Thermal Power Generation
Measuring rotor differential expansion in high-pressure and low-pressure cylinders of supercritical steam turbines.
Nuclear Power Industry
Monitoring axial thermal displacement along the multi-meter shafting of main saturated steam turbines in nuclear power plants.
Hydroelectric Power Generation
Monitoring dynamic runout and large shaft vibration of thrust bearings in giant vertical hydro-generator units.
Petrochemical Refining
Monitoring axial rotor float of large charge gas compressors in ethylene plants.
Iron and Steel Metallurgy
Monitoring axial expansion of large blast furnace blower rotors in blast furnace Top-pressure Recovery Turbine (TRT) systems.
Cement Manufacturing
Monitoring axial float of high-speed shafts in main drive gearboxes of large clinker rotary kilns.
When using 330878-51-05, notice the calibration material and signal cable protection. The key involves ensuring the system strictly matches the 50mm probe and specific target material (usually AISI 4140 steel) to prevent linear thermal drift, and signal terminal wiring stays clear of high-voltage power cables. Also, the proximitor metal housing requires secure grounding, and the -24Vdc power supply must remain stable to avoid measurement waveform distortion.
