Bently Nevada 330876-02-10-01-00 - 50mm Probe

Bently Nevada 330876-02-10-01-00 3300 XL 50mm Proximity Probe

Product Introduction

The 330876-02-10-01-00 belongs to the proven 3300 XL series. Bently Nevada designed this 50 mm proximity probe for the harshest turbine environments. It delivers accurate measurements continuously, even under extreme heat and mechanical stress.

Additionally, this probe includes 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, this version adds armor option -01, which means the cable includes extra mechanical protection for demanding installations.

Technical Specifications

This 330876-02-10-01-00 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 -01 for High Temperature FluidLoc Cable with Armor. 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 resistance value applies specifically to the 1.0 meter probe length. The probe cable uses 75 Ω triaxial, PFA insulated FluidLoc construction with an additional armor layer for enhanced durability.

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.

Armored Cable Advantage

The armor option on the 330876-02-10-01-00 provides extra protection. This armored cable resists cutting, abrasion, and impact damage. For instance, installations with sharp edges or frequent vibration benefit greatly from this feature.

Moreover, the armor does not compromise flexibility. You can still route the cable through moderate bends and tight spaces. The removable ClickLoc collar remains fully functional with the armored cable version.

Installation Guidelines

Proper installation ensures maximum performance and service life. 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 armored cable carefully. Although the armor provides excellent protection, avoid sharp bends or crushing forces. Secure the cable away from moving parts or direct heat sources above the rated temperature.

Frequently Asked Questions (FAQ)

1. What is the difference between -00 and -01 armor options?

The -00 option is standard High Temperature FluidLoc cable without armor. The -01 option on the 330876-02-10-01-00 adds a protective armor layer over the cable. This armor provides extra resistance against cutting, abrasion, and mechanical impact.

2. What thread type does this probe use?

The 330876-02-10-01-00 uses M14x1.5 metric threads. This is the metric thread version. Always check your mounting hole specifications before ordering to ensure compatibility.

3. Does the armored cable affect the probe's temperature rating?

No, the armored cable maintains the same temperature rating. The 3300 XL 50 mm probe with armor still operates continuously at 200°C (392°F) and withstands intermittent peaks up to 250°C (482°F).

4. 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. The armored version retains all these moisture protection features.

5. What is the DC resistance for this 1.0 meter probe?

The DC resistance from center to coaxial conductor is 6.4 ± 0.5 Ω for the 1.0 meter length. The armored cable option does not change this electrical specification.
