The Bently Nevada 330881-16-00-180-03-02 PROXPAC XL is an integrated proximity transducer assembly. It combines a 3300 XL Proximitor sensor and probe into one unit, providing precise vibration and position data for Turbine Supervisory Instrumentation (TSI) systems
The Bently Nevada 330881-16-00-180-03-02 belongs to the PROXPAC XL Proximity Transducer Assembly series, which integrates a proximity probe, extension cable, and Proximitor sensor into a single, robust housing. This design effectively eliminates the need for separate Proximitor enclosures and external extension cables, significantly reducing installation complexity and potential points of failure. As part of a Turbine Supervisory Instrumentation (TSI) system, this transducer provides critical data for monitoring radial vibration, axial position, and speed in high-performance rotating machinery.
The alphanumeric suffix of the 330881 model defines specific physical and electrical characteristics:
The primary innovation of the PROXPAC XL is the internal integration of the 3300 XL Proximitor sensor. By housing the electronics directly within the probe assembly, Bently Nevada has streamlined the signal path, ensuring higher data integrity and easier maintenance. The assembly features an external adjustment capability, allowing technicians to gap the probe without disassembling the housing, which reduces downtime during commissioning and calibration.
Furthermore, the rugged construction ensures that the transducer maintains 100% OEM performance in challenging industrial environments characterized by high temperatures, mechanical vibration, and moisture. The seamless integration with existing Ethernet router communication services allows for digitized data transmission to the plant’s control system, facilitating advanced predictive maintenance and asset management.
Reliable vibration monitoring is mandatory for the longevity of heavy-duty rotating assets. This proximity transducer is typically deployed in:
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.

Q: What systems is the 330881-28-04-034-06-02 compatible with?
A: The 330881-28-04-034-06-02 is fully compatible with the Bently Nevada 3500 Machinery Protection System, specifically interfacing with modules such as the 3500/42M Proximitor/Seismic Monitor. It is also compatible with any PLC, DCS, or data acquisition system that can provide a -17.5 Vdc to -26 Vdc power supply and accept a proportional analog voltage input (typically configured for a range like -2 to -18 Vdc). The transducer is factory-calibrated for AISI 4140 steel; use with other target materials will require a different calibration or result in measurement inaccuracies.
Q: What are the installation requirements?
A: Installation requires both mechanical mounting and electrical wiring. The probe portion, with its 1/4-28 UNF thread, must be installed in a rigid bracket and its gap set relative to the machine shaft. The standard practice is to set the DC gap voltage to the center of the linear range (e.g., -10.0 V
