The 330876-01-90-01-05 belongs to the proven 3300 XL series. Bently Nevada engineered this 50 mm proximity probe for extreme turbine environments. It maintains precise measurements without failure, even under intense heat.
Additionally, this probe features both front and rear seals. These seals effectively block moisture from entering the probe tip. For instance, the High Temperature FluidLoc cable comes standard on all 50 mm probes and provides superior moisture resistance. Furthermore, the high-temperature ClickLoc connectors are standard on both the probe and any extension cable.
This 330876-01-90-01-05 model offers a total probe length of 9.0 meters (29.5 feet). The armor option is -00, which means High Temperature FluidLoc Cable. Its agency approval code is -05 for multiple approvals, making it suitable for global installations.
Probe Case Thread: ½-20
Maximum Thread Engagement: 0.750 inch
Overall Case Diameter: 1.99 inches
Case Material: AISI 304 stainless steel (SST)
Tip Material: Polyphenylene Sulfide (PPS)
Meanwhile, the DC resistance from center to coaxial conductor measures 8.9 ± 1.1 Ω. This value applies specifically to the 9.0 meter probe length. The probe cable uses 75 Ω triaxial, PFA insulated FluidLoc construction for reliable signal transmission.
The 3300 XL 50 mm probe delivers 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 applications, it withstands +250°C (+482°F) for less than 24 hours.
Therefore, this probe is ideal for steam turbine DE environments. The straight exit case style features ½-20 English threads and includes a locknut with predrilled safety wire holes. Additionally, the ClickLoc connector on the probe lead has a removable collar. This collar makes routing the cable through tight clearances much easier.
Proper installation maximizes both accuracy and service life. First, confirm the mounting hole has clean, undamaged threads. The maximum length of thread engagement is 0.750 inches. 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 330876-01-90-01-05 probe lead simplifies this task. Always secure the cable away from moving parts or direct heat sources above the rated temperature.

1. What makes this probe suitable for steam turbine DE environments?
The 330876-01-90-01-05 has both front and rear seals. Additionally, the High Temperature FluidLoc cable prevents moisture ingress. These features make it the ideal choice for steam turbine DE applications where moisture and heat are constant concerns.
2. What is the maximum continuous operating temperature?
This 3300 XL 50 mm probe runs continuously at 200°C (392°F) without losing accuracy. It also tolerates intermittent peaks up to 250°C (482°F) for less than 24 hours.
3. What does the -05 agency approval option mean?
The -05 suffix indicates multiple agency approvals. This means the 330876-01-90-01-05 meets various international standards, making it suitable for installations in different regions without additional certification.
4. How do I route the cable through narrow openings?
The ClickLoc connector on this probe has a removable collar. Therefore, you can remove the collar, route the cable through a small opening, and then reattach the collar. This feature saves significant installation time.
5. Does the probe include connector protectors?
Yes, each 330876-01-90-01-05 probe comes with connector protectors installed. Furthermore, a disposable installation tool is included to ensure contamination-free connections during the initial setup.
