5. Product Description
The 330104‑01‑05‑50‑01‑RU is designed for reliable, continuous, non‑contact measurement of shaft vibration amplitude and radial displacement in rotating equipment.
The proximity probe uses eddy current sensing technology to generate an electrical signal proportional to the distance between the probe tip and the metallic shaft surface. This non‑contact method removes mechanical wear and friction, ensuring long‑term stability and reduced maintenance.
The 0.5‑meter system cable allows flexible placement of the monitoring electronics relative to the sensing point, and its stainless steel construction with oil‑resistant cable jacket ensures resilience in challenging industrial environments with vibration, dust, and contaminant exposure.
Threaded mounting and standardized connector design allow consistent installation and straightforward serviceability. The result is a durable, stable sensor that forms the foundation of effective machinery protection and condition monitoring systems.
6. Applications
The 330104‑01‑05‑50‑01‑RU proximity probe is suitable for a wide range of rotating machinery monitoring applications, including:
- Steam turbine vibration and rotor monitoring
- Gas turbine shaft position and vibration measurement
- Centrifugal and reciprocating compressor monitoring
- Industrial pump vibration analysis
- Electric motor condition monitoring
- Gearbox radial displacement sensing
Typical monitoring functions include:
- Radial shaft vibration amplitude
- Axial displacement measurement
- Rotor position tracking
- Phase and keyphasor reference signals
- Condition monitoring feeding predictive maintenance systems
Its moderate cable length and sturdy design make it well‑suited for installations where the sensor needs to be close to the monitoring electronics and in environments subject to oil, dust, and mechanical vibration.
