3. Function and Product Positioning

Core Functions

• Radial Vibration Measurement: Detects high-frequency radial runout of the rotating shaft, used to judge equipment faults such as unbalance, misalignment and bearing damage.

• Axial Thrust Monitoring: Tracks axial displacement of the shaft, monitors wear status of thrust bearings and prevents axial collision failure.

• Static Gap Detection: Measures static installation gap between probe and shaft to ensure the whole system works within linear range.

• Speed and Phase Detection: Cooperates with keyphasor notch on the shaft to collect rotational speed and phase reference signals for rotor dynamic analysis.

• Signal Transmission: Stably transmits high-frequency induction signals through shielded cable, avoiding signal attenuation and external interference.

Operational Features

• Interchangeability: All probes, cables and proximitors of 3300 XL series are mutually interchangeable without re-calibration, simplifying on-site maintenance and spare parts management.

• Wide Temperature Adaptation: Maintains stable electrical performance in high-temperature equipment cabins and normal ambient environments.

• Fully Sealed Structure: No internal exposed components, effectively preventing dust, moisture and oil from entering to cause failure.

• Flexible Layout: Matched with different lengths of extension cables to adapt to various installation distances between measuring points and control cabinets.

• Long-term Stability: Low drift design ensures consistent measurement accuracy during long-term continuous operation.
