Abstract

A transmitter for use in a process control system for monitoring an industrial process includes a housing having a top and a bottom and a height extending therebetween. A parallelogram display is mounted to the housing. Sides of the parallelogram display are arranged at angles relative to the height of the housing.

Claims

1. A transmitter for use in a process control system for monitoring an industrial process, comprising:

a housing having a top and a bottom and a height extending therebetween;

a process variable sensor configured to sense a process variable of the process and responsively provide a process variable output;

transmitter circuitry in the housing configured to provide a display output;

a parallelogram display mounted to the housing with sides of the parallelogram display at an angle relative to the height of more than zero degrees and less than ninety degrees; and

the display configured to display information in response to the display output.

2. The apparatus of claim 1 wherein the parallelogram comprises a rectangle.

3. The apparatus of claim 1 wherein the parallelogram display comprises a square.

4. The apparatus of claim 1 wherein an angle between a side of the parallelogram display and the height is forty five degrees.

5. The apparatus of claim 1 wherein the parallelogram display includes at least one display segment having a length and display segment length is generally parallel with the height.

6. The apparatus of claim 5 including a second display segment arranged at an angle to the height.

7. The apparatus of claim 1 wherein the parallelogram display includes at least one display segment having a length and the display segment length is generally perpendicular to the height.

8. The apparatus of claim 7 including a second display segment arranged at an angle to the height.

9. The apparatus of claim 1 including a mount configured to couple to the process and the height is in a direction away from the mount.

10. The apparatus of claim 1 wherein the sensor is located remotely from the transmitter housing and coupled to the transmitter circuitry through an electrical connection.

11. The apparatus of claim 1 wherein the sensor is contained in the transmitter housing.

12. The apparatus of claim 1 wherein the display is positioned remotely from the transmitter circuitry.

13. A transmitter for use in a process control system used to monitor an industrial process, comprising:

a housing;

a process variable sensor configured to sense a process variable of the process and provide a process variable output responsively;

transmitter circuitry coexisting in the housing configured to provide a display output; and

a parallelogram display configured to display information related to the display output and having four sides and mounted to the housing configured to display a plurality of characters aligned with a character axis, the character axis arranged at an angle of more than zero degrees and less than ninety degrees to the sides of the parallelogram display.

14. The apparatus of claim 13 wherein at least a portion of the characters are aligned with the sides of the display.

15. The apparatus of claim 14 wherein an angle between the character axis and a side of the parallelogram display is about 45°

.

16. The apparatus of claim 14 wherein the parallelogram comprises a rectangle.

17. The apparatus of claim 14 wherein the parallelogram display comprises a square.

18. The apparatus of claim 13 wherein the housing has a top and a bottom and a height extending therebetween and sides of the parallelogram are at an angle relative to the height of more than zero degrees and less than ninety degrees.

19. The apparatus of claim 18 wherein an angle between a side of the parallelogram display and the height is forty five degrees.

20. The apparatus of claim 18 wherein the parallelogram display includes at least one display segment having a length which is generally parallel with the height.

21. The apparatus of claim 18 wherein the parallelogram display includes at least one display segment having a length which is generally perpendicular to the height.

22. The apparatus of claim 18 including a mount configured to couple to the process and the height is in a direction away from the mount.

23. The apparatus of claim 13 wherein the sensor is located remotely from the transmitter housing and coupled to the transmitter circuitry through an electrical connection.

24. The apparatus of claim 13 wherein the sensor is contained in the transmitter housing.
