The underneath type sensor
Technical field
The utility model relates to a kind of underneath type sensor, belongs to the technical field of solar water heater perception water-level and water-temperature device.
Background technology
What adopt mostly with the supporting sensor of solar water heater in the market is conduction hammer sensor, maglev type sensor and capacitance type sensor, sensor element non-refractory, failure rate height, install at side, install water nozzle in addition additional, make complexity and not attractive in appearance is installed.
Summary of the invention
The purpose of this utility model is that a kind of underneath type sensor will be provided, its compact conformation and easy to make, good looking appearance also has only resistant to elevated temperatures part to immerse in the water, and circuit board 17 parts are away from the water tank 19 of water source and high temperature, so failure rate is low and long service life.
The structure of underneath type sensor is the level electrode 5 of packing on every side of 9 bottoms, the sensor seat of honour, the upper end of this level electrode 5 is fixed on the platform at the sensor seat of honour 9 with nut 7 and O type terminal 6, the middle part plug-in mounting temperature sensing tube 8 of 9 bottoms, the sensor seat of honour, temperature-sensitive piece 11 is housed in its inner chamber, and temperature sensing tube 8 upper ends are tightened solid by the screw thread and the seat of honour 9 and are filled in perforated rubber stopper 10 and seal with fluid sealant; The lower end of temperature sensing tube 8 puts O type silicon rubber loop 12 earlier and is inserted in the hole at middle part of following 2 of sensor again; Pad 4 and nut 3 are fixing, and the flange 20 on the temperature sensing tube 8 is the O type silicon rubber loop 12 of clamping sleeve on temperature sensing tube 8 just in time, and following 2 of sensor shell 15 and sensor are tightened mutually.
The advantage of underneath type sensor is that power pack is away from water tank, so circuit working is stable, level electrode, temperature sensing tube adopt corrosion resistant stainless steel material to make, so sensor has the characteristics of corrosion-resistant high temperature resistance, sensor places the bottom in the water tank, simple installation.
