The 330701-00-20-40-02-00 belongs to the Bently Nevada 3300 XL 11 mm transducer family. This probe provides non-contact vibration and position measurement through eddy current technology. Specifically, the 11 mm tip design offers a longer linear range than standard 8 mm systems. Therefore, engineers select this model for axial thrust position, differential expansion, and Keyphasor reference measurements where extended range is essential.
Each suffix in the model number defines a specific configuration. First, 330701 indicates the 11 mm probe body with 1/2-20 UNF thread and no armor. Next, 00 specifies a zero-inch unthreaded length. Moreover, 20 sets the overall case length at 2.0 inches. The 40 code defines a total system length of 4.0 metres. Additionally, 02 designates a miniature coaxial ClickLoc connector with standard cable. Finally, 05 confirms multiple agency approvals for hazardous area use.
| Parameter | Value |
|---|---|
| Probe DC Resistance | 7.2 Ω ± 0.8 (at 4.0 m) |
| Linear Range | Approximately 4 mm |
| Sensitivity | 3.94 V/mm (100 mV/mil) |
| Connector Type | Miniature coaxial ClickLoc |
| Cable Type | 75 Ω triaxial, FEP insulated |
The probe tip uses polyphenylene sulfide (PPS) for chemical resistance. Meanwhile, the case is machined from AISI 304 stainless steel for durability in industrial atmospheres. The operating and storage temperature range spans -52°C to +177°C (-62°F to +351°F). However, exposure below -34°C may cause premature pressure seal failure. Besides temperature, users must observe the 25.4 mm (1.0 in) minimum bend radius to prevent cable damage. The Viton O-ring seals differential pressure between tip and case, though probes ship without individual pressure testing.
Proper mounting ensures measurement accuracy and long service life. First, verify the target material and set the correct gap according to the Proximitor Sensor specifications. Next, apply the recommended case torque of 15.2 N·m (133 in·lb). Do not exceed the maximum rating of 45.2 N·m. Furthermore, the maximum thread engagement for the 1/2-20 UNF case is 0.750 inch. When routing the cable, maintain the minimum bend radius and secure connections finger-tight at the connector. The ClickLoc mechanism locks automatically to prevent loosening from vibration.

Q1: Does this probe work with existing 3300 XL Proximitor Sensors?
A: Yes. The 330701-00-20-40-02-00 mates directly with standard 3300 XL 11 mm extension cables and Proximitor Sensors. Always verify the complete loop length matches the system configuration.
Q2: What is the difference between suffix 02 and suffix 11 cable options?
A: Suffix 02 uses standard FEP cable. Suffix 11 adds the FluidLoc feature, which prevents oil from migrating through the cable interior.
Q3: Can I order this probe with armor?
A: No. The 330701 base model is unarmored. For armored 11 mm probes, inquire about the 330702 series.
Q4: How do you ship this item?
A: We ship worldwide via FedEx, UPS, and DHL. All shipments include tracking and insurance.
Q5: Is the probe tip replaceable in the field?
A: No. The PPS tip bonds permanently to the probe body. Replace the entire 330701-00-20-40-02-00 assembly if the tip sustains damage.
