容器１の中心軸上に位置するようになつている。 FIGS. 1a and 1b are diagrams showing a sensor section of an inclinometer according to an embodiment of the present invention. As shown in both figures, an electrolytic solution 2 is filled in a cylindrical container 1 made of a conductive material and attached to an object to be measured. The support member 3 has its lower end fixed to the upper end of the cylindrical container 1, and is moved via a conductive wire 4 from a support point 3a located at the intersection of the central axes of the support member 3 and the cylindrical container 1.

常に正確に傾斜角の検出ができる。 In this embodiment, when the object to be measured to which the inclinometer is attached is horizontal, the cylindrical container 1 is also horizontal, and the movable electrode 5 suspended by the wire 4 is placed on the central axis of the cylindrical container 1. Therefore, the resistance value of the detection resistor R4 between the cylindrical container 1 and the moving electrode 5 at this time is taken as the reference value. Therefore, when the object to be measured is tilted, the cylindrical container 1 is tilted, but the movable electrode 5 suspended by the wire 4 is always located in the vertical direction. Approach side 1. Therefore, the detection resistance R
The resistance value of No. 4 changes by a value corresponding to the inclination angle.
As a result, even if the input voltage v i of the detection section is constant, the output voltage v 0 changes in accordance with the tilt angle. That is, the inclination angle of the object to be measured is detected from the value of the output voltage v 0 regardless of the direction of inclination. Furthermore, when the electrical resistance of the electrolytic solution 2 itself in the sensor section changes due to temperature changes, the electrical resistance of the correction electrolytic solution 6 in the correction container 7 changes as well, so temperature correction is performed and the tilt angle is always accurately detected. I can do it.

よい。 In addition, when the cylindrical container containing the electrolytic solution is formed of an insulating material, as shown in FIG. The detection section may be configured such that the electric resistance between the movable electrode 5 and the fixed electrode 10 operates in the same manner as the detection resistor R4 in FIG. In short, when viewed from the movable electrode 5 when the cylindrical container 9 is horizontal, the electric resistance of the fixed electrode is the same in any direction.
The fixed electrode 10 may be placed inside the cylindrical container 9.

Since the angle of inclination is detected from the change in electrical resistance between the two, it is possible to measure the inclination in any direction, regardless of the direction of the inclination of the object to be measured. Furthermore, the tilt angle can be accurately detected even if the temperature of the measurement environment changes.
