ABSTRACT:
An acceleration detector comprising a substantially hollow cylindrical acceleration transducer assembly including a piezoelectric element, an inertial weight and an output terminal in a stacked relationship. The acceleration transducer assembly is mounted on a cylindrical threaded bushing of a housing and is secured by a stop nut thread-engaged on the bushing. The stop nut has a contact surface at which the stop nut contacts and supports the inertial weight of the transducer assembly for securing the transducer assembly to the bushing. The contact surface is small enough to enable to obtain a substantially constant output over an oscillation frequency range of the acceleration to be detected.
