The T03 turbine speed probe is a non-contact speed measurement sensor designed based on the magnetoresistive effect or Hall effect principle. It is mainly used for speed monitoring of large rotating machinery such as steam turbines and generators. Its core function is to convert mechanical rotary motion into quantifiable electrical signals, providing real-time speed data for the unit control system and ensuring stable operation of equipment within safe thresholds. Featuring non-contact measurement, strong anti-interference performance and wide environmental adaptability, this probe is widely applied in critical scenarios including nuclear power generating units, thermal power units and industrial turbines.
Key Points for Installation and Maintenance of T03 Turbine Speed Probe
- Installation and Calibration For magnetoresistive probes, the air gap must be strictly controlled (e.g., 0.8mm ±0.2mm). Excessive deviation will cause signal attenuation or distortion. The probe shall be firmly tightened to prevent gap variation caused by loosening under vibration conditions. The signal cable shall be routed away from high-voltage circuits and protected with metal conduit shielding to reduce interference.
- Routine Maintenance Regularly clean oil contamination and iron filings on the probe surface, and inspect the grounding of the cable shield (grounding resistance ＜1Ω). Use an oscilloscope to monitor the output waveform. Abnormal waveform distortion may indicate magnet demagnetization or sensor aging, which requires timely calibration.
