ABSTRACT:
Amplifier apparatus for providing output motion correlated to condition change motion or deflection of a condition responsive element. The amplifier in a preferred embodiment is mounted onto the condition responsive element for floating conjoint movement therewith. A remotely connected actuator, extending into the motion path, defines a pivot axis for a hinged gear sector arm of the amplifier. In pivoting about the actuator axis, the sector arm operably drives a rotatable output shaft supporting a pointer or the like.
