The Bently Nevada 330901-00-12-10-11-05 belongs to the 3300 NSv series, which is designed for compact and precise monitoring applications. Specifically, this 3300 NSv Proximity Probe provides accurate non-contact displacement and vibration measurements for smaller rotating machinery. Consequently, it serves as an essential tool for protecting 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 1.2 inches. This extremely short case makes it ideal for installations with very limited clearance. Next, the total probe length is 1.0 metre, which equals 39 inches. Additionally, the connector option includes a miniature coaxial ClickLoc connector with a connector protector and FluidLoc cable. The FluidLoc cable provides enhanced resistance to fluid ingress, making it suitable for wet or oily environments. Furthermore, this unit carries multiple agency approvals (Option 05), ensuring compliance for use in various regulated regions.
Moreover, 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 offer excellent corrosion resistance and mechanical durability. Meanwhile, the 75 Ω coaxial cable features FEP insulation for stable signal transmission over the 1.0-metre length.
The probe cable uses a 75 Ω coaxial design with fluoroethylene propylene (FEP) insulation. This model comes with a 1.0-metre FluidLoc cable. Additionally, the DC resistance from the center conductor to the outer conductor (RPROBE) measures 4.2 ± 0.5 ohms. This low resistance ensures consistent and accurate signal transfer.
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.
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).
First, clean the target surface and the mounting hole thoroughly before installing the Bently Nevada 330901-00-12-10-11-05. 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.
Next, route the FluidLoc FEP insulated coaxial cable with care. Specifically, maintain a minimum bend radius of (blue)25.4 mm(/blue) at all times. The FluidLoc cable offers superior protection against moisture and oil ingress, but sharp bends can still damage the internal conductor. Additionally, use the ClickLoc connector with its protector to attach the extension cable firmly. Remember to tighten it finger tight only, as excessive torque can damage the connector mechanism.
Moreover, this probe's extremely short case length of 1.2 inches makes it one of the most compact options in the 3300 NSv series. Its 1.0-metre cable provides sufficient reach for most small machinery installations while minimizing cable clutter. Meanwhile, the lightweight construction reduces mechanical stress on mounting brackets.
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.

Q1: What is the thread size of the Bently Nevada 330901-00-12-10-11-05?
A1: This probe features a 1/4-28 UNF thread. The maximum thread engagement length is 0.375 inches.
Q2: What makes FluidLoc cable different from standard cable?
A2: FluidLoc cable provides enhanced resistance to moisture and oil ingress, making it ideal for wet or harsh industrial environments where standard cables might fail.
Q3: What is the total cable length for this model?
A3: This model includes a 1.0-metre (39 inches) coaxial FEP FluidLoc cable. Other lengths (0.5, 5, or 7 metres) are available as different options.
Q4: What do the multiple agency approvals include?
A4: Option 05 indicates this probe carries multiple agency certifications (such as CSA, ATEX, or IECEx), making it suitable for installations in regions with strict regulatory requirements.
Q5: How tight should I fasten the connector?
A5: 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.
