摘要： A lever beam is mounted for pivotal movement, with electromagnetic forces applied to one end, and pneumatic forces applied to the other. A nozzle applies pressurized air against a planar surface of a baffle plate and provides a pneumatic signal that is a function of the distance between the nozzle opening and the planar surface. An alignment mechanism adjusts the planar surface parallel to the nozzle opening to provide a close fit cut-off. A span adjustment controls the position of the nozzle. A damper is coupled to the lever beam at the fulcrum and assumes the pivot point of the lever mechanism. An zero mechanism is provided for balancing the lever under a zero signal input condition.

摘要： A movable carriage is mounted via threaded connection to a rotatable adjusting element. A guide limits the rotational movement of the carriage. Resilient forces are applied to the carriage in a first direction to assure a tight coupling between the threaded connection, and in a second direction to assure a tight coupling between the guide and the carriage, thereby reducing the backlash and/or deadband in the mechanism to an acceptable level.
