Bently Nevada 330901-08-21-10-02-00 Probe

Bently Nevada 330901-08-21-10-02-00 3300 NSv Proximity Probe

The 330901-08-21-10-02-00 model is a genuine Bently Nevada 3300 NSv Proximity Probe. It belongs to the 3300 NSv series, which is specifically engineered for machinery monitoring in areas with tight installation constraints. This probe provides non-contact measurement of shaft vibration and position.

Product Introduction

This 330901-08-21-10-02-00 probe is a compact eddy-current sensor. It operates as part of the 3300 XL NSv Transducer System. The system delivers a standard scale factor of 7.87 V/mm (200 mV/mil), ensuring compatibility with common monitoring systems. Furthermore, the NSv series offers enhanced side-view characteristics. This feature significantly reduces cross-talk in high-density mounting scenarios where standard 8mm probes may not fit.

Technical Specifications

The probe features a 1/4-28 UNF mounting thread and is supplied without armor. Its unthreaded length is 0.8 inches (08), and the overall case length is 2.1 inches (21). Moreover, the total cable length is 1.0 meter (10). The cable is a 75 Ω coaxial type with FEP insulation. It terminates in a miniature coaxial ClickLoc connector (02). This specific model does not require agency approval (00).

The probe case is constructed from AISI 304 stainless steel. The probe tip is made from Polyphenylene Sulfide (PPS). For a 1.0-meter probe, the DC resistance from the center conductor to the outer conductor is 4.2 Ω ± 0.5 Ω.

Mechanical & Environmental Parameters

The operating and storage temperature range for this probe is -52°C to +177°C (-62°F to +351°F). However, sustained exposure to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Notably, Bently Nevada does not pressure test probes prior to shipment.

The maximum recommended torque for the 1/4-28 probe case is 5.1 N•m (45 in•lb). Additionally, the maximum thread engagement length for this thread type is 0.375 inches (9.5 mm). The probe weight ranges from approximately 14 to 150 grams depending on the configuration.

Installation Guide

First, prepare the 1/4-28 UNF threaded mounting hole and ensure it is clean. Next, carefully insert the 330901-08-21-10-02-00 probe into the hole. Then, hand-tighten the probe to avoid cross-threading. Finally, use a torque wrench to tighten the probe case to the recommended 5.1 N•m (45 in•lb). It is critical not to exceed the maximum rated torque of 7.3 N•m (65 in•lb).

Furthermore, route the 1.0-meter cable carefully. Avoid sharp bends that could damage the FEP insulation. The miniature coaxial ClickLoc connector provides a secure, locking connection. For optimal signal integrity, keep the connector clean and dry during installation.
