Description
Technical field
The utility model relates to a kind of parts of measuring water temperature water level, specifically a kind of water-temperature water-level sensor of waterproof antiscale.
Background technology
In the prior art, for solving the problem of measuring temperature in the water, most of producers adopt temperature detecting resistance, and the accuracy of temperature detecting resistance has also satisfied the needs of producer.But owing to temperature detecting resistance need could accurately be measured in water fast as far as possible, so the waterproof measure of temperature detecting resistance just should notice emphatically that as the temperature detecting resistance that contacts with water, general disposal route is directly to encapsulate with epoxy resin; For solving the problem of measuring water level in the water, most of producers adopt the electrode point type, but level electrode, the sealing problem of signal wire is perplexing numerous sensor researchers always, again because the breathing capillarity of signal wire, make signal wire by vapour corrosion, resistance increases even corrosion break signal line, directly cause control assembly malfunctioning, China's water quality differs in addition, the quality problem in a lot of areas is very serious, incrustation scale brings a lot of troubles to sensor, and incrustation scale causes the sensor senses water level inaccurate attached on the electrode, so the waterproof antiscale measure of level electrode just should be noted emphatically, as the level sensor that contacts with water, general disposal route is to overlap live electrode with silicone tube, and fluid sealant such as filling silica gel prevents that into water corrodes again, prevent incrustation scale by silica gel sensor or processing of circuit, but because the problem of aging of silicone tube and filling gel, therefore the validity problem of circuit can not solve the waterproof antiscale problem of water-temperature water-level sensor at all.
Summary of the invention
The purpose of this utility model is to overcome the defective that above-mentioned prior art exists, and provide a kind of simple in structure, production cost is low, be easy to processing, the water-temperature water-level sensor that safety coefficient is high.
The technical solution of the utility model is: this kind water-temperature water-level sensor, comprise temperature detecting resistance and level electrode, and it is characterized in that temperature detecting resistance is used as the water level fixed mount, insulation interlayer silicon rubber cup and heat-shrink tube are arranged between level electrode and the fixed mount; Level electrode can be free movable.
The further technical scheme of the utility model is:
The temperature detecting resistance body is placed on outlet and exceeds in one section airtight copper pipe of water level, fills the fluid sealant with copper product expansion coefficient basically identical in the copper pipe.
Between level electrode and the lead-in wire silica gel sheath waterproof interlayer is arranged, and fix, be provided with silicon rubber cup, filling gel in this silicon rubber cup in electrode cap, holding screw, wire bond portion by holding screw.
The beneficial effects of the utility model are, compare with prior art, have reasonable in design, simple in structure, be easy to processing, characteristics such as volume is little, error is little, sensible heat is fast, coefficient height easy to use, safe, thoroughly avoided bringing water-temperature water-level sensor water inlet and incrustation scale to adhere to, thereby caused testing incorrect problem because of the erosion of surrounding medium.Therefore, have good value for applications.Be suitable in all kinds of water-temperature water-level measurement environment.
