The Bently Nevada 330105-02-12-10-02-05 is a high-performance 3300 XL 8mm Proximity Probe featuring an M10x1 metric thread. Designed for critical machinery protection, it provides accurate non-contact vibration and position measurements in extreme temperatures ranging from -52°C to +177°C.
The Bently Nevada 330105-02-12-10-02-05 belongs to the 3300 XL 8mm Proximity Transducer System, the industry standard for measuring vibration and position on fluid-film bearing machines. This eddy current probe measures the distance between the probe tip and the observed conductive target, such as a rotating shaft. By converting this physical distance into a proportional voltage, the probe allows the 3500 Monitoring System to track radial vibration, axial thrust, and phase reference (Keyphasor) data.
Precision-engineered for reliability, the 330105-02-12-10-02-05 utilizes a polyphenylene sulfide (PPS) tip that resists chemical corrosion and moisture penetration. Because the probe employs a non-contact measurement method, it suffers no mechanical wear during operation, ensuring a long lifecycle in high-speed rotating equipment. Maintenance teams commonly deploy these probes in:
For optimal performance, engineers must pair this probe with a matching 3300 XL Extension Cable and a 3300 XL Proximitor Sensor. The total length of the probe cable and extension cable must equal the calibrated length of the Proximitor (typically 5.0 or 9.0 meters). Furthermore, proper gapping—usually set at the center of the linear range—is essential to prevent “mechanical bottoming” or signal clipping. The included connector protector ensures that the coaxial connection remains isolated from oil and contaminants within the machine housing.
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.

The 330192-00-28-05-00 probe is engineered for high-reliability machine protection and condition monitoring in demanding industrial sectors. In Oil & Gas applications, its ETR specification (up to +260 °C) allows for installation on high-temperature machinery such as gas turbines, steam turbines, and centrifugal compressors, where probes are often located near hot casings or in high-temperature bearing housings. In Power Generation, it provides essential rotor dynamics data for turbine-generator sets, ensuring safe operation within design limits. The 3300 XL system, including the 330192-00-28-05-00 probe, is designed for high immunity to radio frequency interference (RFI/EMI), a common issue in industrial plants. Its robust construction with an AISI 304 stainless steel case provides excellent resistance to corrosion from hydrocarbons and other process chemicals. The system's stability and repeatability are critical for API 670 compliant machinery protection systems, providing accurate data for automatic shutdown logic and predictive maintenance analysis.
