（発明の背景）
先に本発明者等は、実開昭５６−１０７５１０号に示す
ような傾き検出センサを開発した。(Background of the Invention) The present inventors previously developed a tilt detection sensor as shown in Japanese Utility Model Application No. 107510/1983.

を検出するようにしている。As shown in Fig. 1, this senna is constructed by putting a liquid 3 into a U-shaped tube 2 connected by an air tube 1, and enclosing a float 4 having a pair of magnets at the liquid level at one end. A Hall element 5 is disposed between the floats 4, and as the float moves up and down, each 1&stone approaches and moves away from the Hall element 5 to change the output of the Hall element, thereby detecting the inclination of the 0-shaped tube. That's what I do.

の実用化面での問題点が指摘されていた。However, in the case of such a sensor, for example, in the case of a rotary work machine of a tractor, vibration stability is poor, and the output voltage of the Hall IC is proportional to the magnetic field. It has been pointed out that there are problems in practical use, such as non-linearity with respect to distance and the need for correction of the detection signal.
