Bently Nevada 330702-00-50-50-02-CN 11mm Probe

3300 XL 11 mm Proximity Probe 330702-00-50-50-02-CN

Product Introduction

The Bently Nevada 330702-00-50-50-02-CN belongs to the trusted 3300 XL series. This 11 mm proximity probe is a precision sensor for shaft relative vibration and position monitoring. It is an ideal choice for critical rotating machinery. Furthermore, its robust construction supports long-term reliability in harsh industrial environments. This model includes a stainless steel armor for enhanced cable protection. The probe uses a 1/2-20 UNF thread for standard mounting. Meanwhile, its total length of 5.0 meters matches perfectly with the compatible five-meter Proximitor Sensor. The connector type is a miniature coaxial ClickLoc, which ensures a secure and vibration-proof connection. Specifically, this probe meets country-specific agency approvals (CN). Its measurement linearity and stability make it a preferred component for predictive maintenance systems.

Mechanical and Environmental Parameters

This Bently Nevada 3300 XL probe withstands high-pressure environments, although it is not pressure-tested before shipping. Its design seals differential pressure between the tip and case. For applications requiring pressure testing, you must contact the custom design department. The connector-to-connector torque recommendation is simply finger tight. The maximum torque for the connector is 0.565 N•m. Over-tightening this connection can damage the coaxial interface. The overall case length is 5.0 inches. The unthreaded length option is 0 inches, making the entire case length effectively available for threading or mounting.

Furthermore, the stainless steel armor provides extra crush and abrasion resistance. This armor is crucial for installations where the cable may rub against machinery frames. The operating temperature range is consistent for both storage and operation. This wide range allows for deployment in both extreme cold and high-heat zones. Additionally, the probe has a shipping weight of just 0.17 kg. The gross weight with packaging is approximately 0.35 kg. This lightweight feature simplifies logistics and handling. The probe's material selection ensures long service life, reducing maintenance frequency. Therefore, this sensor is a cost-effective solution for continuous condition monitoring.

Installation and Mounting Guide

Proper installation of the 330702-00-50-50-02-CN ensures accurate readings and prevents damage. First, inspect the 1/2-20 UNF threads for any debris or damage. Then, apply a small amount of anti-seize compound, but avoid the probe tip. Next, screw the probe into the mounting hole finger-tight. Afterward, use a torque wrench to tighten it to the recommended 15.2 N•m. This torque is much lower than the maximum rating. Over-torquing can distort the case and affect the internal coil.

Meanwhile, route the cable with a bending radius greater than 25.4 mm. Sharp bends can degrade signal quality over time. Use cable ties to secure the cable at regular intervals. This reduces mechanical strain on the connector. The connector should be mated with the Proximitor Sensor cable until you feel a positive click. Then, tighten the connector by hand only, as the maximum torque for the connector is 0.565 N•m. Remember, this 5.0-meter probe version is specifically engineered for use with the five-meter Proximitor Sensor. Using it with a different length sensor may lead to calibration errors. Finally, seal the mounting hole with appropriate thread sealant if the application is pressurized. However, ensure the sealant does not contact the probe tip.

Frequently Asked Questions (FAQ)

1. Can the 330702-00-50-50-02-CN be used with a 9-meter Proximitor?
No. This specific 5.0-meter probe version is designed exclusively for use with the five-meter Proximitor Sensor. Using it with other lengths will cause measurement inaccuracies.

2. What is the purpose of the stainless steel armor?
The armor protects the cable from mechanical damage, such as abrasion or crushing, which is common in industrial machinery environments. It increases the cable's durability.

3. How do I know if the probe is damaged?
First, check the DC resistance between the center and outer conductors. It should be 7.2 ± 0.8 ohms. Additionally, inspect the tip for physical damage. Then, verify the connector is clean and undamaged.

4. Is this probe submersible or pressure-tested?
No. The probe is sealed with a Viton O-ring to handle differential pressure. However, it is not pressure-tested before shipment. For pressure testing, you must contact the custom design department.

5. What is the recommended shipping carrier?
We recommend shipping via FedEx, UPS, or DHL. These carriers ensure safe and timely delivery. The packaging meets the standard requirements for these couriers.
