Bently Nevada 330709-000-070-50-11-05 3300 XL 11 mm Proximity Probe

产品 Introduction

The Bently Nevada 330709-000-070-50-11-05 is a 3300 XL 11 mm Proximity Probe, designed for precise measurement of shaft vibration and position in critical rotating machinery. This model features a 5.0 meter total length, M16 x 1.5 thread, and a miniature coaxial ClickLoc connector with FluidLoc cable, ensuring robust and reliable performance in demanding industrial environments.

Technical Parameters

• Probe Length: 5.0 meters (16.4 feet)
• Probe DC Resistance: 7.2 ± 0.8 ohms
• Probe Tip Material: Polyphenylene sulfide (PPS)
• Probe Case Material: AISI 304 stainless steel
• Probe Cable: 75 Ω triaxial, FEP insulated
• Operating Temperature: -52°C to +177°C (-62°F to +351°F)
• Thread: M16 x 1.5, max engagement 24 mm
• Connector: Miniature coaxial ClickLoc with connector protector

参数 Analysis

The 5.0 meter probe length is specifically designed for use with the 5.0 meter Proximitor Sensor, ensuring optimal signal integrity. The DC resistance of 7.2 ± 0.8 ohms is critical for accurate eddy-current sensing. The PPS tip and stainless steel case provide durability and corrosion resistance. The operating temperature range of -52°C to +177°C allows use in extreme conditions, though exposure below -34°C may affect the pressure seal.

应用 Scenarios

This probe is ideal for monitoring vibration and position in turbines, compressors, pumps, and other rotating machinery. It is commonly used in oil & gas, power generation, and manufacturing industries where machine health monitoring is essential for predictive maintenance and preventing unplanned downtime.

Installation Guide

Install the probe with the recommended torque of 21.1 N•m (187 in•lb) and maximum 63.3 N•m (560 in•lb). Ensure the target surface is flat with a minimum diameter of 30.5 mm (1.2 in) and shaft diameter of 152 mm (6.0 in) to avoid cross-talk. Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. The connector should be finger tight, with a maximum torque of 0.565 N•m (5 in•lb).

Compatibility

This probe is part of the 3300 XL series and is compatible with Bently Nevada 3300 XL Proximitors and monitoring systems. It is designed for use with the 5.0 meter Proximitor Sensor only.

Maintenance Advice

Regularly inspect the probe tip and cable for damage. Clean the probe tip with a soft cloth and approved solvent. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. Check connector tightness periodically.

Procurement Advice

When ordering, verify the model number 330709-000-070-50-11-05 to ensure correct specifications. Consider purchasing spare probes for critical machinery to minimize downtime. Ensure compatibility with your existing Proximitor and monitoring system.
