Bently Nevada 330901-00-16-05-02-05 NSv Probe

Bently Nevada 330901-00-16-05-02-05 3300 NSv Proximity Probe

Product Introduction

The Bently Nevada 330901-00-16-05-02-05 belongs to the 3300 NSv series, which is recognized for its compact and lightweight design. Specifically, this 3300 NSv Proximity Probe delivers accurate non-contact displacement and vibration measurements for smaller rotating equipment. Consequently, it serves as a reliable monitoring solution for pumps, motors, and light-duty turbines.

First, this model features a 1/4-28 UNF thread case without armor. Its unthreaded length is 0 inches, while the overall case length is only 1.6 inches. This short case makes it exceptionally suitable for installations with severe space constraints. Next, the total probe length is 0.5 metre, which equals 20 inches. Additionally, the connector option includes a miniature coaxial ClickLoc connector with standard cable. Notably, this unit carries multiple agency approvals (Option 05), making it compliant for use in various regulated regions.

Furthermore, the probe tip uses polyphenylene sulfide (PPS) material. The probe case, in turn, is constructed from AISI 304 stainless steel (SST). For instance, these materials provide excellent corrosion resistance and mechanical durability. Meanwhile, the 75 Ω coaxial cable features FEP insulation for stable signal transmission over the short cable run.

Technical Specifications

Electrical and Cable Parameters

The probe cable uses a 75 Ω coaxial design with fluoroethylene propylene (FEP) insulation. This model comes in a 0.5-metre total length. Additionally, the DC resistance from the center conductor to the outer conductor (RPROBE) measures 4.0 ± 0.5 ohms. This low resistance ensures consistent and accurate signal transfer.

Mechanical and Environmental Ratings

The operating temperature range spans from -52°C to +177°C (-62°F to +351°F). Similarly, the storage temperature range is identical. However, exposing this 3300 NSv Proximity Probe to temperatures below -34°C (-30°F) for a sustained period may cause premature pressure seal failure. Therefore, you should avoid prolonged low-temperature exposure whenever possible.

Furthermore, the probe seals differential pressure between the tip and the case using a Viton O-ring. Bently Nevada does not pressure-test these probes prior to shipment. For custom pressure testing, please contact their design department directly.

Torque and Thread Engagement

For the 1/4-28 probe case thread, the maximum length of thread engagement is 0.375 inches. The maximum rated torque for this case reaches (red)7.3 N•m (65 in•lb)(/red). However, the recommended installation torque is (red)5.1 N•m (45 in•lb)(/red). Following this recommended value prevents thread damage and ensures reliable mounting.

The connector-to-connector torque should be finger tight only. Its maximum torque is (blue)0.565 N•m (5 in•lb)(/blue). Finally, the minimum bend radius for the cable is (blue)25.4 mm (1.0 inch)(/blue).

Installation Guidelines

Mounting and Positioning

First, clean the target surface and the mounting hole thoroughly before installing the Bently Nevada 330901-00-16-05-02-05. Then, thread the probe carefully using the 1/4-28 UNF thread. For instance, apply the recommended torque of (red)5.1 N•m(/red) to secure it properly. Over-tightening may strip the fine threads or deform the probe case.

Cable Routing and Bend Radius

Next, route the FEP insulated coaxial cable with care. Specifically, maintain a minimum bend radius of (blue)25.4 mm(/blue) at all times. Sharp bends can degrade signal quality or break the internal conductor. Additionally, use the ClickLoc connector to attach the extension cable firmly. Remember to tighten it finger tight only, as excessive torque can damage the connector mechanism.

Compact Design Advantages

Moreover, this probe's extremely short case length of 1.6 inches makes it ideal for tight machinery clearances. Its 0.5-metre cable reduces clutter and simplifies routing in confined panels. Meanwhile, the lightweight construction (as low as 14 g) minimizes mechanical stress on mounting brackets.

Environmental Precautions

Furthermore, avoid operating this 3300 NSv Proximity Probe below -34°C for extended periods. This precaution preserves the pressure seal's integrity over time. Also, inspect the Viton O-ring for any visible damage before installation. A compromised seal may lead to fluid ingress and measurement inaccuracies.

Q2: What is the total cable length for this model?
A2: This model includes a 0.5-metre (20 inches) coaxial FEP cable. Other lengths (1, 5, or 7 metres) are available as different options.

Q3: What do the multiple agency approvals mean?
A3: Option 05 indicates this probe carries multiple agency certifications, making it suitable for installations in regions with strict regulatory requirements.

Q4: How tight should I fasten the connector?
A4: Tighten the ClickLoc connector finger tight only. The maximum torque for the connector is 0.565 N•m (5 in•lb). Over-tightening can break the connector.

Q5: What is the minimum bend radius for the probe cable?
A5: The minimum bend radius is 25.4 mm (1.0 inch). Bending it more sharply may damage the insulation or internal conductor, affecting signal quality.
