1. An instrument for measuring acceleration, comprising:

  • a circular, metallic deflection part having a hole defined through its center;

    two electrode plates having a hole defined through their centers;

    a common casing having two parts, said deflection part held in a spring-elastic, membrane-like spaced manner between said two electrode plates and said deflection part and said two electrode plates in turn being placed between said two parts of said common casing, said deflection part and said electrode plates forming two adjacent capacitors;

    an electrical connecting wire; and

    electronic means for measuring acceleration in response to changes in capacitance of said capacitors;

    wherein said capacitors are electrically connected to said electronic means, and said electrical connecting wire is passed in a contact-free manner through said central hole in said deflection part and through holes in both electrode plates, said wire connecting the electrode plate more remote from the electronic means to the electronic means.
