Description
Technical field
The present invention relates to the liquid level sensor liquid level and demarcate field, relate in particular to a kind of liquid level sensor liquid level and demarcate pick-up unit and method.
Background technology
after processing, liquid level sensor needs to carry out the liquid level demarcation, it is mostly to move and detected resistance by the position to liquid level sensor that its liquid level is demarcated, then curve plotting figure obtains, detect in the prior art is mainly the standard manually the liquid level sensor float moved around as detecting, it must be deep in the middle of fuel tank, liquid level sensor float floating position in fuel tank is not easy to determine on the one hand, on the other hand when hand-driven moving hydrodynamic level sensor, poor stability in its moving process, easy deflection or imbalance, affect the measurement of liquid level sensor resistance value, thereby cause the testing result error amount very large, and its detection method trouble, efficiency is low, can not meet request for utilization
.
Summary of the invention
The objective of the invention is in order to make up the deficiency of prior art, provide a kind of liquid level sensor liquid level to demarcate pick-up unit and method, emit liquid by fluid level tube, in the time of the variation of liquid level, the curtage of liquid level sensor to be detected also can change with the variation of liquid level, the testing result error amount made reduces greatly, not only improved the accurate performance of liquid level sensor, simultaneously easy to detect, high efficiency.
The present invention is achieved through the following technical solutions:
A kind of liquid level sensor liquid level is demarcated pick-up unit and method, include base, it is characterized in that: the added support that is provided with of described base, described support is provided with claw, the base of described claw below 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, one 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, be distributed with scale mark on it, the bottom of described 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: at 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 open the flow valve of fluid level tube, thereby 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 the single-chip data processor, calculate in real time with show curtage in liquid level sensor to be detected with the float displacement variation of moving, while is 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 level value of the curtage of liquid level sensor to be detected and liquid level equilibrium pipe, curve coefficients is input among the calculation procedure in the single-chip data processor by remote mode or short range mode, the oil mass that completes liquid level sensor to be detected is demarcated.
Its principle is: by fluid level tube, emit liquid, in the time of the variation of liquid level, the curtage of liquid level sensor to be detected also can change with the variation 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, can directly observe the level value of liquid level equilibrium pipe indirect observation fluid level tube, the testing result error amount made reduces greatly, improved the accurate performance of liquid level sensor, when it detects simultaneously, need in mailbox, not carry out, easy to detect, high efficiency.
