Using beryllium bronze material with good elastic property as vibration element

design a tilt sensor with ‘sandwich’ type differential capacitance detection structure

the sensing head structure size

the mechanics characteristic of the sensor is analyzed using mechanics of elasticity relationship between measured angle and beryllium copper coin angle is deduced. By using single chip microcomputer

the output linearity of tilt sensor is increased using the method of software linearity compensation. The sensor has simple structure

low cost

good stability

and it is easy to use

and after being test within the whole range

the maximum error is up to 6 °.
