The Bently Nevada 330702-00-24-10-11-05 represents a specialized configuration within the 3300 XL series of 11 mm eddy-current proximity probes. This model distinguishes itself through its armored cable construction and FluidLoc cable technology, which together provide superior protection against mechanical abrasion, moisture ingress, and chemical exposure. It features a 1/2-20 UNF thread with a 2.4-inch overall case length and a 1.0-meter total cable length. Additionally, the miniature coaxial ClickLoc connector comes with a connector protector to shield the interface from contaminants. With Multiple Approvals (Option 05) , this probe meets rigorous international safety standards, making it a prime choice for refineries, offshore platforms, and chemical plants where reliability is paramount.
Electrical Characteristics
The probe's DC resistance from the center conductor to the outer conductor measures 5.9 ± 0.5 ohms for the 1.0-meter configuration. Meanwhile, the cable maintains a 75 Ω triaxial impedance to preserve signal fidelity over its length. This resistance range is factory-calibrated for optimal compatibility with 3300 XL proximity drivers.
Mechanical Dimensions
Unthreaded Length Option: 00 = 0.0 inches
Overall Case Length Option: 24 = 2.4 inches
Total Length Option: 10 = 1.0 meter (3.3 feet)
Connector Option: 11 = Miniature coaxial ClickLoc connector with connector protector, FluidLoc cable
Agency Approval Option: 05 = Multiple Approvals (ATEX, CSA, IECEx compliant)
Materials and Construction
Probe Tip: Polyphenylene sulfide (PPS) – delivers excellent resistance to chemicals and wear.
Probe Case: AISI 304 stainless steel (SST) – ensures long-term corrosion resistance in aggressive environments.
Cable Type: FluidLoc cable – features a specialized jacketing system that prevents fluid migration along the cable core, protecting the sensing electronics.
Cable Insulation: Fluoroethylene propylene (FEP) – maintains electrical integrity across the full temperature spectrum.
The armor on this Bently Nevada 330702 probe provides mechanical protection against crushing, cutting, and abrasion during installation and operation. This is particularly valuable in high-traffic machinery areas where cables may be exposed to physical stress. Furthermore, the FluidLoc cable design incorporates a proprietary sealing mechanism that blocks oil, water, and process fluids from traveling along the cable and reaching the connector or driver. This feature significantly extends the probe's service life in wet or corrosive applications. The minimum bend radius for this armored cable remains 25.4 mm (1.0 inch) , identical to the unarmored version, preserving installation flexibility.
Temperature Range
Operating and Storage: -51°C to +177°C (-60°F to +351°F)
However, sustained exposure below -34°C (30°F) may shorten the pressure seal's operational lifespan.
Pressure Sealing
The probe seals differential pressure between the tip and case via a Viton® O-ring. Nevertheless, Bently Nevada does not perform pressure testing on individual units prior to shipment. For applications that require certified pressure seal validation, please contact the custom design department for additional testing.
Thread and Torque Specifications
Case Thread: 1/2-20 UNF
Maximum Thread Engagement: 0.750 inches
Maximum Rated Torque: 45.2 N•m (400 in•lb)
Recommended Installation Torque: 15.2 N•m (133 in•lb)
Connector-to-Connector Torque: Finger tight (maximum 0.565 N•m / 5 in•lb)
Minimum Bend Radius: 25.4 mm (1.0 inch) – applies to both armored and unarmored configurations.
The Option 05 approval package certifies this 330702 model for use in hazardous locations worldwide. Specific approvals include:
ATEX – for European explosive atmosphere compliance
CSA – for Canadian safety certification
IECEx – for international hazardous area standards
These certifications make the probe suitable for Zone 0, Zone 1, and Zone 2 installations (gas) as well as Zone 20, 21, and 22 (dust), depending on the specific certification details. Always confirm that the approval scope matches your exact zone classification before installation.
First, inspect the mounting hole threads to ensure they are clean and undamaged, matching the 1/2-20 UNF specification. Next, carefully thread the Bently Nevada 330702-00-24-10-11-05 probe into position, applying the recommended torque of 15.2 N•m – do not exceed the 45.2 N•m maximum rating to avoid thread galling or internal component stress. Then, attach the ClickLoc connector to the mating extension cable; the connector protector should remain securely in place to shield the interface from dirt and moisture. Use only finger pressure when making the connection – tools are not required and may compromise the locking mechanism. Finally, route the armored cable with a minimum bend radius of 25.4 mm; although the armor provides extra protection, sharp bends can still damage internal conductors. For optimal system accuracy, pair this probe with genuine Bently Nevada extension cables and drivers that support the FluidLoc interface.

1. What makes FluidLoc cable different from standard cable?
FluidLoc cable incorporates a specialized sealing system that prevents liquids from migrating along the cable core. This is critical in applications where the probe is exposed to oil, coolant, or process fluids that could otherwise reach the connector or driver.
2. How does the armor affect cable flexibility?
The armor provides substantial mechanical protection while maintaining a bend radius of 25.4 mm, which matches the unarmored version. This allows routing in tight spaces without sacrificing durability.
3. What is the total cable length of the 330702-00-24-10-11-05?
This model comes with a 1.0-meter (3.3 feet) total cable length. If a longer reach is required, consider the 5.0 or 9.0 meter options with FluidLoc cable.
4. Can I use this probe in a continuously submerged environment?
The FluidLoc cable and Viton O-ring seal provide excellent fluid resistance. However, Bently Nevada does not certify these probes for permanent submersion. For fully submersible applications, please consult the custom design department for specialized solutions.
5. What approvals are included in the Option 05 certification?
Option 05 includes ATEX, CSA, and IECEx approvals, enabling installation in hazardous areas across North America, Europe, and other regions that recognize these standards. Verify the specific certificate details for your zone classification requirements.
