The Bently Nevada 330876-02-10-01-05 belongs to the 3300 XL 50 mm Proximity Probe family. This probe handles the most demanding steam turbine DE (driver end) environments. It maintains accurate measurements while exposed to high temperatures up to 200°C (392°F). The device can also survive intermittent spikes up to 250°C (482°F) for short periods.
This probe includes both front and rear seals for superior moisture protection. The high-temperature FluidLoc cable comes standard on all 50 mm probes. Together, these features prevent steam or moisture from entering the probe tip.
Special high-temperature ClickLoc connectors are also standard on the probe and extension cable. Each probe and cable includes connector protectors and a disposable installation tool. This tool keeps connectors free from contamination during setup.
The ClickLoc connector on the probe lead has a removable collar. This collar helps you route the cable through tight clearances inside machinery casings.
The 330876-02-10-01-05 follows a clear suffix structure:
| Suffix | Code | Meaning |
|---|---|---|
| Probe case type | 02 | M14x1.5 thread |
| Total length | 10 | 1.0 metre (3.3 feet) |
| Armor option | 01 | High temp FluidLoc cable with armor |
| Agency approval | 05 | Multiple approvals |
Probe Case Thread: The unit uses M14x1.5 metric threads. Maximum thread engagement length is 21 mm.
Probe Tip Material: The tip is made from Polyphenylene Sulfide (PPS). This material offers excellent heat and chemical resistance.
Probe Case Material: The case uses AISI 304 stainless steel (SST). This provides good corrosion resistance for harsh industrial environments.
Probe Cable: The cable is 75 Ω triaxial with PFA insulation. The FluidLoc design prevents fluid ingress. Total probe length is 1.0 metre as specified.
DC Resistance: From center to coaxial conductor, resistance measures 6.4 ± 0.5 Ω at 1.0 metre length.
Continuous Operating Range: The probe works reliably from -35°C to +200°C (-31°F to +392°F).
Short-Term Tolerance: The device withstands +250°C (+482°F) for less than 24 hours. This covers temporary overload or steam purge events.
Both operating and storage temperatures follow the same ranges.
The overall case diameter is 1.99 inches for both straight exit and side exit versions. The 330876-02-10-01-05 is a straight exit probe with M14x1.5 threads. A locknut with predrilled safety wire holes comes included.
First, clean the mounting hole threads thoroughly before installation. Use the included locknut with safety wire for secure mounting. Next, thread the 330876-02-10-01-05 into the machine casing until the probe tip reaches the correct gap.
Then, connect the probe cable to the extension cable using the ClickLoc connector. Always use the disposable connector protector tool during this step. This prevents contamination from affecting signal quality.
After installation, gap the probe between 0.5 and 1.75 mm (20 to 55 mils) from the target surface. The high-temperature FluidLoc cable resists moisture even in condensing steam environments.
Additionally, avoid bending the cable beyond its minimum radius. Use the removable collar on the ClickLoc connector when routing through tight spaces.
The Agency Approval Option 05 provides multiple certifications for global use. These include ATEX, CSA, and other regional standards for hazardous areas. Always verify local requirements before installation.
