Bently Nevada 330708-00-10-50-01-00 11mm Probe 5.0m

Bently Nevada 330708-00-10-50-01-00 3300 XL 11mm Proximity Probe

Product Introduction

The Bently Nevada 330708-00-10-50-01-00 is a precision-engineered 3300 XL 11 mm proximity probe designed for non-contacting vibration and position measurement. This probe features a 5.0-meter (16.4 feet) total length with standard cable and a miniature coaxial ClickLoc connector. Specifically, the probe tip uses Polyphenylene sulfide (PPS) material, while the case is constructed from AISI 304 stainless steel for superior corrosion resistance. Furthermore, it offers a wide operating temperature range from -51°C to +177°C (-60°F to +351°F). Therefore, it is an ideal choice for critical turbomachinery applications such as compressors, turbines, and pumps. Additionally, the 5/8-18 UNF thread ensures compatibility with standard mounting hardware. Meanwhile, the patented TipLoc and CableLoc designs provide enhanced durability and pull strength.

Temperature and Environmental Specifications

Understanding the operational limits is crucial for reliable long-term performance.

Temperature Range:

• Operating and Storage Temperature: -51°C to +177°C (-60°F to +351°F).

• Important Note: Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Therefore, consider this limitation when planning installations in cold environments.

Pressure Seal:
The 3300 XL probes are designed to seal differential pressure between the probe tip and case. The probe sealing material consists of a Viton® O-ring. For instance, this seal prevents process fluids from entering the probe interior. However, probes are not pressure tested prior to shipment. Consequently, contact our custom design department if you require a test of the pressure seal for your specific application.

Mechanical Durability Features

The 3300 XL 11 mm probe incorporates several improvements over previous designs.

Patented TipLoc Molding:
The TipLoc molding method provides a more robust bond between the probe tip and the probe body. As a result, this enhances the structural integrity of the probe under vibration and thermal cycling.

Patented CableLoc Design:
The probe's cable incorporates a patented CableLoc design. Specifically, this provides 330 N (75 lbf) pull strength to more securely attach the probe cable and probe tip. Therefore, it reduces the risk of cable detachment during installation or operation.

Thread Options:
This model features the 5/8-18 UNF thread. Meanwhile, other thread options like M16x1.5 and M14x1.5 are available for different mounting requirements. For instance, M16x1.5 has a maximum thread engagement of 24 mm, while M14x1.5 has 21 mm.

Installation and Connectivity

Proper installation ensures optimal performance of the Bently Nevada system.

Mounting Guidelines:

• Apply the recommended torque of 15.2 N•m (133 in•lb) when installing the probe. Do not exceed the maximum rated torque of 45.2 N•m (400 in•lb).

• For the connector, finger-tight is recommended, with a maximum of 0.565 N•m (5 in•lb).

• Ensure the minimum bend radius of 25.4 mm (1.0 inch) is maintained to prevent cable damage.

Compatibility:
This probe accepts one non-contacting 3300 XL 11 mm Proximity Probe and Extension Cable. For optimal performance, use genuine Bently Nevada extension cables and Proximitor sensors.

System Performance:
Unless otherwise noted, specifications apply to a system consisting of a 3300 XL 11 mm Proximitor Sensor, extension cable, and probe between +18˚C and +27˚C (+64˚F to +80˚F) at a maximum altitude of 2000 meters. System accuracy applies to calibration against an AISI 4140 steel target.
