Abstract
The utility model discloses a water temperature and water level sensor arranged in a low position. An inner core of the water temperature and water level sensor arranged in the low position comprises a glass fiber bar (1), a water temperature sensor (2), at least two water level electrodes (3), an inner core head (4) and a small programmable circuit board (PCB) (5), and the glass fiber bar (1) is combined with the small PCB (5) through a simple and practical form enabling installation to be convenient. The water temperature sensor (2) and the water level electrodes (3) are connected onto the small PCB (5), detection of water temperature and water level is achieved, conducting silicon gel and insulation silicon gel are pressed at intervals on the outsides of the glass fiber bar (1), the water temperature sensor (2), at least two water level electrodes (3) and the inner core head (4), and in the manufacture process, a tooling is utilized to tightly clamp the inner core pressed by the silicon gel onto a plastic column head (6) for seal protection.
Description
Technical field
The utility model relates to a kind of sensor, relates in particular to a kind of solar water heater water-temperature water-level sensor.
Background technology
Solar water heater and control instrument are basically increasingly mature in the solar thermal utilization industry, have also obtained development at full speed.Thereby having the solar water heater water-temperature water-level of detection makes the sensor of host-initiated corresponding program bring into play more and more important effect in solar water heater system.The kind of water-temperature water-level sensor mainly contains three kinds of side-mounted, overhead and underneath types by the difference of installation site, and the sensor of underneath type is because there are the shortcoming that serviceable life is long, sensitivity is not high, spillage of material is too much in technique, structure, material cause at present.Simultaneously, the anticorrosive and sealing problem of sensor is also on causing very large impact the serviceable life of sensor.
Summary of the invention
The purpose of this utility model is intended to invent a kind of material, environmental protection, high-performance solar water heater underneath type water temperature-level sensor easy to make, simple in structure and that have good seal performance saved.
To achieve these goals; the technical solution of the utility model is: a kind of underneath type water temperature-level sensor; its inner core comprises glass rod (1); cooling-water temperature sensor (2); at least two level electrodes (3); interior core print (4) and little pcb board (5); glass rod (1) and little pcb board (5) are combined by (4) simple and practical forms easy for installation of interior core print; be connected with cooling-water temperature sensor (2) at little pcb board (5); level electrode (3); realize the detection of water-temperature water-level; simultaneously at glass rod (1); cooling-water temperature sensor (2); at least two level electrodes (3); interior core print (4) is outer respectively with electric silica gel and the interval compacting of insulation silica gel; tightly be stuck on the plastics column cap (6) at the inner core that will suppress with silica gel with frock in the manufacturing process, carry out seal protection.
Interior core print (4) at above-mentioned underneath type water temperature-level sensor respectively has up and down 2 buckles, is used for fixing glass rod (1) and little pcb board (5), at plastics column cap (6) but the end opening, be a kind of structure of buckle.
Underneath type water temperature-level sensor of the present utility model outside is electric silica gel and insulation silica gel interval, when water level rises, water storage contacts with electric silica gel, because the electric conductivity of water, the resistance of sensor internal is also changed, and produce corresponding electric signal, thereby finished the detection of water-temperature water-level.
Description of drawings
Be the structural representation of the utility model underneath type water temperature-level sensor such as Fig. 1.
Be the interior core head structure schematic diagram of the utility model underneath type water temperature-level sensor such as Fig. 2.
Embodiment
As shown in Figure 1; the inner core of underneath type water temperature-level sensor of the present utility model comprises glass rod (1); cooling-water temperature sensor (2); at least two level electrodes (3); interior core print (4) and little pcb board (5); glass rod (1) and little pcb board (5) are combined by (4) simple and practical forms easy for installation of interior core print; be connected with cooling-water temperature sensor (2) at little pcb board (5); level electrode (3); realize the detection of water-temperature water-level; simultaneously at glass rod (1); cooling-water temperature sensor (2); at least two level electrodes (3); interior core print (4) is outer respectively with electric silica gel and the interval compacting of insulation silica gel; tightly be stuck on the plastics column cap (6) at the inner core that will suppress with silica gel with frock in the manufacturing process, carry out seal protection.
As shown in Figure 2, at the interior core print (4) of underneath type water temperature-level sensor draw-in groove is arranged respectively up and down, little pcb board (5) and glass rod (1) combination are installed.This structure has been accomplished saving material, environmental protection, easy to make, simple in structure, good seal performance, high performance purpose.
Adopt the underlying sensor environmental protection of this design, easy for installation, good airproof performance, corrosion resistance is strong, can effectively prolong the serviceable life of sensor.
Claims (2)
1. underneath type water temperature-level sensor; its inner core comprises glass rod (1); cooling-water temperature sensor (2); at least two level electrodes (3); interior core print (4) and little pcb board (5); glass rod (1) and little pcb board (5) are combined by (4) simple and practical forms easy for installation of interior core print; be connected with cooling-water temperature sensor (2) at little pcb board (5); level electrode (3); realize the detection of water-temperature water-level; simultaneously at glass rod (1); cooling-water temperature sensor (2); at least two level electrodes (3); interior core print (4) is outer respectively with electric silica gel and the interval compacting of insulation silica gel; tightly be stuck on the plastics column cap (6) at the inner core that will suppress with silica gel with frock in the manufacturing process, carry out seal protection.
