Product Introduction
When probe failures cause costly downtime and unreliable readings, the Bently Nevada 330141-08-50-11-05 delivers robust reliability. This 8 mm probe is part of the 3300 XL series and features an armored construction designed to withstand physical abuse and harsh environments. With patented TipLoc and CableLoc technologies, the probe minimizes common failure modes such as tip detachment and cable breakage, ensuring consistent performance in critical rotating machinery monitoring.
Technical Specifications Breakdown
The Bently Nevada 330141-08-50-11-05 offers precision measurement with an incremental scale factor of 7.87 V/mm (200 mV/mil) with ±5% interchangeability error for 5-meter systems. Its probe DC resistance is 8.73 Ω ±0.50 at 5.0 meters, ensuring stable signal transmission. The probe tip is made of polyphenylene sulfide (PPS) for superior encapsulation and chemical resistance, while the case is AISI 303 or 304 stainless steel. The unit operates over a wide temperature range, from -52°C to +177°C standard, with extended range up to +218°C for the tip and +260°C for the cable. Deviation from best fit straight line is less than ±0.025 mm for standard systems, providing high linearity.

Industry Applications
This probe excels in vibration monitoring for turbines, compressors, pumps, and other rotating equipment. In oil and gas refineries, the armored 330141-08-50-11-05 resists physical damage from debris and washdowns. In power generation, its FluidLoc cable option prevents oil leakage from bearing housings, reducing maintenance costs. The Bently Nevada 330141-08-50-11-05 also suits pulp and paper mills where high humidity and temperature extremes challenge standard probes.
Installation & Setup Guidance
Mount the 330141-08-50-11-05 using the recommended mounting bracket, ensuring proper gap and target surface. The probe is designed for use with the 5 meter Proximitor sensor only. When using the ClickLoc connector, secure the connector protector to prevent accidental disconnection. For FluidLoc installations, verify that the cable gland seals properly to contain oil. Avoid exposing the probe to temperatures below -34°C to maintain the pressure seal integrity.
Maintenance & Reliability
Regularly inspect the probe cable for wear near the entry point. The CableLoc design provides 330 N pull strength, but environmental abrasion can still occur. Check the O-ring seal periodically if the probe is in a pressurized environment. The Viton O-ring is designed for differential pressure sealing but is not tested prior to shipment. Humidity testing shows less than 3% ASF change after 56 days at 93% RH, demonstrating excellent moisture resistance. The robust 8 mm construction and TipLoc molding reduce the need for frequent recalibration.
Selection Guide & Purchasing Advice
When ordering the Bently Nevada 330141-08-50-11-05, confirm your system compatibility, especially the 5-meter Proximitor requirement. The included FluidLoc cable option is recommended for oil-wetted environments. For applications requiring extended temperature range, ensure the probe version matches. PLC Source PRO stocks this exact model with traceability and fast shipping to minimize your downtime. Verify the connector type (Code 11) and agency approval (Code 05) match your site requirements.
