Abstract
The invention relates to an electronic leveling instrument which is characterized in that a measuring circuit thereof comprises a current meter, a resistor, a power supply and a sensor, wherein the resistor and a zero potentiometer are symmetrically connected in series between an anode and a cathode of the current meter; the movable end of the potentiometer is connected in series with a power supply switch and the power supply; the anode and the cathode of the current meter and a cathode of the power supply are respectively measuring electrodes; the end parts of the three electrodes are distributed on the same horizontal line at equal intervals; a sensor body is in a container shape; the electrodes are inserted into the same plane of electrolyte in the sensor body; all components are installed in a shell and on a panel; and the measuring electrodes are led out. The resistor, the potentiometer and resistors among the measuring electrodes form a measuring electrical bridge circuit in the measuring circuit. When the surface of a measured object is inclined, a pointer of the current meter deflects, and an inclining angle and the inclining direction of the surface can be judged according to the deflecting angle and direction of the pointer. The electronic leveling instrument is suitable for different environments and has high sensitivity.
Description
Technical field
The present invention relates to a kind of measurement mechanism, particularly a kind of electronic leveling instrument.
Background technology
In commercial production and rigging up and debugging process, often will carry out horizontal survey to the surface of product or equipment, traditional horizontal measuring instrument is a bubble type structure, under the poor environment such as, dim light narrow and small for the space, then be difficult to accurately measure, even can't measure.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned weak point, and a kind of widely applicable, highly sensitive electronic leveling instrument is provided.
The object of the present invention is achieved like this: electronic leveling instrument comprises shell, it is characterized in that its metering circuit is made up of galvanometer, resistance, power supply, sensor.
During use, sensor is placed on the testee surface, when the testee surface tilt, the galvanometer needle deflection according to the angle and direction of needle deflection, can be judged the angular dimension and the vergence direction of surface tilt, is fit to use under the varying environment, and is highly sensitive.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is a metering circuit circuit diagram of the present invention.
Embodiment
Now illustrated embodiment is made detailed description to the present invention in conjunction with the accompanying drawings.
As shown in Figure 2, series resistor R successively between the galvanometer G positive and negative electrode in the metering circuit

P, resistance R
2, R
PMovable end serial connection power switch K, power supply V
D, G positive and negative electrode, V
DNegative pole is respectively potential electrode A, C, B, and three electrode tips are on the same horizontal line and equidistantly distribute, and electrode B is positioned at the centre of A, C, and sensor body is a container shapes, and electrode A, B, C insert the place, same plane of sensor body electrolyte inside.Each element is installed in the enclosure, on the panel, draw potential electrode.
In the metering circuit of this measuring instrument by R
P, R
1, R
2And the resistance between potential electrode constitutes the measuring bridge circuit.Before the measurement, earlier at the plane of standard adjusted R
PMake galvanometer G nulling, measure again, when the testee surface tilt, surface of contact change between electrolytic solution in the sensor body and three electrodes causes that the resistance of interpolar produces corresponding variation, electric bridge out of trim, galvanometer G needle deflection, the angle of inclination is big more, and the pointer beat is also big more, simultaneously, also can be according to the deflection to the left or to the right of galvanometer G pointer, the vergence direction of judging tested surface is left or to the right, therefore, this measuring instrument also can be used for measurement of angle to be used.
