SKU: 330104-01-08-50-01-CN
Bently Nevada 330104-01-08-50-01-CN 3300 XL 8mm Proximity Probe
The Bently Nevada 330104-01-08-50-01-CN is a high-performance 3300 XL 8mm proximity probe designed for critical machinery protection. Featuring a 3/8-24 UNF thread and specialized “-CN” certification, it provides accurate non-contact vibration and position data for turbines, compressors, and pumps in harsh industrial environments.
Technical Functionality
The Bently Nevada 330104-01-08-50-01-CN serves as a specialized eddy current sensor designed for non-contacting vibration and displacement measurements. This probe detects the relative position and dynamic motion of a rotating shaft by generating a high-frequency electromagnetic field. When the shaft moves, it creates eddy currents that alter the probe’s impedance, which the Proximitor Sensor then converts into an accurate voltage signal. Because it utilizes the 3300 XL platform, this transducer provides superior scale factor stability and remains highly resistant to temperature-induced drift.
Operational Durability
Engineers designed this specific probe model to excel in the most volatile industrial environments. The 330104 series features a ruggedized construction that prevents moisture ingress and resists damage from corrosive lubrication fluids. Furthermore, the “-CN” designation indicates compliance with specific regional certifications, ensuring the unit meets rigorous safety and performance standards for localized markets. By utilizing a polyphenylene sulfide (PPS) probe tip and a stainless steel body, the sensor maintains long-term structural integrity even when subjected to high-pressure conditions within machinery housings.

330192-00-28-05-00 | Bently Nevada | 3300 XL 8 mm ETR Proximity Probes
Technical Overview
The Bently Nevada 330192-00-28-05-00 is an 8 mm Extended Temperature Range (ETR) proximity probe component of the 3300 XL Proximity Transducer System. Its primary function is to perform non-contact measurement of relative displacement on rotating and reciprocating machinery. The probe operates on an eddy current principle. When paired with a 3300 XL extension cable and Proximitor Sensor, it forms a tuned oscillator circuit that emits a high-frequency radio frequency (RF) field from the probe tip. This field induces eddy currents on the surface of the observed conductive target, typically a machine shaft. The interaction between the RF field and the eddy currents results in a change in the oscillator's amplitude, which is directly proportional to the gap between the probe tip and the target. The Proximitor Sensor demodulates this RF signal into a precise DC voltage. This voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500 Series, where it is processed to provide critical measurements including radial vibration, axial position (thrust), and rotational speed (when used in a Keyphasor configuration). The 330192-00-28-05-00 is constructed with a Polyphenylene Sulfide (PPS) tip and a stainless steel body, ensuring robust performance in high-temperature industrial environments.

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.

Technical FAQ
Q: What systems is the 330102-00-60-10-01-05 compatible with?
A: The 330102-00-60-10-01-05 probe is a component of the 3300 XL 8 mm Transducer System. For proper operation, it must be used with a 3300 XL extension cable and a 3300 XL Proximitor Sensor (e.g., part number 330180). This complete transducer system is fully compatible with Bently Nevada monitoring systems, including the 3500 Series Machinery Protection System and ADRE Sxp/408 DSPi data acquisition systems. 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.

Technical FAQ
Q: What systems is the 31000-16-05-00-100-03-02 compatible with?
A: The 31000-16-05-00-100-03-02 is an integral component of the Bently Nevada 3300 XL Proximity Transducer System. This system, which includes the probe, extension cable, and a 3300 XL Proximitor Sensor, is designed for direct interface with the Bently Nevada 3500 Machinery Protection System. It is also fully compatible with the legacy 3300 monitoring system.

Q: What are the installation requirements?
A: Proper installation is critical for accurate measurement. The machine case requires a mounting hole drilled and tapped for a 3/4-14 NPT thread. An appropriate thread sealant must be applied to the housing's male NPT threads to ensure a pressure-tight seal. The housing is then threaded into the machine case and tightened. The proximity probe is inserted into the housing and its axial position is adjusted to achieve the correct DC gap voltage, typically -10 Vdc for a standard 3300 XL 8 mm probe configuration. Once the gap is set, the probe is secured within the housing using its set screws. Proper system grounding, as detailed in Bently Nevada documentation, is mandatory for signal integrity.
