The Bently Nevada 330701-00-10-10-11-05 is a precision-engineered 11 mm proximity probe from the trusted 3300 XL series. Manufactured in the U.S.A., this probe delivers non-contact vibration and position measurements for critical rotating machinery. Its 1/2-20 UNF thread, 1.0-inch overall case length, and 1.0-meter total length make it suitable for various installation configurations. Additionally, the miniature coaxial ClickLoc connector with connector protector ensures secure signal transmission, while the FluidLoc cable option provides enhanced fluid resistance. Consequently, this probe is an excellent choice for turbine, compressor, and pump monitoring applications.
The 330701-00-10-10-11-05 offers robust construction and consistent electrical performance. Its design emphasizes reliability in harsh industrial environments while maintaining measurement accuracy.
Electrical Characteristics
Probe DC Resistance: The RPROBE measures 5.9 ± 0.5 Ω for the 1.0-meter length, ensuring proper signal integrity between the probe tip and the proximitor.
Cable Specification: The probe uses 75 Ω triaxial cable with fluoroethylene propylene (FEP) insulation, providing excellent dielectric properties and signal stability.
Linear Range: This 11 mm probe offers a 2 mm (80 mils) linear range, beginning at approximately 0.25 mm from the target and extending to 2.3 mm (10 to 90 mils).
Recommended Gap Setting: For radial vibration measurements, we recommend a -9 Vdc gap setting, which corresponds to approximately 1.27 mm (50 mils).
Mechanical Specifications
Probe Tip Material: The tip uses Polyphenylene sulfide (PPS), which offers excellent chemical resistance and dimensional stability at elevated temperatures.
Probe Case Material: AISI 304 stainless steel (SST) provides superior corrosion resistance and mechanical strength for demanding environments.
Thread Specification: The probe case features a 1/2-20 UNF thread with a maximum thread engagement length of 0.750 inches.
Case Torque Ratings: The maximum rated torque is 45.2 N•m (400 in•lb), while we recommend 15.2 N•m (133 in•lb) for proper installation without causing damage.
Connector Torque: The miniature coaxial ClickLoc connector requires finger-tight engagement initially, with a maximum torque of 0.565 N•m (5 in•lb).
Minimum Bend Radius: The cable maintains a minimum bend radius of 25.4 mm (1.0 in), with or without stainless steel armor.
Environmental Specifications
Temperature Range: The 330701-00-10-10-11-05 operates and stores reliably from -52°C to +177°C (-62°F to +351°F). However, exposing the probe to temperatures below -34°C (30°F) may cause premature failure of the pressure seal.
Pressure Capability: The probe uses a Viton® O-ring to seal differential pressure between the probe tip and case. Please contact our custom design department if your application requires pressure testing prior to shipment.
Agency Approvals
This model features the "05" multiple approvals option, including CSA, ATEX, and IECEx certifications. Furthermore, it complies with FCC Part 15, EMC Directive 2014/30/EU, and RoHS Directive 2011/65/EU. It also meets maritime classification rules and is certified for functional safety up to SIL 3 with HFT = 1.
Mounting and Positioning
The Bently Nevada 330701-00-10-10-11-05 requires careful installation to achieve optimal performance. First, verify that the mounting surface is clean and free from debris. Next, thread the probe into the mounting hole using the 1/2-20 UNF threads. Apply the recommended torque of 15.2 N•m (133 in•lb) to secure the probe without over-tightening. Additionally, ensure the minimum bend radius of 25.4 mm is maintained when routing the cable to prevent internal damage.
Connector Handling
The miniature coaxial ClickLoc connector provides a secure, positive-locking connection. Tighten the connector finger-tight initially, then apply up to 0.565 N•m (5 in•lb) maximum torque. The connector protector shields the connection from contamination and mechanical stress, enhancing long-term reliability.
Gap Setting and Calibration
For radial vibration monitoring, set the probe gap to -9 Vdc, which corresponds to approximately 1.27 mm (50 mils). This setting places the probe within the linear range of the measurement system. Use a precision gap measurement tool or voltage meter to verify the gap setting during installation.

1. What is the difference between this 11 mm probe and the 8 mm version?
The Bently Nevada 330701-00-10-10-11-05 offers a larger tip diameter and different thread size (1/2-20 UNF) compared to the 8 mm probe (typically M8 or 3/8-24). Consequently, it is better suited for applications requiring larger mounting hardware and specific mechanical interfaces.
2. Can I use this probe with existing 3300 XL extension cables?
Yes, the 330701-00-10-10-11-05 is fully compatible with 3300 XL series extension cables. The miniature coaxial ClickLoc connector interfaces directly with matching extension cable connectors.
3. What is the significance of the "05" approval option?
The "05" indicates multiple approvals including CSA, ATEX, and IECEx, making this 3300 XL probe suitable for installation in hazardous locations worldwide.
4. Why is the temperature below -34°C a concern?
Exposing the probe to temperatures below -34°C (30°F) may cause premature failure of the Viton® O-ring pressure seal. Therefore, we recommend avoiding such conditions or consulting our team for special low-temperature sealing solutions.
5. What is the maximum length of probe cable available?
The 3300 XL 11 mm probes are available in total lengths of 1, 5, or 9 meters. The 330701-00-10-10-11-05 specifically features a 1.0-meter length for shorter-distance installations.
