Furthermore, the 3300 XL series is fully compliant with the American Petroleum Institute (API) 670 standard for accuracy and interchangeability. This makes it a preferred choice for:
- Radial shaft vibration monitoring in steam and gas turbines
- Axial thrust position tracking in high-pressure compressors
- Eccentricity and shaft alignment measurements
- Speed and Keyphasor reference applications
Installation and System Integration
For a complete measurement loop, technicians must pair this 1.0-meter probe with a 4.0-meter extension cable (to reach a 5.0-meter system) or an 8.0-meter extension cable (for a 9.0-meter system). The probe should be installed using the M10 x 1 metric threads and gapped appropriately—typically at 1.27 mm (50 mils)—to ensure the target remains within the probe’s linear range.

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.

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).

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.

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.
