Description

A kind of liquid level sensor liquid level demarcates pick-up unit and method
Technical field
The present invention relates to liquid level sensor liquid level and demarcate field, particularly relate to a kind of liquid level sensor liquid level and demarcate pick-up unit and method.
Background technology
need to carry out liquid level demarcation after liquid level sensor processes, it is mostly carry out detection resistance by moving the position of liquid level sensor that its liquid level is demarcated, then curve plotting figure obtains, detect the standard mainly moved around by liquid level sensor float manually as detecting in the prior art, it must be deep in the middle of fuel tank, the position that liquid level sensor float is floating in fuel tank is on the one hand not easy to determine, on the other hand when manual mobile liquid level sensor, poor stability in its moving process, easy deflection or imbalance, affect the measurement of liquid level sensor resistance value, thus cause testing result error amount very large, and its detection method trouble, efficiency is low, request for utilization can not be met .
Summary of the invention
The object of the invention is the deficiency in order to make up prior art, provide a kind of liquid level sensor liquid level and demarcate pick-up unit and method, liquid is released by fluid level tube, while the change of liquid level, the curtage of liquid level sensor to be detected also can change with the change of liquid level, the testing result error amount made reduces greatly, not only increase the accurate performance of liquid level sensor, simultaneously easy to detect, work efficiency is high.
The present invention is achieved through the following technical solutions:
A kind of liquid level sensor liquid level demarcates pick-up unit and method, include base, it is characterized in that: described base is added is provided with support, described support is provided with claw, base below described claw is provided with fluid level tube, the upper end of described fluid level tube is provided with inlet, lower end is provided with liquid outlet, the discharge nozzle that described liquid outlet is communicated with is provided with flow valve, the side of described fluid level tube is provided with a liquid level equilibrium pipe concordant with it, described liquid level equilibrium pipe is transparent liquid level equilibrium pipe, it is distributed with scale mark, the described bottom of liquid level equilibrium pipe is communicated with the bottom of fluid level tube.
Described liquid level equilibrium pipe is glass tube or lucite pipe.
Described claw is installed with liquid level sensor to be detected, and the float of liquid level sensor to be detected is positioned at fluid level tube, concrete steps are as follows: first in fluid level tube, load onto quantitative oil or water, make the float of clamping liquid level sensor to be detected at oil or water float, then the flow valve of fluid level tube is opened, thus the float of liquid level sensor to be detected is moved in oil or water, the data line of described liquid level sensor to be detected is connected with single-chip data processor, real-time calculating and curtage in display liquid level sensor to be detected with the change of float displacement movement, simultaneously in conjunction with the level value of liquid level equilibrium pipe, by the curtage of same time list liquid level sensor to be detected and the level value of liquid level equilibrium pipe, simulate the curve coefficients between the curtage of liquid level sensor to be detected and the level value of liquid level equilibrium pipe, curve coefficients remote mode or short range mode are input among the calculation procedure in single-chip data processor, namely the oil mass completing liquid level sensor to be detected is demarcated.
Its principle is: release liquid by fluid level tube, while the change of liquid level, the curtage of liquid level sensor to be detected also can change with the change of liquid level, liquid level sensor is contained on claw, the bottom of fluid level tube is provided with liquid outlet, its good stability, be not easy deflection, keep balance, facilitate electric current, the stably measured of voltage, and described liquid level equilibrium pipe is transparent liquid level equilibrium pipe, directly can observe the level value of liquid level equilibrium pipe indirect observation fluid level tube, the testing result error amount made reduces greatly, improve the accurate performance of liquid level sensor, do not need to carry out in mailbox when it detects simultaneously, easy to detect, work efficiency is high.
Advantage of the present invention is:
Reasonable in design of the present invention, liquid is released by fluid level tube, while the change of liquid level, the curtage of liquid level sensor to be detected also can change with the change of liquid level, the testing result error amount made reduces greatly, improve the accurate performance of liquid level sensor, easy to detect, work efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
