electrode (2) outwards passes through last cap and following cap from corundum ceramic pipe (6c);

    Between last cap and the armouring thermocouple electrode insulation course is arranged;

    Liquid in last cap and the stainless steel protection sleeve pipe (4) is electrically connected;

    Following cap and armouring thermocouple electrode are electrically connected;

    The positive pole of armouring thermocouple electrode and negative pole are connected with a millivolt thermometer (10) through first, second contact conductor (8a, 8b) respectively, and second contact conductor is connected to an end of electric contact point fluviograph (11), and the other end of electric contact point fluviograph (11) is connected on the tank body of container (13) after being connected in series power supply (12);

    Above-mentioned armouring thermocouple electrode is for bumping die bed armouring thermocouple electrode.
