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.
Claims8
A motion amplifier for a gauge instrument having a motion producing condition responsive element, said amplifier comprising in combination:
- a. a support frame;
- b. pivot means pivotally supported on said support frame and including receiver means in which to receive an actuator operably connected to the condition responsive element for pivoting said pivot means in correlation to the motion produced by said element;
- c. mounting means adapted for mounting said support frame and said pivot means as a unit on a stationary portion of the gauge instrument;
- and
- d. calibration means adjustable to displace said unit on said mounting means relative to the received actuator for effecting presettable operational accuracy of the amplifier.
A condition responsive gauge instrument comprising in combination:
- a. a condition responsive element producing motion in response to condition changes to which it is sensitive;
- b. actuator means operably connected to said condition responsive element for floating conjoint movement therewith;
- c. a motion amplifier including:
- 1. a support frame;
- and
- 2. pivot means pivotally supported on said support frame and including receiver means in which to receive said actuator for pivotting said pivot means in correlation to the motion produced by said element;
- d. mounting means adapted for mounting said support frame and said pivot means as a unit on a stationary portion of the gauge instrument;
- and
- e. calibration means adjustable to displace said unit on said mounting means relative to the received actuator for effecting presettable calibration accuracy of the amplifier.
