Proximity Probe | Bently Nevada 330708-00-10-90-11-00

Product Introduction

The Bently Nevada 330708-00-10-90-11-00 provides reliable, non-contact displacement measurement for your most valuable rotating assets. It belongs to the renowned 3300 XL series, which plays a vital role in vibration monitoring for turbines, compressors, and pumps. Its robust construction guarantees accurate data even under harsh industrial conditions.

Detailed Technical Specifications

This model features a comprehensive set of engineering attributes that define its performance. First, the probe tip utilizes Polyphenylene sulfide (PPS), which offers excellent resistance to wear and chemical attack. Additionally, the probe case uses AISI 304 stainless steel (SST) to deliver outstanding structural integrity and corrosion protection.

The overall case length of this particular variant measures 1.0 inch, as indicated by the "10" option in the part number. This shorter case length suits applications with limited mounting depth requirements. Furthermore, the electrical characteristics directly impact signal quality. The probe cable employs a 75 Ω triaxial design with fluoroethylene propylene (FEP) insulation. This 9.0-metre probe exhibits a specific DC resistance between the center and outer conductors, measuring 8.5 ± 1.1 ohms. This precise resistance value ensures accurate and consistent output from the Bently Nevada 330708-00-10-90-11-00.

The assembly incorporates the Miniature coaxial ClickLoc connector with connector protector, which provides a secure and positive lock for reliable connections in high-vibration environments. Moreover, this model features FluidLoc cable, a specialized cable type that offers enhanced resistance to fluid ingress and contamination. This makes the 3300 XL 11 mm probe particularly suitable for environments where oil or other process fluids may be present.

Mechanical and Environmental Parameters

The Bently Nevada 3300 XL probe operates effectively in demanding settings. It supports an operating temperature range from -51°C to +177°C. However, prolonged exposure below -34°C can stress the pressure seal. For installation, the probe features a 5/8-18 UNF thread with a maximum thread engagement of 0.938 inches.

Moreover, specific torque values guarantee proper installation. We strongly recommend tightening the probe case to 15.2 N•m (133 in•lb) , while the absolute maximum rating reaches 45.2 N•m (400 in•lb). For the ClickLoc connector, finger-tightness suffices to avoid damage, with a maximum torque of just 0.565 N•m (5 in•lb).

The probe cable maintains a minimum bend radius of 25.4 mm (1.0 in) , which plays a crucial role in preserving cable integrity during routing. This specification applies equally to both armored and non-armored versions of the 3300 XL 11 mm probe. These parameters allow the Bently Nevada 330708-00-10-90-11-00 to perform within its design limits across diverse industrial applications.

Installation Guidelines

Proper installation of the Bently Nevada 330708 ensures optimal performance. First, clean the mounting surface and remove any debris from the threads. Then, thread the probe into the housing and confirm that the engagement length does not exceed the maximum specified limit of 0.938 inches.

Next, tighten the probe case to the recommended torque of 15.2 N•m. Using a torque wrench prevents over-tightening, which could otherwise damage the probe. Finally, connect the ClickLoc connector by pushing it in until you hear a click. Remember, finger tightness alone suffices for this connection to avoid damaging the delicate connector mechanism. The FluidLoc cable requires no special handling beyond standard cable routing practices.

Frequently Asked Questions (FAQ)

1. What is the total length of this specific probe model?
The Bently Nevada 330708-00-10-90-11-00 features a 9.0-metre (29.5 feet) total length, as the "90" option in its part number designates. This extended length suits installations where the junction box sits far from the measurement point.

2. What type of cable does this probe use?
This model utilizes FluidLoc cable with a miniature coaxial ClickLoc connector and connector protector. The FluidLoc design offers superior resistance to fluid ingress, making it ideal for oil-rich environments.

3. What thread size does this probe use?
The 330708-00-10-90-11-00 uses a 5/8-18 UNF thread with a maximum thread engagement of 0.938 inches. This larger thread size provides additional mounting strength compared to the 1/2-20 option.

4. What materials compose the probe's construction?
The probe tip uses Polyphenylene sulfide (PPS), and the probe case uses AISI 304 stainless steel (SST) . This combination provides excellent durability and corrosion resistance.

5. What torque value do we recommend for the probe case?
For the 330708-00-10-90-11-00, we recommend an installation torque of 15.2 N•m (133 in•lb). The maximum allowable torque is 45.2 N•m (400 in•lb).
