Frequently Asked Questions (FAQs) about Fluorescent Fiber Optic Temperature Sensing
1. What is the principle of fluorescent fiber optic temperature sensing?
Fluorescent fiber optic temperature sensors use a special material (typically a phosphor) at the tip of the optical fiber. When excited by a light source, this material emits light (fluoresces). The decay time (the time it takes for the fluorescence to diminish) is directly related to the temperature. By measuring the decay time, the sensor accurately determines the temperature.
2. What are the advantages of fluorescent fiber optic temperature sensors over traditional sensors (thermocouples, RTDs)?
- Immunity to electromagnetic interference (EMI) and radio frequency interference (RFI).
- Intrinsic safety in high-voltage environments (no electrical conductivity).
- High accuracy and stability.
- Small size and flexibility.
- Long lifespan and minimal drift.
- Ability to measure in harsh environments (high temperatures, corrosive chemicals).
3. How is fluorescent fiber optic sensing different from distributed fiber optic sensing (like Raman or Brillouin scattering)?
Fluorescent sensors are *point* sensors, meaning they measure temperature at a specific location (the tip of the fiber). Distributed sensors (Raman, Brillouin) measure temperature *along the entire length* of the fiber. Distributed sensing is useful for long distances, but fluorescent sensing offers higher accuracy and faster response times at discrete points.
4. How is fluorescent fiber optic sensing different from Fiber Bragg Grating (FBG) sensors?
FBG sensors measure temperature based on shifts in the wavelength of light reflected by a grating written into the fiber. While FBGs can be multiplexed (multiple sensors on one fiber), they are generally less accurate than fluorescent sensors at high temperatures and can be more susceptible to strain-induced errors. Fluorescent sensors are generally more robust in harsh environments.
5. What is the typical accuracy of a fluorescent fiber optic temperature sensor?
Accuracy typically ranges from ±0.5°C to ±2°C, depending on the specific sensor and signal conditioner. FJINNO's systems often achieve ±0.5°C or better.
6. What is the temperature range of fluorescent fiber optic sensors?
The temperature range varies depending on the specific sensor materials, but can range from cryogenic temperatures (-200°C) to very high temperatures (up to 400°C or even higher with specialized materials).
7. What is the lifespan of a fluorescent fiber optic sensor?
Fiber optic sensors are very durable and have a long lifespan, often exceeding 20 years with proper installation and use.
8. Can fluorescent fiber optic sensors be used in explosive environments?
Yes, because they are intrinsically safe (no electrical components at the sensing point).
9. Can fluorescent fiber optic sensors be used in high-vibration environments?
Yes, they are generally very robust and resistant to vibration.
10. What is a signal conditioner (or temperature transmitter)?
The signal conditioner is the electronic unit that sends the excitation light to the sensor and processes the returning fluorescent signal to determine the temperature. It provides the output (analog or digital) to a monitoring system.
11. What types of outputs do signal conditioners provide?
Common outputs include analog signals (4-20mA, 0-10V), and digital signals (RS-485 Modbus, Ethernet/IP, etc.).
12. Can multiple fluorescent sensors be used with one signal conditioner?
Yes, multi-channel signal conditioners are available, allowing for simultaneous monitoring of multiple points.
13. What is a fiber optic feedthrough?
A fiber optic feedthrough is a device that allows the optical fiber to pass through a barrier (e.g., a transformer tank wall) while maintaining a seal.
14. What is the typical installation process for a fluorescent fiber optic sensor?
Installation typically involves routing the fiber optic cable, securing the sensor probe to the measurement point, and connecting the fiber to the signal conditioner. FJINNO provides detailed installation instructions and support.
15. Can FJINNO provide customized sensor solutions?
Yes, FJINNO specializes in custom solutions, including probe design, cable length, connector type, and signal conditioner configuration.
16. Does FJINNO offer OEM/ODM services?
Yes, FJINNO works with equipment manufacturers to integrate fiber optic temperature sensing into their products.
17. What is the advantage of using FJINNO's sensors in dry-type transformers?
FJINNO's sensors are small, flexible, and EMI-immune, making them ideal for the confined spaces and high electromagnetic fields within dry-type transformers.
18. What is the advantage of using FJINNO's sensors in oil-immersed transformers?
FJINNO's sensors are highly accurate and stable, providing reliable long-term monitoring of winding hot spots, which is crucial for preventing transformer failures.
19. What is the advantage of using FJINNO's sensors in switchgear?
FJINNO's sensors provide early warning of overheating in critical switchgear components, preventing costly downtime and ensuring safe operation.
