Features:
- Extended Linear Range for Critical Measurements
- Full Armor & Extreme Temperature Durability
- True Interchangeability – No Calibration Matching
The Bently Nevada 330702-00-25-10-02-00 offers a 4.0 mm linear range – 60% longer than standard 8 mm probes. This enables accurate axial thrust position and differential expansion monitoring on large steam turbines and compressors, where traditional probes would lose signal linearity.
With an AISI 304 stainless steel case and full armor, the Bently Nevada 330702-00-25-10-02-00 withstands mechanical abrasion, high vibration, and temperatures from -52°C to +177°C. The FluidLoc™ cable option (selectable) further prevents oil wicking, making it ideal for turbine bearing housings.
Unlike legacy systems, the Bently Nevada 330702-00-25-10-02-00 requires no individual probe-to-proximitor calibration. Any 3300 XL 11 mm component can be swapped directly, reducing spare parts inventory by over 70% and cutting repair downtime from hours to minutes.
The 330702-00-25-10-02-00 Bently Nevada 3300 XL 11 mm Proximity Probes may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Pressure Seal Integrity – The Viton O-ring seals differential pressure across the probe tip. Do not expose the probe below -34°C before installation; otherwise, the seal may crack prematurely.
- Electrostatic Discharge (ESD) Precautions – Although the Proximitor sensor has internal ESD protection, proper grounding during handling is required to prevent damage to the connector and internal electronics.
- Installation Drawing Mandate – For hazardous area use, install strictly per Bently Nevada drawings 141092 (intrinsic safety) or 140979 (non-incendive). Deviation invalidates approvals.
- FluidLeak Responsibility – The customer is responsible for containing any process fluid leakage if the probe seal fails. Bently Nevada does not cover leakage damage under warranty or service plans.
- ATEX & IECEx (Ex ia IIC T5…T1 Ga) – Certified for Zone 0 gas hazardous areas, allowing direct installation inside bearing housings without explosion-proof enclosures.
- cNRTLus for North America – Approved for Class I, Division 1 & 2, Groups A–D (flammable gases) and Class II/III (combustible dusts) per NEC/CEC.
- Functional Safety (SIL 2/3) – Capable of use in safety-instrumented systems (SIS) up to SIL 3 with hardware fault tolerance (HFT=1), compliant with IEC 61508/61511.
- Environmental & Material Compliance – RoHS and China RoHS compliant (EFUP 15 years); tested to IEC 68-2-3 for damp heat and 100% condensing humidity.
- Axial (Thrust) Position Monitoring – Provides ±2 mm linear measurement range for thrust bearing wear detection on gas and steam turbines, preventing catastrophic rotor-stator rub.
- Differential Expansion (Ramp Measurement) – Essential for steam turbine startup/shutdown cycles; captures casing-to-rotor growth differences with 4.0 mm range.
- Rod Drop / Rod Position Monitoring – Used in reciprocating compressors to detect valve or piston rod settling, enabling predictive maintenance before mechanical failure.
- Keyphasor™ & Zero Speed Detection – Generates precise once-per-turn timing signals for phase analysis, balancing, and speed control in high-speed turbomachinery.
