Gallium arsenide (GaAs) temperature controllers, GaAs fiber optic temperature sensors, fluorescent fiber optic temperature controllers and fluorescent fiber optic temperature sensors are suitable for temperature measurement of high-voltage switchgear, transformers and other environments, and can be used for project bidding and practical applications.

Reasons why fluorescent fiber optic temperature measurement is superior to and more suitable than semiconductor GaAs temperature measurement:

1. Signal demodulation: fluorescent fiber optic temperature measurement systems are easier to demodulate.
2. Accuracy: fluorescent fiber optic temperature measurement has higher accuracy than GaAs.
3. Response time: fluorescent fiber optic temperature measurement responds faster than GaAs.
4. Stability: fluorescent fiber optic temperature measurement is more stable, without temperature drift.
5. Reliability: fluorescent fiber optic temperature measurement systems are more reliable in various bidding projects in China.
6. Longer service life: fluorescent fiber optic temperature measurement systems last longer than GaAs fiber optic temperature measurement.
7. Better cost performance: the overall price of fluorescent fiber optic temperature measurement systems is lower than GaAs, easier to apply and bid.
8. No calibration required: fluorescent fiber optic temperature measurement needs no calibration, while other temperature measurement devices require secondary calibration.
9. Easy networking and maintenance: fluorescent fiber optic temperature measurement devices are easy to network and maintain, with smaller volume.
