3300 XL 11mm Probe | Bently Nevada 330707-00-15-50-01-CN

Product Introduction

The Bently Nevada 330707-00-15-50-01-CN 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 armored 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 1.5 inches, as indicated by the "15" option in the part number. This medium case length offers balanced mounting flexibility for various installation scenarios. Furthermore, the electrical characteristics directly impact signal quality. The probe cable employs a 75 Ω triaxial design with fluoroethylene propylene (FEP) insulation. This 5.0-metre probe exhibits a specific DC resistance between the center and outer conductors, measuring 7.2 ± 0.8 ohms. This precise resistance value ensures accurate and consistent output from the Bently Nevada 330707-00-15-50-01-CN.

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. The connector protector adds an extra layer of defense against physical damage and contamination. Moreover, the armored casing option on this model adds protection against crushing and abrasion, thereby extending the probe's service life in demanding industrial settings.

It is important to note that 5.0-metre probes are specifically designed for use with the five metre Proximitor Sensor only. Using this probe with incompatible extension cables or sensors will result in incorrect measurement readings.

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 1/2-20 UNF thread with a maximum thread engagement of 0.750 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 330707-00-15-50-01-CN to perform within its design limits across diverse industrial applications.

Installation Guidelines

Proper installation of the Bently Nevada 330707 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 0.750 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. Then, 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.

Finally, verify that you are using the five metre Proximitor Sensor with this 5.0-metre probe. Mismatching cable lengths will produce inaccurate measurement data and may damage the monitoring system.

Frequently Asked Questions (FAQ)

1. What does the "CN" agency approval option mean for this probe?
The "CN" designation on the Bently Nevada 330707-00-15-50-01-CN indicates country-specific approval. This typically refers to China-specific certifications such as CCC or NEPSI, ensuring compliance with local regulatory requirements.

2. Why must I use a five metre Proximitor Sensor with this probe?
The 330707-00-15-50-01-CN features a 5.0-metre total length, and Bently Nevada designs these probes specifically for use with the five metre Proximitor Sensor only. Using any other cable length will produce inaccurate measurement readings.

3. What is the overall case length of this model?
This probe features a 1.5-inch overall case length, which the "15" option in its part number designates. This medium case length provides balanced mounting flexibility.

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 330707-00-15-50-01-CN, 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).
