Abstract
The invention discloses a water temperature sensor or a water level sensor, and in particular relates to a sensor which is used on a solar water heater and is used for detecting water in a water tank. The invention aims at overcoming deficiencies in the prior art and provides a stepless water level sensor capable of detecting the change of the water level in the water tank in a real-time manner. The stepless water level sensor comprises a stainless steel pipe, a conductive silica gel layer, a carbon fiber composite material layer, a waterproof insulator, an upper electrode leading-out wire contact, a lower electrode leading-out wire contact and the like. The stepless water level sensor has the characteristics of simple structure, low cost, convenience for use and the like.
Description
Technical field
The present invention relates to a kind of level sensor, especially a kind of what sensor for detection of Water in Water Tanks as using on the solar water heater.
Background technology
The water level and the cooling-water temperature sensor that use now are various in style, a kind of electric pole type water-temperature water-level sensor is disclosed in the patent of patent No. ZL01217122, the water level of the detection described in this patent has level relatively, the water level that shows corresponding a plurality of gears on the corresponding display, the level that has such as the similar type such as 20%, 50% shows, can not detect along with the variation of solar water heater water tank middle water level in real time respective change.They only can detect Water in Water Tanks position height, can not measure the volume of concrete Water in Water Tanks, and this fuzzy detection method more and more can not satisfy our requirement, and so fuzzy demonstration tends to cause having washed half, and hot water has not just had.The anxious solution for the treatment of us of this phenomenon.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can detect in real time the stepless level sensor that the Water in Water Tanks position changes.
Stepless level sensor scheme of the present invention is like this design, and it comprises that stainless-steel tube, conductive silicon glue-line, carbon fibre composite layer, water-fast insulator, top electrode are drawn wire joining, bottom electrode is drawn wire joining; Described water-fast insulator coats one deck carbon fibre composite layer along its length direction outside; Described carbon fibre composite layer is arranged in the stainless-steel tube; One end of described stainless-steel tube has the sealing of conductive silicon glue-line, the conductive silicon glue-line is connected with carbon fibre composite layer, water-fast insulator layer, the other end is for drawing line end, be connected by the air guide insulation sleeve between the stainless-steel tube of this end and the carbon fibre composite layer, and the carbon fibre composite layer does not contact with stainless steel inside pipe wall; On the described air guide insulation sleeve gas port is arranged, so that the water vapor in the stainless-steel tube of hollow distributes by this gas port; At the nearly conductive silicon glue-line of described stainless-steel tube end the inlet opening is arranged; The wire terminals of carbon fibre composite layer is connected with insulation course, and described carbon fibre composite layer up and down two ends is provided with that top electrode is drawn wire joining and lower electricity level is drawn wire joining, and this contact is drawn by wire respectively.
Described carbon fibre composite layer is that carbon fibre material, graphitized filamentary material are composited.
Can have a plurality ofly according to above-described inlet opening, and be distributed on the same circumference of stainless-steel tube.
Be provided with the metallic support pipe in wire terminals, described insulation course is connected with the metallic support pipe, also can be provided with Wire sheath at metallic support pipe end, and waterproof is infiltrated.
As preferably, be provided with the temperature sense electronic component in the described water-fast insulator, draw by wire.
According to above-described stepless level sensor, water in the water tank enters from the inlet opening of stainless-steel tube, rising along with water level, the carbon fibre composite layer is as a resistance, this resistance along with water level rising resistance value becomes large, along with what of the height of Water in Water Tanks position or the water yield are respective change be converted into, and show on the display, have simple in structure, cost is low, the characteristics such as easy to use.
