Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of the utility model drum type brake magnetoelectricity liquid level sensor.
Embodiment
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the cross-sectional schematic of the utility model drum type brake magnetoelectricity liquid level sensor, with reference to Fig. 1, the utility model, drum type brake magnetoelectricity liquid level sensor, comprises cylindrical shell 2, copper pipe 6, circuit board assemblies 3, ball float 8, magnet 9, and above-mentioned cylindrical shell 2 is airtight, above-mentioned copper pipe 6 is contained in above-mentioned cylindrical shell 2, foregoing circuit board component 3 is shaft-like and is arranged in above-mentioned copper pipe 6, and above-mentioned ball float 8 is sleeved on above-mentioned copper pipe 6 and also can slides along above-mentioned copper pipe 6, and above-mentioned magnet 9 is arranged in above-mentioned ball float 8.
Above-mentioned cylindrical shell 2 top is provided with wire assembly 1.
Be provided with bottom 10 bottom above-mentioned cylindrical shell 2, sealed by above-mentioned bottom 10 bottom above-mentioned cylindrical shell 2.
Above-mentioned cylindrical shell 2 top peripheral is provided with a circle outside seal 4.
Above-mentioned copper pipe 6 stretches out above-mentioned cylindrical shell 2 top, and copper pipe 6 suit stretching out above-mentioned cylindrical shell 2 is provided with inner seal liner 5.
Be provided with filling material 7 in above-mentioned copper pipe 6, epoxy encapsulating selected by filling material 7.
During its work: ball float 8 moves up and down along copper pipe 6 by liquid level height buoyancy, magnet 9 is established due to interior, therefore when the magnetic ball float 8 of tool fluctuates with liquid level, make to be arranged on magnetic switch on circuit board assemblies 3 (tongue tube, how you element or magnetodiode) conducting and disconnection, thus the change of liquid level is converted to output resistance change.
When liquid level is the highest, ball float 8 is also the highlyest floating, at this moment the resistance exported minimum (or maximum), decline ball float with liquid level also declines, resistance becomes with the decline of ball float 8 large (or diminishing), converts resistance (input moving-coil instrument or electronic digital meters) continuously and constantly and indicates liquid level height.
The main operational principle of circuit board assemblies 3:
According to the difference of various container, design magnetic switch and resistance on circuit boards.Resistance is all connected on a magnetic switch in parallel below of each resistance, and last resistance is directly communicated with, and does not install switch.Magnet on ball float can keep the conducting simultaneously of two switches, when liquid level declines, when magnet is about to leave and disconnects a upper magnetic switch, magnet has made next switch conduction, but the resistance value exported still be the resistance of the preceding paragraph, when liquid level declines a upper switch disconnection again, the conducting before the switch-off of next switch, at this moment the resistance exported is the resistance of next section, and the rest may be inferred, makes sensor export continual resistance.And adding a warning output in the sensor when liquid level drops to minimum point, ball float also drops to bottom thereupon, is at this moment used as to report to the police.Magnetic switch conducting output current, informs user by the attention device be attached thereto.
The utility model, drum type brake magnetoelectricity liquid level sensor, compare the conventional art of mechanical slip formula, have easy for installation, measuring accuracy is high, stable performance, corrosion-resistant, safe and reliable, long service life, shock resistance are strong, on-deformable feature in packaging and storing, overall construction design is comparatively exquisite, and result of use is better.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to allow the personage being familiar with this art can understand the utility model content and be implemented, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
