Abstract
A pressure type liquid level sensor comprises a water tank, a support body and an insulator; the bottom of the water tank is connected with a plate electrode by a waterproof film; the support body is connected to the periphery of the plate electrode; an arc surface electrode is arranged in the support body and is connected with the support body by the insulator; the waterproof film is a heat-resistant plastic thin film; the plate electrode is made of elastic copper alloy; the insulator is made of rubber. The pressure type liquid level sensor has the beneficial effects that the structure is simple, the mounting is convenient, the liquid level in the water tank can be timely monitored in the work process, and happened abnormity can be timely shown, so the damage of the sensor caused by the short circuit between the electrodes is eliminated by the waterproof film, the service life is long and the popularization is easy.
Description
Technical field
The present invention relates to a kind of liquid level sensor, especially a kind of pressure liquid level sensor.
Background technology
World economy and industrial develop rapidly, people and industrial demand more and more higher, automobile becomes the important tool of the daily traffic of people and industrial transport gradually, the power of current automobile is main or provided by internal combustion engine, need in internal combustion engine working process chilled water burnt produce used heat pass, to ensure that internal combustion engine normally runs, usual automobile all can arrange a secondary water tank on cooling water temperature device side, be used for the chilled water be evaporated in supply routine work, provide safeguard to engine health work, in secondary water tank, usually level sensor can be installed, when liquid level in secondary water tank is lower or do not remind driver to add chilled water in time sometimes, engine is avoided to break down because lacking chilled water, cause damage.
Traditional liquid level sensor adopts touch sensor, in time there is no chilled water for subsequent use in secondary water tank, just can send signal remind driver, such mode is easy to the injury of making coupled engines when engine cooling water cooler receives damage, it cannot find liquid level situation of change in advance, can not send signal driver in time.
Therefore the technology being badly in need of a kind of improvement solves above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of pressure liquid level sensor.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of pressure liquid level sensor, comprise water tank, supporter and insulator, described water tank bottom connects plate electrode by waterproof membrane, connects supporter around described plate electrode, described supporter inside is provided with cambered surface electrode, and described cambered surface electrode connects supporter by insulator.
Described waterproof membrane is heat-resistant plastic film.
Described plate electrode material is elastic copper alloy.
Described insulating material is rubber.
The invention has the beneficial effects as follows: structure is simple, easy for installation, can monitor the liquid level in water tank in time in the course of the work, there is abnormal can showing in time, use the waterproof membrane short circuit of having stopped between electrode to cause the damage of sensor, long service life, be easy to promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, water tank, 2, cambered surface electrode, 3, waterproof membrane, 4, plate electrode, 5, supporter, 6, insulator.
Embodiment
A kind of pressure liquid level sensor, comprise water tank 1, supporter 5 and insulator 6, plate electrode 4 is connected by waterproof membrane 3 bottom water tank 1, plate electrode 4 surrounding connects supporter 5, supporter 5 inside is provided with cambered surface electrode 2, cambered surface electrode 2 connects supporter 5 by insulator 6, waterproof membrane 3 is heat-resistant plastic film, plate electrode 4 material is elastic copper alloy, insulator material 6 material is rubber, structure is simple, easy for installation, can monitor the liquid level in water tank in time in the course of the work, there is abnormal can showing in time, the waterproof membrane short circuit of having stopped between electrode is used to cause the damage of sensor, long service life, be easy to promote.
