Bently Nevada 330104-00-13-10-02-CN Proximity Transducer for 3300 Series

Bently Nevada 330104-00-13-10-02-CN: Proximity Transducer for 3300 Series

The Bently Nevada 330104-00-13-10-02-CN is an eddy-current proximity transducer engineered as a precision sensing element within the Bently Nevada 3300 Series vibration monitoring architecture. Rather than functioning as a standalone sensor, this transducer is designed to operate as an integrated node within a layered industrial automation system — connecting the mechanical domain of rotating machinery to the digital control and protection infrastructure of modern process plants. Its role spans the signal acquisition layer, feeding real-time shaft displacement data upward through the monitoring system to the control layer, safety layer, and ultimately to the human-machine interface and historian platforms that govern plant-wide decision-making.

In turbomachinery protection systems — covering steam turbines, gas turbines, compressors, pumps, and gearboxes — shaft vibration and position data are not optional diagnostics. They are the primary inputs to trip logic, alarm management, and predictive maintenance workflows. The 330104-00-13-10-02-CN delivers the radial vibration and axial position signals that the 3300 Series monitor rack depends upon to execute these functions with sub-millisecond response times. Its 5-metre cable configuration and -18 mm tip geometry are matched to the mechanical clearances and installation envelopes common in heavy industrial turbomachinery bearing housings.

System Compatibility Notes

The 330104-00-13-10-02-CN does not operate in isolation. Its value is fully realised only when it is correctly integrated into the broader Bently Nevada 3300 Series monitor rack and the plant-wide control architecture surrounding it. In a typical turbomachinery protection system, this transducer is paired with a Bently Nevada 330180-X1-05 Proximitor Sensor — the signal conditioning module that powers the probe, linearises the output, and delivers a buffered analogue voltage to the monitor card. The monitor card, typically a 3300/16 Dual Vibration Monitor or a 3300/20 Radial Vibration Monitor, processes the signal against configurable alarm and trip setpoints, issuing relay outputs to the turbine control system or emergency shutdown (ESD) relay logic.

At the control layer, the 3300 Series rack communicates with the plant DCS or safety instrumented system (SIS) via hardwired relay contacts or, in more modern installations, through a Bently Nevada 3500/92 Communication Gateway Module using Modbus TCP or OPC-DA protocols. This gateway bridges the condition monitoring domain with the process control domain, enabling the DCS — whether a Honeywell Experion, Emerson DeltaV, or Yokogawa CENTUM — to incorporate vibration trip status into its cause-and-effect matrix without requiring separate signal conditioning infrastructure.

Power to the 3300 Series rack is supplied through a 3300/05 Power Supply Module, which accepts 115/230 VAC or 24 VDC plant power and distributes regulated -24 VDC to each Proximitor channel. In critical applications, dual redundant power supply modules are installed in parallel to eliminate the power supply as a single point of failure. The rack itself is housed in a 3300/01 Rack or 3300/03 Rack, which provides the backplane interconnect, grounding bus, and terminal block interface for field wiring.

At the human-machine interface layer, vibration data from the 330104-00-13-10-02-CN is visualised in real time through Bently Nevada System 1 Software, which aggregates data from multiple 3300 Series racks across the plant, displays trend plots, orbit diagrams, and Bode plots, and supports alarm rationalisation workflows. For field engineers performing commissioning or troubleshooting, a ADRE 408 DSPi Data Acquisition System can be connected directly to the buffered output of the Proximitor to capture high-resolution waveform data without interrupting the online monitoring system.

In axial position monitoring applications — particularly for thrust bearing wear detection on steam turbines — the 330104-00-13-10-02-CN is deployed alongside a 3300/25 Thrust Position Monitor, which provides dual-channel differential measurement with configurable danger and alert setpoints. The combination of radial and axial transducers on a single shaft provides the complete mechanical picture required for API 670-compliant machinery protection.

Industrial Application Notes

The 330104-00-13-10-02-CN finds its primary application in process industries where rotating machinery is central to production continuity and where downtime carries significant financial and safety consequences.

In power generation — including coal-fired, gas-fired, and combined-cycle plants — this transducer is installed on steam turbine shafts to monitor journal bearing vibration and rotor eccentricity during startup, steady-state operation, and shutdown. The data it provides is essential for operators to assess rotor thermal bow, bearing wear progression, and the approach to critical speed during run-up sequences.

In petrochemical and refinery applications, the 330104-00-13-10-02-CN is deployed on centrifugal compressors in ethylene crackers, hydrogen reformers, and LNG liquefaction trains. These machines operate continuously for multi-year intervals between turnarounds, making real-time vibration monitoring the primary tool for detecting developing faults — rotor imbalance, seal degradation, impeller fouling — before they escalate to forced outages.

In water and wastewater treatment, large vertical turbine pumps and centrifugal blowers equipped with 3300 Series monitoring systems use this transducer to detect bearing deterioration and shaft misalignment, enabling condition-based maintenance scheduling that reduces both maintenance cost and unplanned service interruptions.

In mining and minerals processing, the transducer is applied to large ball mill drives, SAG mill pinion bearings, and slurry pump shafts, where the harsh environment — high dust, vibration, and temperature — demands a robust, field-proven sensing solution with a proven track record in continuous duty applications.

Across all these industries, the 330104-00-13-10-02-CN contributes to a consistent outcome: earlier fault detection, reduced unplanned downtime, extended machinery life, and a defensible maintenance record that satisfies both internal reliability engineering standards and external regulatory requirements.

Product Compatibility FAQ

Q1: Is the 330104-00-13-10-02-CN directly compatible with all 3300 Series monitor cards, and does it require a specific Proximitor model?
The 330104-00-13-10-02-CN is designed for use with the Bently Nevada 3300 Series monitor rack and requires a compatible Proximitor/Seismic Monitor — typically the 330180 series — to provide the -24 VDC excitation and signal conditioning. The Proximitor output connects directly to the monitor card input. Compatibility is determined by the probe tip diameter, cable length, and target material; the -18 mm configuration of this part number is matched to the standard 3300 Series channel input range. Always verify the specific monitor card model (3300/16, 3300/20, 3300/25, or 3300/55) against the system configuration drawing before installation.

Q2: Can this transducer be integrated into a DCS or SIS architecture, and what communication path is used?
Yes. The 330104-00-13-10-02-CN feeds its analogue signal to the 3300 Series monitor, which provides hardwired relay contact outputs (alarm and danger) that can be wired directly into a DCS digital input card or SIS logic solver. For digital integration, the 3500/92 Communication Gateway Module supports Modbus TCP and OPC-DA, enabling the DCS to read vibration values, alarm states, and channel status over Ethernet. This system integration approach allows vibration data to participate in plant-wide cause-and-effect logic, historian trending, and advanced process control without requiring a separate data acquisition system.

Q3: What does the Warranty and support terms confirmed before quote cover, and what support is available for long-term maintenance and spare parts supply?
