ABSTRACT:
A modular transmitter has an outer housing with a wall forming an interior cavity in which a control module is inserted. The wall has one or more ports therein that are connected to pressure conduits. When the control module is fully seated, the ports align with internal passageways in the control module that lead to control components in the control module. The control module further has an electrical circuit supported on an end thereof that is toward the inner end of the cavity when the control module is inserted and the circuit has components that removably mate with further elements mounted on the end wall of the cavity. These connections may include electrical contacts, and also rotationally adjustable components that have set points and which are coupled to set point adjustment and control shafts that are accessible from the opposite side of the end wall from the cavity. The coupling to the rotatable shafts permits not only rotationally driving the circuit components, but also accommodates some offset or misalignment between the two parts. Preferably, the coupling is a hook and loop type fastener that has two portions which can be separated in an axial direction, and will easily recouple for driving.
