Abstract
The utility model relates to a multipoint suspended water level and water temperature sensor, which is characterized in that four connection lines are led out of a sensor main rod from top to bottom, wherein four suspended switches are connected to the connection lines, and a power line is led out of the top end of the sensor main rod. The multipoint suspended water level and water temperature sensor is not affected by water quality and scale deposit and has the advantages of accurate display, stable performance, simple structure, less component, low manufacturing cost, long service life, and easy popularization.
Description
Technical field
The utility model relates to the floated water-level and water-temperature sensor of a kind of parts of measuring water-level and water-temperature, especially multiple spot.
Background technology
At present, the sensor that is adopted on the market mostly is two kinds of electrode sensor and pressure type sensors greatly.Electrode sensor, though glue bar type sensor to resist incrustation scale play a role easy to crack invading for a long time under the bubble of hot water, the water inlet, thus cause faulty sensor.Show inaccurately in addition because of water quality is different, also as easy as rolling off a log rubber bar is expanded with heat and contract with cold, the flexural deformation not make old bones.Stainless in addition steel hammer is that conductor is subjected to the influence of water quality and easily produces influencing quality and can't stablizing of incrustation scale with water as the sensor of conductive electrode, and short being difficult in life-span promotes.Pressure type sensor, pressure disappears when sun in summer can water heater be in the wrong diagnosis of fluidized state build-up of pressure formula sensor for a long time and be done when boiling, water inlet suddenly, solar water heater is bombing very easily, and is difficult for popularization.
Summary of the invention
In order to overcome the deficiency of existing water-level and water-temperature sensor, the utility model provides a kind of novel multiple spot floated water-level and water-temperature sensor, and it is simple in structure, and dependable performance is stable, and production cost is low, increases the service life.
The technical scheme that its technical matters that solves the utility model adopts is: the floated water-level and water-temperature sensor of multiple spot, it is that four connecting lines from top to bottom of drawing are arranged on the sensor mobile jib, be connected with four suspension switches on the connecting line, there is the power lead of drawing on the top of sensor mobile jib.
Principle: water temperature partly is to come detected temperatures by thermistor, and thermistor is sent to information control instrument and shows water temperature with direct contact water source after resistant to elevated temperatures polypropylene lead is connected encapsulation process.Water level partly is to utilize a plurality of sealed glass suspension switches, and the suspension switch is the implosion guard contact and the Metal Ball of high-temperature-resistant high-pressure-resistant, makes the position contact switch and be put into the different water level point place of water tank and show different water levels after vacuumizing.When a certain suspension switch the time is flooded in water inlet, the suspension switch is because the buoyancy of water effect, switch is upright straight, the interior metal ball is fallen on the contact, make switch conduction, and produce a trigger pip, thereby trigger pip is shown that through control instrument different water level realizations shows the function of accurate water level through lead.Lead is with the lead behind fire resistant polypropylene material and the suspension switch welded seal.
The beneficial effects of the utility model are, the floated water-level and water-temperature sensor of this multiple spot is not subjected to the influence of water quality, incrustation scale, show accurately, and stable performance, simple in structure, element is few, and cost of manufacture is cheap, and the life-span is long, easily popularization.
