Description

Bently Nevada 330101-00-20-10-02-05 3300 XL 8 mm Proximity Sensor

The Bently Nevada 330101-00-20-10-02-05 is a high-reliability eddy current proximity sensor specifically engineered for non-contact measurement of shaft vibration and position. As a foundational component of the 3300 XL series, this probe translates the distance between the probe tip and the target material into a precise voltage signal. This data is essential for the continuous monitoring of critical rotating machinery, allowing for the early identification of mechanical issues such as unbalance, misalignment, and bearing degradation.

Precision Engineering for High-Stakes Monitoring

This 8 mm probe is designed to provide a standard 200 mV/mil (8 V/mm) output when integrated into a complete 3300 XL Transducer System. Specifically, the 330101-00-20-10-02-05 configuration includes a 2.0-inch threaded length and a 1.0-meter integral cable, making it ideal for standard machine casing penetrations. Furthermore, the sensor is calibrated for AISI 4140 steel targets, ensuring laboratory-grade linearity and accuracy in field deployments. As a result, plant operators can rely on stable, drift-free data even during rapid thermal cycling or high-velocity shaft rotation.

Technical Specification Matrix

Industrial Durability and Compliance

The 330101-00-20-10-02-05 is built to endure the most hostile industrial environments, from steam turbine housings to offshore compressor stations. Moreover, the probe tip is hermetically sealed with polyphenylene sulfide (PPS), providing total resistance to moisture, lubricating oils, and chemical solvents. In addition, this model includes a factory-installed connector protector, which prevents fluid ingress and mechanical damage to the coaxial interface. Therefore, this probe is highly recommended for applications where long-term sensor survival is as critical as measurement precision.

FAQ

What is the purpose of the 05 Connector Protector option?

The 05 option indicates that the probe comes with a specialized sleeve over the ClickLoc connector. Specifically, this protector prevents oil and environmental contaminants from entering the connection point between the probe and the extension cable, which is a common cause of signal noise.

Can I use this probe with a 5-meter or 9-meter system?

The 1.0-meter integral cable on this probe is compatible with both 4.0-meter and 8.0-meter extension cables. Furthermore, you must ensure that your 3300 XL Proximitor sensor is calibrated to match the resulting total system length (either 5 or 9 meters) to maintain accuracy.

Does this probe require a specific target material?

Standard calibration is for AISI 4140 steel. Accordingly, if your shaft is made of a different alloy, such as 17-4 PH stainless steel, the scale factor may change, necessitating a custom calibration within the Proximitor or monitoring rack.

What is the maximum temperature rating for this sensor?

This probe is rated for operation in temperatures ranging from -51 °C to +177 °C. Ultimately, this high-temperature capability allows it to be installed deep within the hot sections of gas turbines and other thermal-intensive machinery.
