Description
Engineered for high-reliability machinery monitoring, the Bently Nevada 330703-010-075-10-01-00 functions as a rugged non-contacting proximity probe. Designed for the 3300 XL 11 mm series, this transducer system measures static (position) and dynamic (vibration) distances between the probe tip and the observed target, facilitating predictive maintenance for critical rotating equipment.
The system comprises an 11 mm probe tip, an M14 x 1.5 metric threaded housing, and a built-in triaxial cable. The probe is engineered to operate in harsh industrial environments with extreme temperature variations and exposure to aggressive lubricants. Using a ClickLoc coaxial connector equipped with a connector protector, the probe ensures a stable connection to extension cables while resisting moisture and environmental contamination.
Features
- Non-contact, high-precision measurement of vibration and axial position.
- Polyphenylene sulfide (PPS) probe tip for superior chemical resistance and mechanical durability.
- AISI 304 stainless steel (SST) case for robust physical protection.
- Triaxial cable structure with fluoroethylene propylene (FEP) insulation to minimize signal loss and interference.
- ClickLoc miniature coaxial connector with an integrated protector for secure connections in high-vibration environments.
- Designed for direct compatibility with the Bently Nevada 3300 XL 11 mm Proximitor Sensor system.
Applications
- Steam turbines and gas turbines
- Centrifugal compressors and axial compressors
- High-pressure water pumps and generators
- Hydroelectric power turbines
- Heavy-duty gearboxes and fans

Installation Guidelines
-
Target Clearance: Maintain minimum clearance to adjacent metal structures to prevent target cross-talk and calibration errors.
-
Torque Limits: Do not exceed the maximum recommended mounting torque for the M14 x 1.5 stainless steel thread housing.
-
Cable Routing: Ensure the minimum bend radius of the FEP insulated probe cable is not compromised during installation inside conduit or junction boxes.
-
Grounding: Ensure the probe housing is properly grounded through the machine casing, while isolated from unwanted electrical loops.
