After adopting said structure, compared with prior art, the utility model has the following advantages: arrange described testing circuit in nylon mounting box, nylon mounting box is between the second adapter sleeve and the second thermal shrinkable sleeve, compact conformation, simply, simultaneously, when being connected with water tank, only the utility model need be put into water tank snorkel, second adapter sleeve and water tank snorkel are socketed and namely complete installation simultaneously, structure greatly simplifies, comparatively simple with water tank syndeton, and, water tank directly can be ventilated by blow vent, without the need to arranging supernumerary structure again, in addition, second thermal shrinkable sleeve fixing cord, make it to relatively rotate with mounting rod and to cause wearing and tearing, comprehensively above-mentioned, the utility model compact overall structure, simply.
As improvement, one end and the pyrocondensation of mounting rod one end of the first adapter sleeve are socketed, the other end and the electrode tip holder pyrocondensation of the first adapter sleeve are socketed, electrode tip holder is round table-like, round table-like large end is positioned at test rod side, large end is provided with annular protrusion, the diameter of the other end after pyrocondensation socket of the first adapter sleeve is less than the diameter of annular protrusion, due to pyrocondensation socket, so play a significant sealing effectiveness, simultaneously, annular protrusion realizes location to the other end of the first adapter sleeve, and the other end of the first adapter sleeve is hided after annular protrusion, prevent water vapor in water tank from pouring between the first adapter sleeve and electrode tip holder along electrode tip holder surface, and then avoid entering in the passage that passes through for internal wiring in the first adapter sleeve and mounting rod, protect internal wiring, in addition, electrode tip holder is the other end pyrocondensation socket of round table-like first adapter sleeve of being more convenient for, pyrocondensation socket gluing, sealing is effective.
As improvement, as public pole in many test rods is common pole, common pole is positioned at centre, other test rod is outside radial setting around common pole, like this, is being connected side with electrode tip holder, between each test rod, spacing can be nearer, what then electrode tip holder can do is less, i.e. electrode tip holder miniaturization, lightweight, makes the utility model structure more compact.
As improvement, common pole is connected side and is provided with the first thermal shrinkable sleeve with electrode tip holder, take surface level as reference field, first thermal shrinkable sleeve lower end is greater than the distance of lower end to surface level of the shortest test rod to the distance of surface level, like this, because between each test rod, spacing is nearer, first thermal shrinkable sleeve can connect side at electrode tip holder on the one hand and delay to form the materials such as incrustation scale between other test rod and common pole, on the other hand, even if form the materials such as incrustation scale, first thermal shrinkable sleeve can play insulating effect, the materials such as incrustation scale are avoided surprisingly other test rod and common pole conducting to be caused detecting inaccurate, more be conducive to the utility model permanance, the raising of stability and reliability.
As improvement; common pole is the hollow stem of both ends open; in this hollow stem, encapsulating is packaged with temperature sensor; hollow stem is connected with the nut for closing this opening away from the opening of one end of electrode tip holder; temperature sensor is electrically connected with a conductor be electrically connected with testing circuit; this structure makes the utility model have temperature sensing function, and provide structural guarantee to the protection of temperature sensor and the raising of permanance, said structure is also convenient to encapsulating encapsulation temperature sensor simultaneously.

Embodiment
Below the utility model is described in further detail:
The utility model water temperature and level sensor, it comprises testing circuit, mounting rod 1, first adapter sleeve 6, electrode tip holder 2 and the many test rods 3 be connected with electrode tip holder 2, each test rod 3 is electrically connected with testing circuit respectively, mounting rod 1 one end is connected with electrode tip holder 2, mounting rod 1 is socketed with the second adapter sleeve 7 for being socketed with water tank snorkel, second adapter sleeve 7 is provided with blow vent 7.1, mounting rod 1 other end thermal shrinkable sleeve is connected to for by this other end with pass wire 10 from this other end and carry out being close to the second coated thermal shrinkable sleeve 8, the axial limiting between the second adapter sleeve 7 and the second thermal shrinkable sleeve 8 of mounting rod 1 is socketed with a nylon mounting box 9, in nylon mounting box 9, described testing circuit is set.
Second adapter sleeve 7 is cylindrical sleeve, and its left end is provided with the roundlet shell of column of a protrusion, and this roundlet shell of column and mounting rod 1 slidably wringing fit are socketed, and meanwhile, the first half of the left end of this cylindrical sleeve is blow vent 7.1.
One end and mounting rod 1 one end pyrocondensation of the first adapter sleeve 6 are socketed, the other end and electrode tip holder 2 pyrocondensation of the first adapter sleeve 6 are socketed, electrode tip holder 2 is in round table-like, round table-like large end is positioned at test rod 3 side, large end is provided with annular protrusion 2.1, and the diameter of the other end after pyrocondensation socket of the first adapter sleeve 6 is less than the diameter of annular protrusion 2.1.
As public pole in many test rods 3 is common pole 3.1, and common pole 3.1 is positioned at centre, and other test rod 3 is outside radial setting around common pole 3.1; Can certainly be other distributed architecture, such as, each test rod 3 be set up in parallel.
Common pole 3.1 is connected side and is provided with the first thermal shrinkable sleeve 4 with electrode tip holder 2, take surface level as reference field, and the first thermal shrinkable sleeve 4 lower end is greater than the distance of lower end to surface level of the shortest test rod 3 to the distance of surface level.
