Bently Nevada 330909-00-60-10-02-00 3300 NSv Probe

Product Introduction

The Bently Nevada 330909-00-60-10-02-00 is a precision 3300 NSv series eddy-current proximity probe. It performs non-contact measurement of shaft vibration, position, and speed in rotating machinery. This sensor outputs a linear voltage proportional to the gap between the probe tip and the target surface. Therefore, it serves as an essential component for predictive maintenance and machine protection systems.

This model offers a robust and versatile design. It features a Polyphenylene sulfide (PPS) probe tip and an AISI 304 stainless steel case for superior durability. The probe cable uses a 75 Ω coaxial type with fluoroethylene propylene (FEP) insulation to maintain signal integrity. Additionally, the 3/8-24 UNF thread enables secure installation in various mounting configurations. This particular configuration includes a 1.0 metre total length and a Miniature coaxial ClickLoc connector without a connector protector. Furthermore, it does not require agency approvals for standard applications.

Technical Specifications

This section details the core technical parameters of the 3300 NSv Proximity Probe.

Electrical Properties

The Bently Nevada 330909-00-60-10-02-00 demonstrates consistent electrical performance. The DC resistance from the center conductor to the outer conductor (RPROBE) measures 4.2 ± 0.5 ohms for the 1.0 metre length. This stable resistance value supports accurate and repeatable measurements. Moreover, the probe cable utilizes a 75 Ω coaxial design with FEP insulation to minimize signal degradation and electromagnetic interference.

Mechanical Dimensions

The mechanical configuration of the 3300 NSv probe offers flexibility for various installations. The unthreaded length option is 0.0 inches, while the overall case length is 6.0 inches. For the 3/8-24 UNF thread option, the maximum length of thread engagement is 0.563 inches. The total probe length is 1.0 metre (39 inches) . Additionally, the probe weight ranges approximately from 14 to 150 grams (0.5 to 5.3 oz) , making it suitable for a wide range of applications.

Material Composition

Durable materials ensure long-term reliability. The probe tip is constructed from Polyphenylene sulfide (PPS) , a high-performance engineering thermoplastic. The probe case is manufactured from AISI 304 stainless steel (SST) , offering excellent corrosion resistance. The cable insulation uses fluoroethylene propylene (FEP) . Additionally, a Viton O-ring provides the sealing function between the tip and the case.

Environmental and Mechanical Parameters

The Bently Nevada 330909-00-60-10-02-00 performs reliably under demanding conditions.

Temperature Ranges

The probe operates and stores within a temperature range of -52°C to +177°C (-62°F to +351°F) . However, exposing the probe to temperatures below -34°C (-30°F) for a sustained period may cause premature failure of the pressure seal. The device also meets multiple temperature classifications for explosive atmospheres (EPL Ga, Gc, Dc) with varying ambient temperature limits.

Pressure and Sealing

The 3300 NSv probe seals differential pressure between the tip and case effectively. A Viton O-ring accomplishes this sealing function. Please note that these probes do not undergo pressure testing before shipment. Meanwhile, the probe DC resistance remains a critical parameter for system calibration.

Installation Guidelines

Installing the Bently Nevada 330909-00-60-10-02-00 requires careful attention to several key factors.

First, clean the target surface thoroughly to remove any debris or contaminants. The standard target material for 3300 NSv probes is typically AISI 4140 steel. Next, check the thread engagement precision carefully. For the 3/8-24 UNF thread, the maximum engagement length is 0.563 inches. Specifically, apply the recommended torque of 11.3 N•m (100 in•lb) to avoid damaging the probe or the mounting hardware. For applications involving only the first three threads, use the lower torque value of 7.5 N•m (66 in•lb) .

Then, route the cable with caution. Maintain a minimum bend radius of 25.4 mm (1.0 inch) to prevent damage to the internal conductors. When connecting the Miniature coaxial ClickLoc connector, tighten it finger-tight only. Never exceed the maximum torque of 0.565 N•m (5 in•lb) . Finally, verify the total probe length of 1.0 metre suits your specific application requirements.
