A process measurement display is disclosed that includes an indicator configured to change position to indicate a process variable. The display also includes an illumination source configured to provide light to the indicator. The display further includes a processor configured to control the illumination source to provide at least one additional output modality.
1. A process measurement display comprising:
an indicator configured to change position to indicate a process variable;
an illumination source configured to provide light to the indicator;
a first portion configured to receive light from the illumination source and a second portion configured to received light from the illumination source wherein the first portion has a different luminosity than the second portion; and
a processor configured to control the illumination source to provide at least one additional output modality.
2. The display of claim 1 , wherein the indicator is a needle.
3. The display of claim 2 , wherein the needle includes a light pipe coupled to the illumination source.
4. The display of claim 1 , wherein the illumination source is configured to provide different illumination colors to the indicator.
5. The display of claim 1 , wherein the additional output modality comprises a device status.
6. The display of claim 1 , wherein the additional output modality comprises a process variable status.
7. The display of claim 1 , wherein the additional output modality comprises a process alert.
8. The display of claim 1 , further comprising a gauge face, the indicator being configured to change position relative to the gauge face.
9. The display of claim 8 , wherein the gauge face includes measurement indicia thereon.
10. The display of claim 8 , wherein the gauge face includes a light pipe coupled to the illumination source.
11. The display of claim 8 , wherein the gauge face comprises a reflective material.
12. A process measurement display, comprising:
a measurement mechanism configured to receive a sensor signal and provide an indication of a process measurement;
a process variable output configured to generate a signal to display the indication of the process variable measurement;
an indicator configured to display the process variable measurement; wherein the the indicator has a first portion configured to display light and a second portion configured to display light wherein the first portion has a different luminosity than the second portion;
a status component configured to determine a process status, based on the indication of the process measurement; and
a status indicator that provides an indication of the determined process status to the display.
13. The process measurement display of claim 12 , wherein the status component is further configured to identify a process parameter and evaluate the indication of the process measurement with the process parameter.
14. The process measurement display of claim 13 , wherein the process parameter comprises a range of acceptable process measurements.
15. The process measurement display of claim 13 , wherein the status indicator is configured to provide an illumination from a light source, the illumination being indicative of the process status.
16. The process measurement display of claim 15 , wherein the illumination has a color that is indicative of the process status.
17. The process measurement display of claim 15 , further comprising:
a light transmitting element that directs the illumination from the light source to the status indicator; and
wherein the light source comprises an ambient light source.
18. The process measurement display of claim 17 , wherein the status indicator is disposed on a portion of a measurement identifier, the measurement identifier being configured to identify the indication of the process measurement.
19. The process measurement display of claim 17 , wherein the light transmitting element comprises a light pipe.
20. The process measurement display of claim 12 , wherein the measurement mechanism comprises a process variable sensor.
21. The display of claim 8 . wherein the gauge face comprises a first portion configured to receive light from the illumination source and a second portion configured to receive light from the illumination source, wherein the first portion has a different luminosity than the second portion.
22. A process measurement display comprising:
an indicator configured to change position to indicate a process variable;
an illumination source configured to provide light to the indicator;
a gauge comprising a first portion configured to receive light from the illumination source and a second portion configured to receive light from the illumination source, wherein the first portion has a different luminosity than the second portion; and
a processor configured to control the illumination source to provide at least one additional output modality.
