Abstract
An electromagnetic liquid viscosity coefficient testing instrument is characterized by comprising a measuring cylinder. Two electromagnetic sensors are arranged on the measuring cylinder and connected with a main control circuit board through a lead, the main control circuit board is installed in a casing, a panel is arranged on the casing, a display screen is installed on the panel and connected with the main control circuit board through a lead, and an operation key is arranged on the panel. The electromagnetic liquid viscosity coefficient testing instrument has the advantages that in an experiment of testing liquid viscosity coefficient through a falling-ball method, the electromagnetic sensors are used for testing a falling position of steel balls, human factors can be removed, and a testing result is high in precision. Steel ball falling speed is calculated through a single-chip microcomputer on the main control circuit board, speed value is displayed directly through the display screen, a steel ball falling speed calculating process is avoided, and operation is convenient and fast.
Description
Technical field
The utility model relates to a kind of Mechatronic device, in particular for doing the electromagnetic liquid tester for viscosity factor of Physical Experiment.
Background technology
In the Physical Experiment of middle school or university, the experiment of the coefficient of viscosity of measuring liquid is arranged.Usually adopt falling ball method in the experiment.Method is the fluid to be measured of packing in graduated cylinder, put into the steel ball of specified diameter to liquid surface, when treating that steel ball at the uniform velocity falls, measure certain segment distance institute's time spent that steel ball descends with stopwatch and ruler, then calculate the speed that steel ball descends, calculate the coefficient of viscosity of fluid to be measured by formula.This method need to be observed the position that steel ball descends by people's eyes, then manually presses manual time-keeping, and human factor is more, and measuring error is larger.
Summary of the invention
For addressing the above problem.The utility model provides a kind of electromagnetic liquid tester for viscosity factor, this electromagnetic liquid tester for viscosity factor detects the position that steel ball descends automatically by sensor, automatically calculate the speed that steel ball descends by main control circuit, show by display.Do not have human factor, measured result is more accurate,
The technical scheme that the utility model technical solution problem adopts is: invent a kind of electromagnetic liquid tester for viscosity factor, be characterized in: the electromagnetic liquid tester for viscosity factor has a graduated cylinder, at graduated cylinder two electromagnetic sensors are installed, electromagnetic sensor connects a main control board by wire, main control board is installed in the housing, and housing is provided with panel, and display screen is installed on the panel, display screen connects main control board by wire, fitting operation button on the panel.
The beneficial effects of the utility model are that in the experiment of the coefficient of viscosity that adopts falling ball method measurement liquid, the utility model adopts electromagnetic sensor to measure the position, whereabouts of steel ball, can eliminate human factor, measurement result degree of accuracy height.Calculate the steel ball decline rate by the single-chip microcomputer on the main control board, and by the direct display speed value of display screen, remove the process of calculating the steel ball decline rate from, convenient to operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the front view of present embodiment, and accompanying drawing 2 is vertical views of present embodiment.
