Summary of the invention
Response has delay at existing obliquity sensor, has the defective of big time lag during work, the utility model provide a kind of can not lag behind current angle of inclination is converted into the obliquity sensor of electric signal.
For reaching above purpose, the utility model is to adopt following technical scheme to realize:
A kind of can not lag behind current angle of inclination is converted into the obliquity sensor of electric signal, comprise a tilt induction mechanism and a subtraction circuit, wherein, tilt induction mechanism comprises that an inside is equipped with the hollow tube of solid or liquid filler material and places two pressure transducers of two terminations of hollow tube respectively, the output terminal of hollow tube pressure at two ends sensor links to each other with two input ends of subtraction circuit respectively, the output signal of subtraction circuit is the output signal of this obliquity sensor, at any time, under any angle of inclination, that pressure transducer bore was only relevant with the angle of inclination of the weight of filler and hollow tube from the difference of the pressure of filler for two of hollow tube two ends, therefore, at any time, under any angle of inclination, the output signal of above-mentioned subtraction circuit is also only relevant with the angle of inclination of the weight of the filling material of adorning and hollow tube in the hollow tube, thereby, under the known situation of filling material weight, the output of this obliquity sensor has directly reflected the inclination angle of inclination of hollow tube.
In the such scheme, when hollow tube was placed with arbitrary angle, filler still closely contacted with the pressure transducer at hollow tube two ends.
The utlity model has following advantage:
1. not free hysteresis the when measuring the inclination angle realized the real-time monitoring to the angle of inclination fully.
2. simple and reliable for structure.
3. output signal is an electric signal, makes things convenient for computing machine that it is handled.
4. cost is lower.
