Description
The Bently Nevada 330191-02-10-10-00 is a specialized 3300 XL 8 mm Extended Temperature Range (ETR) Proximity Probe. It is engineered to measure vibration, dynamic shaft motion, and position displacement in extreme-temperature industrial rotating machinery environments (such as heavy gas turbines and high-heat compressors) where standard proximity probes fail.

Engineering and Field Integration Notes
When installing ETR probes like the 330191 series in high-temperature machinery, managing thermal expansion and cable routing is critical.
Integration Guidelines
- Thermal Expansion Allowance: Account for thermal growth of the turbine or compressor casing during startup when setting the initial cold gap voltage (typically targeting -9 V DC linear center point).
- Armor Protection: The
-02stainless steel armor option safeguards the FEP insulated coaxial cable against mechanical wear, hot fluid exposure, and sharp edges inside harsh machine terminal boxes. - System Matching: Ensure the ETR probe is paired with a compatible 3300 XL ETR Proximitor sensor calibrated specifically for extended temperature system curves to prevent output linearity errors.
