Bently Nevada 330876-01-90-00-RU Probe 50mm

Bently Nevada 330876-01-90-00-RU 3300 XL 50mm Proximity Probe

Product Introduction

The 330876-01-90-00-RU belongs to the trusted 3300 XL series. Bently Nevada designed this 50 mm proximity probe for the harshest turbine environments. It maintains accuracy without failure, even at extreme temperatures.

Additionally, this probe includes both front and rear seals. These seals prevent moisture from entering the probe tip. For instance, the High Temperature FluidLoc cable (standard on all 50 mm probes) resists moisture ingress effectively. Furthermore, the special high-temperature ClickLoc connectors come standard on the probe and extension cable.

Technical Specifications

This 330876-01-90-00-RU 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 -RU for country-specific use.

• 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.

Environmental and Mechanical Ratings

The 3300 XL 50 mm probe operates reliably in extreme 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 suits steam turbine DE environments perfectly. 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 facilitates routing the cable through tight clearances.

Installation Guidelines

Proper installation ensures maximum accuracy and longevity. First, ensure the mounting hole has clean threads. The maximum length of thread engagement is 0.750 inches. Do not exceed this value.

Next, use the disposable connector protector installation tool. This tool keeps connectors free from contamination during installation. Meanwhile, each probe and cable comes with connector protectors. These protectors prevent dirt and moisture from entering the ClickLoc connectors.

Finally, route the cable carefully through tight clearances. The removable collar on the 330876-01-90-00-RU probe lead makes this task easier. Always secure the cable away from moving parts or extreme heat sources.
