Description
Technical field
The utility model relates to a kind of sensor of measuring water level, especially a kind of U type level sensor of measuring in the solar water heater water tank.
Background technology
What now the level sensor that uses in the solar water container had a pawl formula also has a silica gel formula, and they have merits and demerits separately.They all have a common problem, be exactly serviceable life not long, general 2-3 will change a sensor again owing to be immersed in the hot water and will damage for a long time; The stainless steel material that utilizes that has is made the shell of sensor, make sensor obtain prolonging service time, but maintenance and replacing is inconvenient.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of long service life, U type level sensor simple in structure, easy to maintenance are provided.
U type level sensor of the present utility model is design like this, and it comprises hollow U type metal tube, metal weights piece, a plurality of water level resistance, plain conductor, seal protection sleeve pipe; Described a plurality of water level resistance is connected in series by plain conductor, the metal weights piece is connected by plain conductor with bottom water level resistance, the metal weights piece contacts with U type metal tube bottom, be connected with metal electrode on the described plain conductor, metal electrode is connected with two pipes of U type metal tube by the insulation keeper; Described a plurality of water level resistance, plain conductor are arranged in the seal protection sleeve pipe; Upper end at U type metal tube is provided with sleeve pipe, and anti-sealing enters in the U type pipe.
As preferably, described U type metal tube upper end also is provided with seal, and further anti-sealing enters in the U type metal tube.
As preferably, also be provided with thermal sensing element in the described hollow U type metal tube, and be provided with extension line, in order to measure water level.
According to above-described U type level sensor, it is because U type pipe all is a public electrode, the area of electrode is big, good electrical property, thermal sensing element can have extension line to guarantee the accuracy that detects from arbitrary Guan Zhongjun of U type pipe, simultaneously because U type pipe both ends are sealed, do not need the silica gel filling and sealing, therefore it has long service life, and is easy to use, detects characteristics such as effective.
