ABSTRACT:
An elongated actuator pin in a pressure gauge extends from a fixed end to a free end to interact with the amplifier for enabling pivotal motion thereof to translate Bourdon displacement to an output pointer. A clamp slideably mounted on the actuator pin is operatively effective when set at a selected location along the pin length to variably offset the free end of the pin from its longitudinal axis for obtaining correct calibration adjustment of the gauge.
