Bently Nevada 330709-000-060-50-01-05 3300 XL 11 mm Proximity Probe

Product Introduction

The Bently Nevada 330709-000-060-50-01-05 is a 3300 XL 11 mm proximity probe designed for precise measurement of radial vibration and axial position in rotating machinery. Manufactured in the U.S.A., this probe features an M16 x 1.5 thread, a 5.0-meter cable, and a miniature coaxial ClickLoc connector with connector protector. It is part of the 3300 XL series, known for enhanced linearity and improved accuracy. The model number 330709-000-060-50-01-05 indicates specific options: unthreaded length 0 mm, overall case length 60 mm, total length 5.0 meters, and multiple agency approvals.

Parameter Analysis

The 5.0-meter probe length is designed for use with the 5.0-meter Proximitor Sensor only, ensuring proper impedance matching. The DC resistance of 7.2 ± 0.8 ohms is critical for accurate signal transmission. The probe tip material (PPS) offers excellent durability and chemical resistance. The stainless steel case provides robust mechanical protection. The temperature range allows operation in harsh environments, but note that exposure below -34°C may affect the pressure seal.

Application Scenarios

This proximity probe is ideal for monitoring vibration and position in turbines, compressors, pumps, and other rotating machinery. It is commonly used in critical applications such as steam turbines, gas turbines, centrifugal compressors, and large pumps where reliable condition monitoring is essential. The 3300 XL 11 mm probe is suitable for shaft vibration and thrust position measurements.

Installation Guide

Install the probe with the M16 x 1.5 thread into a suitable mounting hole. Ensure the thread engagement does not exceed 24 mm. Apply the recommended torque of 21.1 N•m (187 in•lb) for the probe case. Connect the miniature coaxial ClickLoc connector to the extension cable or Proximitor, tightening finger tight plus a maximum of 0.565 N•m (5 in•lb). Maintain a minimum bend radius of 25.4 mm for the cable. Verify the target size: minimum flat surface diameter 30.5 mm, minimum shaft diameter 152 mm.

Compatibility

This probe is compatible with Bently Nevada 3300 XL series systems, specifically designed for use with the 5.0-meter Proximitor Sensor. It can be used with 3300/3500 monitoring systems when paired with appropriate extension cables and Proximitors. The connector type is miniature coaxial ClickLoc, which is standard for Bently Nevada.

Maintenance Advice

Regularly inspect the probe tip and cable for damage. Clean the probe tip with a soft cloth if contaminated. Avoid exposing the probe to temperatures below -34°C to prevent pressure seal failure. Check the connector tightness periodically. Ensure the cable is not bent beyond the minimum bend radius. For accurate readings, verify the gap voltage and target condition.

Procurement Advice

When ordering the Bently Nevada 330709-000-060-50-01-05, confirm the exact model number to ensure correct options. Verify the probe length (5.0 m) matches your Proximitor sensor. Consider purchasing a spare probe for critical machinery. Check agency approval requirements for your region. For technical support, contact TenBN, an authorized channel for Bently Nevada products.
