Technical Functionality and Measurement Principle

The Bently Nevada 330703-000-070-10-02-00 operates as a high-precision displacement sensor within the 3300 XL 11 mm Proximity Transducer System. This eddy current probe measures the dynamic and static distance between the probe tip and a conductive target surface, such as a turbine shaft. Because this model utilizes an 11 mm tip diameter, it achieves a significantly larger linear range compared to standard 8 mm probes. This expanded measuring window allows the sensor to monitor machinery with greater axial float or significant thermal expansion, ensuring that the system captures critical data even during extreme mechanical shifts.

Strategic Industrial Applications

Industrial facilities deploy the 330703 series primarily when the machine’s expected movement exceeds the 2.0 mm limit of standard sensors. Consequently, this probe is a staple in Turbine Supervisory Instrumentation (TSI) for large-scale power generation and oil and gas processing. Furthermore, the probe’s design features a polyphenylene sulfide (PPS) tip, which prevents fluid ingress and maintains electrical insulation in harsh environments.

Primary use cases include:

  • Monitoring axial (thrust) position in large steam and gas turbines
  • Measuring differential expansion between the machine rotor and casing
  • Tracking radial vibration in heavy-duty fluid-film bearings
  • Providing phase reference signals in high-speed rotating assets

Integration and System Reliability

The 330703-000-070-10-02-00 integrates directly with a 3300 XL extension cable and an 11 mm Proximitor Sensor. Because Bently Nevada optimizes the 3300 XL series for signal stability, this probe effectively resists electromagnetic interference (EMI) and eliminates “crosstalk” between adjacent sensors. Moreover, the patented ClickLoc connector ensures a secure, vibration-proof link between the probe and the extension cable. By installing this transducer, maintenance teams receive the high-resolution data necessary to implement predictive maintenance, thereby reducing the risk of unplanned downtime and extending the service life of critical rotating equipment.

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. The analog voltage output from the associated Proximitor Sensor can also be integrated with other third-party PLCs, DCS, and data acquisition systems capable of processing a -2 to -18 Vdc signal.

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.
