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.
The Bently Nevada 330703-00-100-10-11-CN is an 11 mm eddy current proximity probe designed for non-contact displacement and vibration measurement on rotating machinery. It functions as a core component of the 3300 XL 11 mm Transducer System, which also includes a matched extension cable and a 3300 XL 11 mm Proximitor Sensor. The system operates on the eddy current principle, where the Proximitor Sensor emits a high-frequency radio frequency (RF) signal through the probe and extension cable. This signal radiates from the probe tip, creating an 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 impedance. The Proximitor Sensor demodulates this signal to produce a DC voltage directly proportional to the gap between the probe tip and the target surface. This analog voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500 series, for real-time analysis of radial vibration, axial position, and shaft speed. The 330703-00-100-10-11-CN features a robust stainless steel case and a chemically resistant Polyphenylene Sulfide (PPS) tip, ensuring reliability in harsh industrial environments.

Q: What systems is the 330703-00-100-10-11-CN compatible with?
A: The 330703-00-100-10-11-CN probe must be used as part of a complete Bently Nevada 3300 XL 11 mm Transducer System. This requires a matching 3300 XL 11 mm Proximitor Sensor (e.g., part number 330780) and a 3300 XL 11 mm extension cable. It is not interchangeable with components from 5 mm or 8 mm transducer systems, as the scale factor and linear range are different. The complete transducer system provides a voltage output compatible with Bently Nevada monitoring systems, including the 3500 and 3300 series, as well as third-party PLCs, DCS, and data acquisition systems designed to accept a 3-wire, -24 Vdc powered eddy current probe input.
Q: What are the installation requirements?
A: Proper installation is critical for accurate measurements. The probe must be mounted perpendicular to the observed shaft surface using a rigid bracket. The target area on the shaft must be smooth (typically 0.4 to 0.8 µm / 16 to 32 µin Ra), free of chrome or other non-conductive plating, and clear of any residual magnetism or electrical runout. The probe must be gapped correctly by adjusting its distance to the shaft until the Proximitor Sensor output voltage is at the center of the linear range, typically -10.0 Vdc. The probe case locknut should be torqued to the specified value to prevent loosening. The integral cable and any extension cable should be secured to avoid strain on the connectors and routed away from high-voltage power cables to minimize interference.
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.
