Claims
- 1. A method for acquiring and transmitting data between two or more positions or locations relative to a detected condition and/or event in a plant, said method comprising the steps:
positioning or locating at least one detector in said plant to detect a condition or event at a plant position or location; positioning at least one battery-powered radio frequency transmitter in said plant in communication with said at least one detector , said transmitter having a transmittable identification code and capable of transmitting a signal relative to said identification code, the detector, and the battery; providing a central processing location for receiving a signal from said battery-powered transmitter relative to the identification code, a condition or event detected at a position or location in said plant, and the battery; and providing at least one other transmitter in communication with said central processing location, said other transmitter capable of transmitting signals relative to a condition or event detected at a position or location in said plant.
- 2. The method of claim 1, further comprising the step of positioning or locating at least one more detector and/or sensor to detect and/or sense a condition or event at a plant position or location.
- 3. The method of claim 2, further comprising positioning at least one transmitter in communication with said at least one more detector and/or sensor.
- 4. The method of claim 3, wherein the one battery-powered radio frequency transmitter is a spread spectrum transmitter.
- 5. The method of claim 4, wherein the one battery-powered radio frequency transmitter is a 900 megahertz spread spectrum transmitter.
- 6. The method of claim 1, wherein the one battery-powered radio frequency transmitter is a 900 megahertz spread spectrum transmitter and transmits on predetermined time intervals.
- 7. The method of claim 1, wherein said at least one other transmitter comprises a radio frequency transmitter.
- 8. The method of claim 7, wherein said at least one other transmitter comprises a spread spectrum radio frequency transmitter.
- 9. The method of claim 8, wherein said at least one other transmitter comprises a 900 megahertz spread spectrum radio frequency transmitter.
- 10. The method of claim 4, wherein said at least one other transmitter comprises a 900 megahertz spread spectrum radio frequency transmitter.
- 11. The method of claim 1, wherein the plant is a pharmaceutical plant.
- 12. The method of claim 1, wherein the plant is a refinery.
- 13. The method of claim 1, wherein the plant is a petrochemical plant.
- 14. The method of claim 1, wherein the plant is a food processing plant.
- 15. The method of claim 4, wherein the plant is a pharmaceutical plant.
- 16. The method of claim 4, wherein the plant is a refinery.
- 17. The method of claim 4, wherein the plant is a petrochemical plant.
- 18. The method of claim 4, wherein the plant is a food processing plant.
- 19. The method of claim 1, wherein the at least one detector sensor is positioned in communication with a pipe in said plant.
- 20. The method of claim 1, wherein the at least one detector is positioned in communication with a valve in said plant.
- 21. The method of claim 1, wherein the at least one detector is positioned in communication with an enclosure in said plant.
- 22. The method of claim 15, wherein the at least one detector detects a temperature.
- 23. The method of claim 16, wherein the at least one detector detects a pressure.
- 24. The method of claim 1, wherein the at least one detector detects a level.
- 25. The method of claim 21, wherein the at least on detector detects a level.
- 26. The method of claim 23, further comprising at least a second detector in said plant, said second detector in communication with at least one battery-powered radio frequency spread spectrum transmitter, said second detector detecting temperature.
- 27. The method of claim 21, wherein the at least one detector detects emissions.
- 28. The method of claim 21, wherein the at least one detector is an adsorption detector.
- 29. The method of claim 1, wherein the at least one detector detects emissions.
- 30. The method of claim 1, wherein the at least one detector is positioned in communication with a pipe enclosure.
- 31. The method of claim 1, wherein the at least one detector is positioned in communication with a valve stuffing box enclosure.
