The Bently Nevada 330701-00-10-90-01-05 is a premium 11 mm proximity probe from the industry-standard 3300 XL series. This model is specifically configured with a 1/2-20 UNF thread without armor, a 1.0-inch overall case length, and an extended 9.0-meter FEP-insulated triaxial cable. Furthermore, it features a miniature coaxial ClickLoc connector equipped with a connector protector to safeguard against contamination and mechanical damage. A key differentiator for this variant is the Multiple Approvals (Option 05) , making it suitable for installations requiring rigorous safety and regulatory certifications. Consequently, this probe excels in demanding environments such as oil and gas, power generation, and chemical processing.
Electrical Characteristics
The probe's DC resistance from the center conductor to the outer conductor is 8.5 ± 1.1 ohms for the 9.0-meter length. Meanwhile, the cable maintains a 75 Ω triaxial impedance to ensure stable signal transmission over the extended distance. This resistance value is specifically calibrated for the 9.0-meter configuration to work seamlessly with 3300 XL drivers.
Mechanical Dimensions
Unthreaded Length Option: 00 = 0.0 inches
Overall Case Length Option: 10 = 1.0 inch
Total Length Option: 90 = 9.0 meters (29.5 feet)
Connector Option: 01 = Miniature coaxial ClickLoc connector with connector protector, standard cable
Agency Approval Option: 05 = Multiple Approvals (includes ATEX, CSA, and IECEx certifications)
Materials and Construction
Probe Tip: Polyphenylene sulfide (PPS) – offers outstanding chemical and wear resistance.
Probe Case: AISI 304 stainless steel (SST) – delivers excellent corrosion protection in harsh environments.
Cable Insulation: Fluoroethylene propylene (FEP) – ensures reliable performance across extreme temperature ranges.
Temperature Range
Operating and Storage: -51°C to +177°C (-60°F to +351°F)
However, exposure below -34°C (30°F) may accelerate degradation of the pressure seal material.
Pressure Sealing
This probe is engineered to seal differential pressure between the tip and the case using a Viton® O-ring. Nevertheless, Bently Nevada does not pressure-test units before shipping. For applications that demand certified pressure seal verification, please contact the custom design department for additional testing services.
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 cable configurations.
The Option 05 designation signifies that this Bently Nevada 330701 model carries multiple agency approvals, including:
ATEX for hazardous area operation in Europe
CSA for Canadian safety standards
IECEx for international explosive atmosphere compliance
These certifications make this probe an excellent choice for global projects where regulatory compliance is mandatory. Always verify that the specific approval covers your intended hazardous zone classification before installation.
First, confirm that the target shaft surface is smooth and free from oil, dirt, or scratches. Next, thread the Bently Nevada 330701-00-10-90-01-05 probe into the mounting hole using the recommended torque of 15.2 N•m – do not exceed the 45.2 N•m maximum rating. Then, connect the ClickLoc connector to the extension cable; the connector protector should remain attached to shield the interface from dust and moisture. Use only finger pressure when mating the connector – tools are unnecessary and could damage the locking mechanism. Finally, route the 9.0-meter cable with a bend radius of at least 25.4 mm to avoid signal attenuation or internal conductor fracture. For optimal system performance, always pair this probe with genuine Bently Nevada extension cables and drivers that match the 9.0-meter total length configuration.

1. What is the total cable length of the 330701-00-10-90-01-05?
This model features a 9.0-meter (29.5 feet) triaxial cable, which is the longest option available for 3300 XL probes. It suits installations where the driver must be positioned far from the measurement point.
2. What does the "Multiple Approvals" option (05) include?
The Option 05 certification package includes ATEX, CSA, and IECEx approvals. This allows the probe to be used in hazardous areas globally, provided the specific zone classification matches the certification scope.
3. How does the connector protector benefit installation?
The connector protector safeguards the ClickLoc interface from dirt, moisture, and accidental impacts during handling. It also helps maintain signal integrity in dusty or wet environments.
4. Can I use this 9.0-meter probe with a standard 3300 XL driver?
Yes, but ensure the driver is properly calibrated for the 9.0-meter total length. The DC resistance of 8.5 ± 1.1 ohms must be matched with the driver's input characteristics for accurate linear output.
5. What thread size does this probe use, and is it compatible with existing mounts?
This model uses a 1/2-20 UNF thread. Please verify that your existing mounting fixture or adapter matches this thread specification. If you have 5/8-18 mounts, consider the 330708 or 330707 variants instead.
