Bently Nevada 330707-00-26-10-11-05 Proximity Probe

Bently Nevada 330707-00-26-10-11-05 3300 XL 11 mm Proximity Probe

Product Introduction

The Bently Nevada 330707-00-26-10-11-05 belongs to the trusted 3300 XL series. Specifically, this 3300 XL 11 mm Proximity Probe provides precise shaft displacement and vibration monitoring. Consequently, it plays a vital role in protecting critical rotating machinery.

First, this model features a 5/8-18 UNF thread case without armor. Its unthreaded length is 0 inches, while the overall case length measures 2.6 inches. Next, the total probe length reaches 1.0 metre, which equals 3.3 feet. Additionally, the connector option includes a miniature coaxial ClickLoc connector with a protector. This connector also comes with FluidLoc cable for enhanced durability. Furthermore, this unit holds multiple agency approvals (Option 05).

Therefore, the Bently Nevada 330707-00-26-10-11-05 ensures reliable performance in harsh environments. Meanwhile, its 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 mechanical stress effectively.

Technical Specifications

Electrical and Cable Parameters

The probe cable uses a 75 Ω triaxial design. Moreover, it features fluoroethylene propylene (FEP) insulation. This probe comes in a 1.0-metre total length. Additionally, the DC resistance from the center conductor to the outer conductor (RPROBE) measures 5.9 ± 0.5 ohms. This value ensures accurate signal transmission.

Mechanical and Environmental Ratings

The operating and storage temperature range spans from -51°C to +177°C (-60°F to +351°F). However, exposing this 3300 XL 11 mm Probe to temperatures below -34°C (30°F) may cause premature pressure seal failure. Therefore, you should avoid such conditions. Furthermore, the probe seals differential pressure between the tip and the case using a Viton O-ring. Please note that Bently Nevada does not pressure-test these probes before shipment. For custom pressure testing, contact their design department.

Torque and Thread Engagement

For the 5/8-18 probe case thread, the maximum length of thread engagement is 0.938 inches. The maximum rated torque for this case reaches 45.2 N•m (400 in•lb). However, the recommended installation torque is (red)15.2 N•m (133 in•lb)(/red). Following this recommendation prevents mechanical damage. Meanwhile, the connector-to-connector torque should be finger tight. Its maximum torque is only 0.565 N•m (5 in•lb). Finally, the minimum bend radius for the cable, with or without SST armor, is (blue)25.4 mm (1.0 inch)(/blue).

Installation Guidelines

Mounting and Positioning

First, ensure the target surface is clean and smooth before installing the Bently Nevada 330707-00-26-10-11-05. Then, thread the probe carefully into the mounting hole using the 5/8-18 UNF thread. For instance, apply the recommended torque of (red)15.2 N•m(/red) to secure it firmly. Over-tightening may strip the threads or damage the probe case.

Cable Routing and Bend Radius

Next, route the FEP insulated triaxial 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 conductors. 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.

Environmental Precautions

Furthermore, avoid operating this 3300 XL 11 mm Proximity Probe in temperatures below -34°C. This precaution preserves the pressure seal’s integrity. Also, check the Viton O-ring for any visible damage before installation. A compromised seal reduces the probe's pressure rating.

Frequently Asked Questions (FAQ)

Q1: What is the exact thread size of the Bently Nevada 330707-00-26-10-11-05?
A1: This probe features a 5/8-18 UNF thread. The maximum thread engagement length is 0.938 inches.

Q2: Can I use this 3300 XL 11 mm Probe in high-pressure applications?
A2: Yes, it seals differential pressure with a Viton O-ring. However, Bently Nevada does not pressure-test each unit. Contact them if you require specific pressure testing.

Q3: What cable length does model 330707-00-26-10-11-05 come with?
A3: This model includes a 1.0-metre (3.3 feet) triaxial FEP cable. Other cable lengths (5 or 9 metres) are available as different options.

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

Q5: What is the minimum bend radius for the probe cable?
A5: The minimum bend radius is 25.4 mm (1.0 inch), whether the cable has SST armor or not. Bending it more sharply may damage the insulation or conductors.
