21504-00-32-10-02 | Bently Nevada | Vibration Probe
Technical Overview
The Bently Nevada 21504-00-32-10-02 is a 3300 NSv series proximity vibration probe, a fundamental component of an eddy current transducer system designed for non-contact displacement and vibration measurement on rotating machinery. Its primary function is to measure the distance (gap) between the probe tip and a conductive target material, typically a machine shaft. The probe operates by generating a high-frequency radio frequency (RF) field from its tip coil. When brought near the conductive target, this field induces eddy currents on the target's surface. These eddy currents alter the impedance of the probe's coil system. This change in impedance is detected by an associated Proximitor Sensor, which demodulates the signal into a voltage directly proportional to the probe-to-target gap. This analog voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500 Machinery Protection System, for real-time analysis, trending, and alarming. The 21504-00-32-10-02 is constructed with a stainless steel case for durability in industrial environments and is specifically configured with a 320 mm case length and a 1.0-meter integral cable.

Technical FAQ
Q: What systems is the 21504-00-32-10-02 compatible with?
A: The 21504-00-32-10-02 probe is a component of the Bently Nevada 3300 NSv Proximity Transducer System. For correct operation, it must be used in conjunction with a 3300 NSv extension cable and a 3300 NSv Proximitor Sensor. The output from the Proximitor Sensor is compatible with Bently Nevada monitoring systems, including the 3500 and 3300 series, as well as any data acquisition system, PLC, or DCS capable of accepting a -24 Vdc powered, 7.87 V/mm (200 mV/mil) analog signal.
Q: What are the installation requirements?
A: Proper installation is critical for measurement accuracy. The probe must be mounted perpendicular to the target surface using a rigid bracket. The physical gap should be set to place the DC output voltage in the middle of the system's linear range, typically -10 Vdc. The target area on the shaft must be at least 10.7 mm (0.42 in) in diameter, smooth (0.4 to 0.8 µm / 16 to 32 µin rms), and free of any electrical or magnetic irregularities (e.g., chrome plating, magnetised spots). Cable routing must avoid high-voltage power lines and other sources of electromagnetic interference. All ClickLoc connectors must be fully engaged to ensure a secure connection.
330703-00-100-10-11-CN | Bently Nevada | 3300 XL 11 mm Proximity Probes
Technical Overview
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.

Technical FAQ
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.
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.

It is not electrically or mechanically compatible with components from other transducer series, such as the 7200 or 3000 series.
Q: What are the installation requirements?
A: As a reverse-mount probe, the 330102-00-60-10-01-05 is installed from inside the machine housing, with the probe body extending outward. A clearance hole must be drilled through the machine case to accommodate the 8 mm probe tip. The target area on the observed shaft must be smooth, free of surface defects, and have a minimum diameter of 10.7 mm (0.42 in) to ensure measurement accuracy. The probe's gap should be set to the center of its linear range, typically corresponding to -10.0 Vdc. The ClickLoc connector must be tightened to the specified torque to ensure a secure, environmentally sealed connection. Cable routing must avoid areas of extreme heat, physical abrasion, and proximity to high-voltage power lines to maintain signal integrity.
330102-00-12-05-02-05 | Bently Nevada | 3300 XL 8 mm Proximity Probes
Technical Overview
The Bently Nevada 330102-00-12-05-02-05 is a 3300 XL 8 mm reverse mount proximity probe, a component of an eddy current transducer system designed for non-contact displacement and vibration measurement on rotating machinery. The probe functions by emitting a high-frequency radio frequency (RF) signal from its encapsulated tip. When positioned near a conductive target material, such as a machine shaft, this RF field induces eddy currents on the surface of the target. The interaction between the probe's field and the eddy currents creates an impedance change in the probe's coil, which is directly proportional to the gap between the probe tip and the target surface. This raw signal is transmitted through its integral 0.5-meter cable to a 3300 XL extension cable and subsequently to a 3300 XL Proximitor Sensor. The Proximitor Sensor demodulates and linearizes the signal, producing a precise DC voltage output that corresponds to the physical gap. This conditioned signal is then supplied to a Bently Nevada 3500 Series monitoring system for continuous machine protection, diagnostics, and data logging.
