Technical Overview
The Bently Nevada 21000-34-10-20-058-04-02 is a rigid proximity probe housing assembly designed for the external mounting of proximity probes on machinery casings. Its primary function is to provide a secure, environmentally sealed, and mechanically protected housing for a non-contacting eddy current proximity probe. This specific assembly, constructed from 304 Stainless Steel, ensures robust performance in corrosive industrial environments. It positions a 3300 XL 8 mm probe at a fixed distance from the mounting surface, defined by its 3.4-inch standoff dimension.

Technical FAQ
Q: What systems is the 21000-34-10-20-058-04-02 compatible with?
A: The 21000-34-10-20-058-04-02 contains a 3300 XL 8 mm probe. This probe is a component of a complete transducer system that must also include a 3300 XL extension cable and a 3300 XL Proximitor Sensor. The complete transducer system is directly compatible with Bently Nevada monitoring systems, including the 3500 Series, 3300 Series, and the Orbit 60 Series. It provides a standard analog voltage signal (typically 2 to 18 Vdc or -2 to -18 Vdc) to the monitor's input module for processing.
Q: What are the installation requirements?
A: Installation requires a machined mounting boss on the machine case with a 3/4 - 14 NPT tapped hole. The surface of the boss must be perpendicular to the shaft centerline to ensure accurate measurement. Use an appropriate thread sealant (e.g., PTFE tape or liquid sealant rated for the process temperature and fluid) on the NPT threads to create a secure seal and prevent loosening. The assembly should be tightened to the specified torque value. After mechanical installation, the probe gap must be set by adjusting the probe within the housing to achieve the desired DC voltage, typically the center of its linear range (e.g., -10 Vdc for a standard 80 mil / 2 mm range), before locking it in place.
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.

330881-28-04-034-06-02 | Bently Nevada | PROXPAC XL Proximity Transducer
Technical Overview
The Bently Nevada 330881-28-04-034-06-02 is an integrated PROXPAC XL Proximity Transducer system. This component combines an 8 mm proximity probe, an extension cable, and a signal conditioner into a single, factory-calibrated assembly, which eliminates the need for individual component calibration in the field. The transducer operates on the eddy current principle. The probe tip emits a high-frequency radio frequency (RF) signal, which induces eddy currents on the surface of a conductive machine element, such as a rotating shaft. The transducer's internal circuitry measures the impedance changes resulting from the interaction between the RF field and the eddy currents. This impedance is directly proportional to the physical gap between the probe tip and the target surface. The integrated signal conditioner demodulates this signal and provides a continuous DC voltage output that is precisely proportional to the measured gap. This output voltage is then transmitted to a monitoring system, such as the Bently Nevada 3500 series, for analysis of vibration, axial position, or rotational speed. The construction of the 330881-28-04-034-06-02 ensures high signal integrity by minimizing interconnections, making it suitable for critical machinery monitoring applications.

Operational Capabilities
In Oil & Gas and Power Generation applications, the 16710-33 interconnect cable demonstrates high reliability in continuous-duty environments. Its robust construction is engineered to withstand the typical ambient conditions of a plant floor, including moderate vibration and wide temperature swings as specified by its -30°C to +100°C operating range. The cable's performance is defined by its ability to maintain signal integrity for critical measurements on assets like gas and steam turbines, centrifugal and reciprocating compressors, and large pump systems. The multi-layer shielding is effective in mitigating electrical noise from variable frequency drives (VFDs), motors, and high-voltage lines, preventing signal corruption that could lead to false alarms or missed protection events. The design focuses on long-term stability, with high-quality connectors and strain relief that prevent intermittent connections, a common failure point in industrial settings. The 16710-33 is an integral component in achieving the high Mean Time Between Failure (MTBF) rates expected from a SIL-rated machinery protection system.

Technical FAQ
Q: What systems is the 16710-33 compatible with?
A: The 16710-33 is specifically designed for use with the Bently Nevada 3500 Machinery Protection System. It is used to connect various 3500 I/O modules, such as the 3500/40M Proximitor Monitor, 3500/42M Proximitor/Seismic Monitor, and 3500/45 Position Monitor, to their corresponding external termination blocks (e.g., 3500/25 Keyphasor I/O, 3500/40 External Termination Block) or internal termination I/O modules. Compatibility is dependent on the specific I/O module and termination type being used in the 3500 rack configuration.
Q: What are the installation requirements?
A: Proper installation is critical for system performance. First, ensure all power to the 3500 rack is de-energized before installation. Securely fasten the D-sub connector of the 16710-33 to the rear of the designated I/O module using the integrated jackscrews. Route the cable through designated cable trays, avoiding sharp bends (maintain a minimum bend radius of 10x the cable diameter), pinch points, and proximity to high-voltage power cables to prevent physical damage and noise induction. Land the pre-stripped conductors of the pigtail end onto the correct terminals of the associated terminal block, following the wiring diagram specific to the monitor and transducer type. Ensure proper strain relief is applied to the cable at both ends. The cable's shield drain wire must be terminated correctly, typically at the rack chassis ground terminal only, to prevent ground loops per Bently Nevada system grounding guidelines.
