Technical Specifications

Installation Guidance

Maintain correct air gap alignment between probe tip and shaft target surface to ensure linear signal response within calibration range. Install with controlled torque to avoid mechanical stress on probe housing.

Ensure minimum cable bend radius is not less than 50 mm to prevent signal degradation and insulation fatigue.

Apply proper grounding through Proximitor system earth reference to eliminate electromagnetic interference in high-noise turbine environments.

Verify full compatibility with 3300 XL extension cables before energizing system to avoid impedance mismatch.

Engineering Advantages

The probe performs reliably under extreme thermal cycling, high vibration density, and oil-contaminated environments commonly found in turbines and compressors. Its stainless-steel sensing architecture ensures long-term stability without signal drift.

It integrates seamlessly with Bently Nevada TSI platforms and GE-compatible monitoring systems, including legacy 3500 protection racks and modern DCS environments such as Experion PKS.

Engineers rely on its stable eddy current response to protect critical rotating assets, reduce unplanned downtime, and maintain continuous operational safety in high-value industrial processes.
