ABSTRACT:
A differential pressure transmitter, a pneumatically operated square root extracting device therefor and methods of making the same are provided, the transmitter having a rod operatively interconnecting a movable wall with a cam roller to cause the roller to roll on a flat surface as the value of the pressure in an output chamber defined by the movable wall changes, the rod and the movable wall respectively having universal joint units snap-fitted together to provide for universal movement therebetween while movement of the wall causes the roller to roll.
