Bently Nevada 330876-02-10-00-00 3300 XL 50mm Proximity Probe
Product Introduction
The 330876-02-10-00-00 belongs to the reliable 3300 XL series. Bently Nevada created this 50 mm proximity probe for the most demanding turbine environments. It delivers accurate measurements continuously, even under extreme heat.
Additionally, this probe includes both front and rear seals. These seals stop moisture from entering the probe tip effectively. For instance, the High Temperature FluidLoc cable comes standard on all 50 mm probes and provides excellent moisture protection. Furthermore, the high-temperature ClickLoc connectors are standard on both the probe and any extension cable.
Technical Specifications
This 330876-02-10-00-00 model offers a total probe length of 1.0 meter (3.3 feet). The probe case type option is -02, which means M14x1.5 metric thread. Its armor option is -00 for High Temperature FluidLoc Cable. The agency approval option is -00, indicating no specific approvals required.
Probe Case Thread: M14x1.5 (metric)
Maximum Length of Thread Engagement: 21 mm
Overall Case Diameter: 1.99 inches (50.5 mm)
Case Material: AISI 304 stainless steel (SST)
Tip Material: Polyphenylene Sulfide (PPS)
Meanwhile, the DC resistance from center to coaxial conductor measures 6.4 ± 0.5 Ω. This lower resistance value applies specifically to the 1.0 meter probe length. The probe cable uses 75 Ω triaxial, PFA insulated FluidLoc construction for reliable signal integrity.
Environmental and Mechanical Ratings
The 3300 XL 50 mm probe maintains consistent performance in harsh conditions. Its standard operating and storage temperature ranges from -35°C to +200°C (-31°F to +392°F). For short-term situations, it withstands +250°C (+482°F) for less than 24 hours.
Therefore, this probe works perfectly in steam turbine DE environments. The straight exit case style features M14x1.5 metric threads and includes a locknut with predrilled safety wire holes. Additionally, the ClickLoc connector on the probe lead has a removable collar. This collar simplifies routing the cable through tight clearances.
Installation Guidelines
Proper installation ensures maximum performance and longevity. First, confirm the mounting hole has clean, undamaged metric threads. The maximum length of thread engagement is 21 mm. Never exceed this value.
Next, use the disposable connector protector installation tool. This tool keeps all connectors free from contamination during setup. Meanwhile, each probe and cable comes with connector protectors already installed. These protectors prevent dirt and moisture from entering the ClickLoc connectors.
Finally, route the cable carefully through tight spaces. The removable collar on the 330876-02-10-00-00 probe lead makes this task much easier. Always secure the cable away from moving parts or direct heat sources above the rated temperature.

Frequently Asked Questions (FAQ)
1. What thread type does this probe use?
The 330876-02-10-00-00 uses M14x1.5 metric threads. This is different from the ½-20 English thread version. Make sure your mounting hole matches this metric specification before ordering.
2. Why does this 1.0 meter probe have different DC resistance?
The DC resistance from center to coaxial conductor is 6.4 ± 0.5 Ω for the 1.0 meter length. Shorter cable length naturally results in lower resistance compared to the 9.0 meter version, which measures 8.9 ± 1.1 Ω.
3. Can this probe withstand steam turbine DE environment moisture?
Yes, the 3300 XL 50 mm probe has both front and rear seals. Additionally, the High Temperature FluidLoc cable prevents moisture from entering the probe tip. These features make it ideal for steam turbine DE applications.
4. What is the maximum continuous operating temperature?
This 330876-02-10-00-00 probe runs continuously at 200°C (392°F). It also tolerates intermittent peaks up to 250°C (482°F) for less than 24 hours without losing accuracy.
5. Does the probe include connector protectors?
Yes, each 330876-02-10-00-00 probe comes with connector protectors installed. Furthermore, a disposable installation tool is included to ensure contamination-free connections during the initial setup.
