5. Product Description

The 330104-01-05-50-02-00 probe is engineered for precise, non-contact measurement of radial shaft vibration and displacement.

It operates on eddy current sensing principles, producing an analog voltage proportional to the distance between the probe tip and a conductive shaft surface. The non-contact method eliminates wear, reduces maintenance, and ensures long-term stability.

The 2-meter cable allows the probe to connect to remotely located monitoring electronics, making it suitable for turbines, compressors, pumps, and motors where control panels are not adjacent to the measurement point. The stainless steel construction and IP67 rating protect the probe against dust, oil, vibration, and moderate temperature fluctuations.

6. Applications

The probe is widely applied in industrial rotating machinery monitoring, including:

• Steam and gas turbines
• Centrifugal and reciprocating compressors
• Industrial pumps
• Electric motors
• Gearboxes

Typical functions include:

• Radial shaft vibration measurement
• Axial displacement and rotor position monitoring
• Phase and speed reference (keyphasor signals)
• Condition monitoring for predictive maintenance
• Integration into machinery protection systems

Its 2-meter cable is optimal for installations where electronics cabinets are located at some distance from the shaft, ensuring reliable data transmission.

7. Product Advantages

• Non-contact measurement: No mechanical wear, reducing maintenance.
• High accuracy and repeatability: Stable analog output.
