330141-08-90-12-05 Bently Nevada 3300 XL 8 mm Probe, 9.0 m

Product Overview: Bently Nevada 330141-08-90-12-05

The Bently Nevada 330141-08-90-12-05 is a 3300 XL 8 mm probe with armor, engineered for exact displacement and vibration measurement in rotating machinery. As part of the 3300 XL series, this probe delivers engineering-grade precision through its patented TipLoc and CableLoc designs. The 8 mm probe body provides a thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged sensor. Consequently, it withstands physical abuse better than smaller-diameter probes. The FluidLoc cable option prevents oil and other liquids from leaking through the cable interior, which protects machine environments. This probe is made in the U.S.A. and carries CSA, ATEX, and IECEx approvals for use in hazardous areas.

Performance and Reliability

The 330141-08-90-12-05 excels in harsh industrial environments. Its 8 mm probe tip uses PPS encapsulation for mechanical strength. Meanwhile, the stainless steel case resists corrosion. The patented CableLoc design provides 330 N (75 lbf) pull strength, securing the cable to the probe tip. This prevents accidental disconnection. Additionally, the FluidLoc cable option blocks oil leakage, which is critical for machine health. The probe operates reliably from -52°C to +177°C. However, avoid exposing it below -34°C (-30°F) to prevent pressure seal failure. The probe seals differential pressure with a Viton O-ring, but it is not pressure tested prior to shipment. For humidity, it shows less than 3% average scale factor change after 56 days at 93% humidity.

Applications and Use Cases

This probe suits turbomachinery, compressors, and pumps where precise radial vibration monitoring is essential. For instance, in a petrochemical plant, the FluidLoc cable prevents oil seepage that could contaminate the sensor. In power generation, the 9.0 m length allows flexible mounting away from hot zones. The armored cable adds protection against mechanical damage. Because of its ATEX and IECEx approvals, it can be installed in hazardous areas. The 8 mm probe diameter offers optimal robustness against physical abuse, making it ideal for rugged field conditions.

Installation and Integration

Mount the probe using standard 8 mm probe mounting hardware. Ensure the target surface is clean and perpendicular to the probe tip. The miniature coaxial ClickLoc connector mates with compatible extension cables. When integrating into a 3300 XL monitoring system, verify that the total system length matches the probe length. The 9.0 m probe requires a 9.0 m extension cable to maintain calibrated scale factor. For hazardous area installations, follow local codes and the approval documentation. Always confirm cable and connector compatibility with AutoDCSTech before ordering.
