Abstract

A potentiometer for attachment to objects undergoing strong vibrations, such as the engine block of an internal combustion engine has an outer housing which is secured to the object and an inner housing which is largely positioned inside the outer housing. The two housings are connected by at least one springy damping member, such as an O-ring made of rubber and, at the same time, they are largely uncoupled with respect to vibrations.
