Bently Nevada 330707-20-30-10-01-05 Proximity Probe

Product Introduction

This Bently Nevada 330707-20-30-10-01-05 is a premium 3300 XL series sensor. It is designed for non-contact vibration and displacement monitoring of rotating machinery. The probe incorporates advanced eddy current technology for exceptional linearity and stability. Specifically, the Bently Nevada 330707-20-30-10-01-05 comes with an unthreaded length of 2.0 inches and a 3.0-inch overall case length. Meanwhile, its total length is precisely 1.0 metre (3.3 feet). Furthermore, it uses the miniature coaxial ClickLoc connector with a connector protector for enhanced durability. In addition, this model carries multiple agency approvals (Option 05) for global compliance.

Technical Specifications

The Bently Nevada 330707-20-30-10-01-05 offers precise specifications for critical applications. Its robust design ensures reliable data under demanding conditions. For instance, the probe tip uses Polyphenylene sulfide (PPS) for excellent chemical resistance. Meanwhile, the probe case is constructed from AISI 304 stainless steel (SST) for superior durability. Moreover, the cable features 75 Ω triaxial, fluoroethylene propylene (FEP) insulation. Consequently, this configuration delivers consistent signal integrity over extended periods. Additionally, the DC resistance from the center conductor to the outer conductor measures 5.9 ± 0.5 ohms. Therefore, you can expect stable and repeatable performance from this 3300 XL probe.

Mechanical & Environmental Parameters

This 3300 XL probe operates effectively in harsh industrial settings. Its construction materials are chosen for longevity and consistent performance. For example, the operating and storage temperature range spans from -51°C to +177°C (-60°F to +351°F). However, exposing the probe to temperatures below -34°C (30°F) may cause premature failure of the pressure seal. Therefore, careful attention to operating conditions is strongly advised. Additionally, the pressure seal uses a Viton O-ring to maintain differential pressure integrity. Meanwhile, the minimum bend radius is 25.4 mm (1.0 in) regardless of whether armor is present. Consequently, this flexibility simplifies cable routing in confined spaces. Furthermore, the recommended case torque is 15.2 N•m (133 in•lb), while the maximum rated torque is 45.2 N•m (400 in•lb). Similarly, the connector should be finger-tightened only, with an absolute maximum of 0.565 N•m (5 in•lb).

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

• Pressure Seal: The probe uses a Viton O-ring to seal differential pressure.

• Minimum Bend Radius: 25.4 mm (1.0 in) with or without armor.

• Case Torque (Maximum): 45.2 N•m (400 in•lb).

• Case Torque (Recommended): 15.2 N•m (133 in•lb).

• Connector Torque (Maximum): 0.565 N•m (5 in•lb).

• Connector Torque (Recommended): Finger tight.

Installation & Mounting Guide

Proper installation of the Bently Nevada 330707-20-30-10-01-05 is essential for accurate measurements. Therefore, please follow these guidelines carefully. First, ensure the mounting surface is clean and free of debris. Next, thread the probe into the mounting hole using the 5/8-18 UNF threads. Remember that the maximum length of thread engagement is 0.938 inches. Consequently, avoid over-torquing the probe case. The recommended torque is 15.2 N•m. After mounting, connect the ClickLoc connector. Finger-tighten the connector initially. The maximum torque for this connection is only 0.565 N•m. Finally, route the probe cable with a minimum bend radius of 25.4 mm. In addition, always verify that the cable is not sharply kinked or pinched during installation. Also, ensure that the probe tip remains free from contamination before final positioning. Moreover, consider using a torque wrench for precise tightening to avoid damaging the threads. Following these steps will maximize the service life of your 3300 XL probe.
