Bently Nevada 330104-00-16-10-02-00 3300 XL 8 mm Proximity Probe

Introduction to the Bently Nevada 330104-00-16-10-02-00 Proximity Probe

In rotating machinery monitoring, accurate vibration measurement is critical for preventing unplanned downtime. The Bently Nevada 330104-00-16-10-02-00, part of the 3300 XL 8 mm Proximity Probe series, delivers reliable displacement sensing for turbomachinery, compressors, and pumps. This probe features an M10 x 1 threaded tip with armor for enhanced durability in harsh environments. With a 1.0 meter (3.3 feet) total length and a miniature coaxial ClickLoc connector, it integrates seamlessly into existing monitoring systems. The probe tip is made of polyphenylene sulfide (PPS), while the case is constructed from AISI 303 or 304 stainless steel, ensuring long service life.

Technical Specifications Breakdown

Key specifications define the performance of the 330104-00-16-10-02-00. The unthreaded length is 00 mm, and the overall case length is 160 mm. The total length option is 10, representing 1.0 meter (3.3 feet). The connector type is a miniature coaxial ClickLoc connector with standard cable. The probe tip material is polyphenylene sulfide (PPS), and the probe case material is AISI 303 or 304 stainless steel (SST). The nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.59 ± 0.50 ohms for the 1.0 meter length. These parameters ensure consistent electrical performance for accurate gap and vibration measurements.

Industry Applications

This proximity probe is widely used in critical rotating machinery such as steam turbines, centrifugal compressors, and large electric motors. In these applications, the 330104-00-16-10-02-00 provides real-time shaft displacement data, enabling early detection of bearing wear, imbalance, or misalignment. The M10 x 1 thread and armor make it suitable for high-pressure environments, as the probe is designed to seal differential pressure between the tip and case using a Viton O-ring. By integrating this probe into a condition monitoring system, plant operators can reduce unplanned outages and extend equipment life.

Installation & Setup Guidance

Proper installation is essential for accurate readings. When mounting the 330104-00-16-10-02-00, ensure the probe tip is gapped at 1.27 mm (50 mils) relative to an AISI 4140 steel target for optimal performance. The probe requires a -17.5 Vdc to -26 Vdc power supply when installed with a non-incendive circuit per drawing 140979, consuming a maximum of 12 mA. Use the miniature coaxial ClickLoc connector to attach standard extension cables. Avoid operating at voltages more positive than -23.5 Vdc, as this can reduce the linear range. Always verify the thread compatibility (M10 x 1) before installation.

Maintenance & Reliability

To maintain measurement accuracy, periodically inspect the probe tip for contamination or damage. The PPS tip and stainless steel case resist corrosion and wear, but regular visual checks are recommended. The Viton O-ring seal should be verified for integrity, especially in high-pressure applications. The 330104-00-16-10-02-00 is designed for long-term reliability, with a nominal DC resistance tolerance of ±0.50 ohms ensuring stable signal transmission. For continued performance, follow the manufacturer's guidelines for system calibration using an AISI 4140 steel target.

Compatibility & Integration

The 330104-00-16-10-02-00 is compatible with Bently Nevada 3300 XL 8 mm Proximitor Sensors and extension cables. It accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm probe and extension cable. The system accuracy and interchangeability specifications apply only when using solely 3300 XL 8 mm components. For integration into existing monitoring systems, ensure the power supply meets the -17.5 Vdc to -26 Vdc requirement. The probe's output resistance is 50 Ω, and sensitivity is less than 2 mV change per volt change in input voltage, making it suitable for most industrial vibration monitoring setups.

Selection Guide & Purchasing Advice

Before purchasing the 330104-00-16-10-02-00, verify the required unthreaded length, overall case length, and total length to match your application.
