Technical FAQ

Q: What systems is the 21000-34-10-20-058-04-02 compatible with?
A: The 21000-34-10-20-058-04-02 contains a 3300 XL 8 mm probe. This probe is a component of a complete transducer system that must also include a 3300 XL extension cable and a 3300 XL Proximitor Sensor. The complete transducer system is directly compatible with Bently Nevada monitoring systems, including the 3500 Series, 3300 Series, and the Orbit 60 Series. It provides a standard analog voltage signal (typically 2 to 18 Vdc or -2 to -18 Vdc) to the monitor's input module for processing.

Q: What are the installation requirements?
A: Installation requires a machined mounting boss on the machine case with a 3/4 - 14 NPT tapped hole. The surface of the boss must be perpendicular to the shaft centerline to ensure accurate measurement. Use an appropriate thread sealant (e.g., PTFE tape or liquid sealant rated for the process temperature and fluid) on the NPT threads to create a secure seal and prevent loosening. The assembly should be tightened to the specified torque value. After mechanical installation, the probe gap must be set by adjusting the probe within the housing to achieve the desired DC voltage, typically the center of its linear range (e.g., -10 Vdc for a standard 80 mil / 2 mm range), before locking it in place.

330102-00-60-10-01-05 | Bently Nevada | 3300 XL 8 mm Proximity Probes

330102-00-60-10-01-05 | Bently Nevada | 3300 XL 8 mm Proximity Probes

Technical Overview

The Bently Nevada 330102-00-60-10-01-05 is an 8 mm reverse-mount eddy current proximity probe designed for non-contact measurement of vibration and displacement. It functions as a core component of the 3300 XL 8 mm Proximity Transducer System, which also includes an extension cable and a Proximitor Sensor. The probe operates by having the Proximitor Sensor generate a high-frequency radio frequency (RF) signal, which is transmitted through the extension cable and radiated from the probe's tip into a small electromagnetic field. When a conductive target, such as a machine shaft, enters this field, eddy currents are induced on its surface. These currents create a secondary magnetic field that opposes the primary field, causing a measurable change in the RF signal's amplitude. This change is directly proportional to the gap between the probe tip and the target surface. The Proximitor Sensor demodulates this signal, converting it into a DC voltage that accurately represents the physical distance. This conditioned voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500, for real-time analysis of radial vibration, axial position, and shaft speed.
