Bently Nevada 330901-22-90-05-01-00 NSv Probe

Bently Nevada 330901-22-90-05-01-00 3300 NSv Proximity Probe

Product Introduction

The Bently Nevada 330901-22-90-05-01-00 belongs to the 3300 NSv series, which is known for its compact form factor. Specifically, this 3300 NSv Proximity Probe delivers precise displacement and vibration measurements for smaller rotating equipment. Consequently, it plays an important role in protecting pumps, motors, and light-duty turbines.

First, this model features a 1/4-28 UNF thread case without armor. Its unthreaded length is 2.2 inches, while the overall case length measures 9.0 inches. Next, the total probe length is only 0.5 metre, which equals 20 inches. This shorter length makes it ideal for installations with limited space. Additionally, the connector option includes a miniature coaxial ClickLoc connector with a protector and standard cable. This unit does not require agency approvals (Option 00).

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 resist corrosion and provide durability in industrial environments. Meanwhile, the 75 Ω coaxial cable features FEP insulation for reliable signal transmission.

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 value ensures accurate signal transfer over the short cable run.

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.

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 before 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 secure 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, with or without armor, is (blue)25.4 mm (1.0 inch)(/blue).

Installation Guidelines

Mounting and Positioning

First, clean the target surface and the mounting hole before installing the Bently Nevada 330901-22-90-05-01-00. 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 damage 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.

Space-Saving Advantages

Moreover, this 0.5-metre probe is particularly useful in confined installations. Its short cable length reduces clutter and simplifies cable management. Meanwhile, the compact 1/4-28 thread fits smaller mounting holes commonly found on light-duty machinery.

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 errors.

Frequently Asked Questions (FAQ)

Q1: What is the thread size of the Bently Nevada 330901-22-90-05-01-00?
A1: This probe features a 1/4-28 UNF thread. The maximum thread engagement length is 0.375 inches.

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: Can I use this probe with standard extension cables?
A3: Yes, the 3300 NSv series works with compatible extension cables. However, always verify the total system length does not exceed the Proximitor Sensor's specifications.

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.
