The external automatic control liquid level liquid temperature sensor of making according to such scheme adopts external structure, the various drawbacks that can effectively overcome underwater sensing and brought.This sensor construction is simple, have anti-oxidation, anticorrosion, anti-aging, non-scaling, highly sensitive, stable performance, long service life, advantage such as applied widely, also be applicable to the monitoring and the control of the liquid temperature liquid level that fills Acidity of Aikalinity or other corrosive liquids simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a float assembly structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, external automatic control liquid level liquid temperature sensor of the present utility model is vertically mounted on tank top, form by outer tube body 1, guide pipe 2, circuit board 6 and float assembly, wherein, guide pipe 2 is positioned at outer tube body 1, and about outer tube body 1, by pyroceram or stainless steel etc. not magnetic conduction but magnetic permeability preferably material make.Circuit board 6 is contained in the outer tube body 1, and it is parallel with guide pipe 2, liquid temperature level monitoring circuit is housed on it, this circuit comprises liquid temperature monitoring circuit parallel with one another and level monitoring loop, wherein, liquid temperature monitoring circuit is made up of diode in series 3 and the thermistor 5 that is positioned at outer tube body 1 bottom, the level monitoring circuit is made up of the resistance 4 and the magnetic red pipe 7 corresponding with the resistance number in parallel of diode in series 3 and 2～10 vertically-arranged arrangements, the link position of magnetic red pipe 7 and resistance 4 are spaced, the outlet position of this circuit is parallel with electric capacity 8, its lead-out wire can adopt 2～4, and leading-out terminal is by signal transmssion line and be used for the Monitoring and Controlling water temperature, the integrated chip of water level connects.Float assembly is by ball float 9, ball lever 10 is formed, ball lever 10 is hollow tubular or solid rod-like, be non-magnetic stainless steel or silica gel material product, fixedly connected with ball float 9 in the lower end, in the bar of upper end magnetic part 11 is housed, the length of this magnetic part 11 is slightly larger than two distances between the magnetic red pipe 7, ball lever 10 is installed in the guide pipe 2, and can move up and down freely along guide pipe 2, ball float 9 adopts stainless steel or plastic material is made spherical or the ellipsoid shape, to reach corrosion-resistant acidproof or alkaline-resisting purpose, make this sensor can be used for the monitoring and the control of water-temperature water-level, also can be used for the monitoring and the control of the liquid temperature liquid level of acidity or akaline liquid.The lower end of outer tube body 1 is a blind end, is used for that the holding circuit plate avoids making moist, burn into is aging, and the top can be provided with dustproof and rainproof cover (not shown), falls in the guide pipe to prevent rainwater or dust, influences the sensitivity that float assembly moves up and down.
The operation principle of this sensor is: this sensor uprightly is installed in the top of solar water container in use, and make the lower end of outer tube body 1 be higher than peak level, ball lever 10 is installed in the guide pipe 2, ball float 9 is bubbled through the water column naturally, and move up and down with the height of water level, the leading-out terminal of circuit board 6 is connected with the integrated chip that is used for Monitoring and Controlling water temperature, water level by signal transmssion line, can carries out work.In draining or when adding water, variation along with cistern water level, ball float 9 drives ball lever 10 and moves up and down, the magnetic part 11 of ball lever 10 upper ends will be connected the loop of or adjacent two magnetic red pipes 7, because the number and the resistance value difference of series resistance 4 in this loop, the signal of the integrated chip of its transmission is difference just, processing and control by integrated chip, just but the SEA LEVEL VARIATION in the instant playback water tank by relevant control components and parts, can be controlled the draining and the Shang Shui of water tank automatically.Because the temperature of water surface air equates substantially with water temperature in the water tank, temperature that thermistor 5 is responded to and water temperature basically identical, thereby the processing by integrated chip also can carry out instant playback to water temperature.Because this sensor has only ball float 9 to contact with water, thereby other position all can not be corroded or fouling, and its life-span is prolonged greatly.This sensor also can be used for the monitoring and the control of liquid temperature liquid level in acidity or the akaline liquid container, as long as adopt acidproof or alkaline-resisting stainless steel or plastic material to make ball float 9 and ball lever 10.
