Process variable transmitter with display
First Claim
1. A process variable transmitter having a display for use in measuring a process variable of an industrial process, comprising:
- a housing having an internal wall which divides an internal cavity of the housing into a first portion which may be exposed to an environment and a sealed portion;
a process variable sensor configured to sense the process variable of the industrial process;
transmitter circuitry in the second portion of the housing coupled to the process variable sensor configured to provide a transmitter output;
a terminal block in the first portion of the housing configured to couple to the transmitter circuitry through the internal wall, the terminal block mounted on the internal wall;
a first rotatable connector on the connection member including a plurality of first conductors, the first rotatable connector mounted on the terminal block and located in the first portion; and
a display module having a display thereon and a second rotatable connector having a plurality of second conductors coupled to the display, the plurality of first conductors configured to electrically connect to the plurality of second conductors, wherein the display module is rotatable about the connection member at the first and second connectors and the display module is located in the first portion.

9. A method in a process variable transmitter of the type used in an industrial process for coupling a display to a terminal block comprising:
-
placing the terminal block in the first portion of the housing; providing an inner wall in the housing which defines a first portion which may be exposed to an environment and a second sealed portion; sensing a process variable using a process variable sensor; receiving the process variable from the process variable sensor using measurement circuitry in the second portion of the housing and responsibly providing a transmitter output; providing a first rotatable connector on the terminal block which includes a plurality of conductors; mounting the terminal block to the inner wall and located in the first portion; providing a display in the first portion having a display element carried thereon and a second rotatable connector having a plurality of second conductors; connecting the first rotatable connector to the second rotatable connector to thereby provide an electrical connection between the first and second electrical conductors; and placing an end cap on the housing. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
