Abstract
The utility model discloses a water level and temperature sensor for a solar water heater. The utility model is characterized in that the sensor is provided with an apertured stainless steel tube in which a thermosensitive resistor and a conductor with fluorine-coated layer are installed, and the conductor and the thermosensitive resistor are respectively connected with one transmitter. The utility model has the advantages of novel, unique, artful and reasonable design, simple structure, convenient installation, low cost, easy implementation, hard surface mucosity, scale deposit and little scale deposit affection and reliable performance.
Description
Affiliated technical field:
The utility model relates to sensing technology in the electronic surveying, is a kind of water level, temperature measurement sensing device, specifically, is a kind of sensing device that is used to detect interior water level of solar water heater water tank and water temperature.
Background technology:
Solar water heater is the device that is popular at present.The general metal of several sections mutually insulateds that adopts of the existing water-level and water-temperature sensor that is used for solar water heater is placed on boiler, and the electric action by water connects each section one by one, and segmentation reflects the water level height.This is simple in structure but hot water very easily forms incrustation scale on metal, in case form incrustation scale, contact resistance increases even can not conducting.Another kind of is to place the magnet steel of keeping afloat and sliding up and down along track in water, detects the magnet steel position with several tongue tubes or Hall circuit segmentation, reaction water level height.This structural circuit can not influenced by incrustation scale but magnet steel and track all can produce incrustation scale, and influence is slided and lost efficacy.Also be difficult to withstand high temperatures (the solar water heater sky can reach 180 degree when shining).The signal of above device transmits together with temperature signal, generally needs 4-5 root lead in addition, and it is all convenient inadequately to install.If use ultrasonic wave or pressure sensor can improve manufacturing cost greatly and be difficult to carry out.
Summary of the invention:
The purpose of this utility model is to create and a kind ofly influenced by incrustation scale simultaneously to tolerate high temperature, and is easy for installation, relatively the more inexpensive solar water heater water-level and water-temperature sensor of ultrasonic wave pressure transducer.
Technical solution of the present utility model is: a kind of solar water heater water-level and water-temperature sensor, it is characterized in that: a stainless steel tube with holes is arranged, the conductor of band fluorine coating is housed in stainless steel tube with holes, thermistor also is housed in stainless steel tube with holes, and conductor all is connected with a transmitter with thermistor.
The conductor inner core of the conductor of the band fluorine coating described in the utility model in fluoroplastics, sealing.The conductor of band fluorine coating is the fluoroplastics lead that is converted into the U font.Transmitter is loaded in the plastic casing, and by resin-sealed.The conductor of band fluorine coating is installed on the center of stainless steel tube.
The beneficial effects of the utility model are: novel in design unique, ingenious reasonable, simple in structure, easy for installation, cost is low, easy enforcement, surface be difficult for being stained with sticking, be difficult for producing incrustation scale, also be not subject to the influence of incrustation scale, high temperature resistant, dependable performance.
Below in conjunction with drawings and Examples the utility model is further described:
Description of drawings:
Accompanying drawing is the structural representation of a kind of solar water heater of the present utility model with water-level and water-temperature sensor.
The specific embodiment:
Accompanying drawing has been described an embodiment of the present utility model, in this embodiment, a stainless steel tube with holes 3 is arranged, a conductor 2 is sealed in the fluoroplastics 1 (or get one section fluoroplastics lead be converted into the U font), it is loaded in the stainless steel tube with holes 3 again, the conductor that is covered with fluoroplastic layer 12 that is loaded in the stainless steel tube with holes 3 is erected into to tilt to be placed in the water-heater water tank, and the vertical component of conductor 2 length is suitable with water-heater water tank inner bag diameter.Conductor 2, fluoroplastics 1 and water 4 threes form an electric capacity, conductor 2, water 4 are two utmost points of electric capacity, fluoroplastics 1 are capacitor dielectric, for reducing the conductive resistance of water, so fluoroplastics 1 are installed in the center of the stainless steel tube 3 of many places perforate together with conductor 2, thermistor 5 also is housed simultaneously, and conductor 2 all is connected through lead 6 with a transmitter 7 with thermistor 5.The variation of water level is equivalent to the increase and decrease of a pole plate area of electric capacity in the water tank, is uniformly as long as surround the fluoroplastics 1 of conductor 2, and the variation relation of capacitance and water level is linear.And fluoroplastics 1 are good as the capacitor dielectric performance, can high temperature resistantly reach more than 250 degree simultaneously, that the surface is difficult for being stained with is sticking, be difficult for producing incrustation scale (even a small amount of incrustation scale can be ignored as long as its thickness is not enough to the fluoroplastics medium analogy), and temperature sensor then adopts high-temperature thermistor to be installed in the stainless steel tube.Form a water-level and water-temperature probe with this.With lead 6 electric capacity the two poles of the earth are linked to each other with transmitter 7 with thermistor 5.
The transmitter that transmitter 7 can adopt existing water level, temperature measurement to use, it is that a computer chip is sealed in the epoxy resin.Its function is to convert water level electric capacity and two analog variation amounts of thermistor to data signal, and timesharing absorbs main frame power supply, transmission water-level and water-temperature signal on couple of conductor simultaneously.Encoded again formation standardized digital signal is waited to export.Sensor links to each other with controller through couple of conductor, controller adopts the constant current power supply to sensor, take out water level and water temperature signal simultaneously, timing switch circuit is arranged in the sensor, work as switch connection, code signal is exported through on-off circuit, charges to accumulate electric capacity through diode when switch disconnects supply current, to guarantee the electricity consumption of transmission signal.Realize that power supply and water level, water temperature signal transmit a pair of line and promptly finish.
