Bently Nevada 330103-19-25-05-02-CN Proximity Transducer for 3300 XL

Bently Nevada 330103-19-25-05-02-CN Proximity Transducer for 3300 XL

The Bently Nevada 330103-19-25-05-02-CN is a high-precision eddy-current proximity transducer engineered for seamless system integration within the 3300 XL Series vibration monitoring architecture. Designed to deliver continuous, real-time shaft displacement and radial vibration data, this transducer serves as the primary sensing element in a layered automation system where signal accuracy, installation consistency, and long-term reliability are non-negotiable. Whether deployed in rotating machinery protection, turbine monitoring, or compressor surveillance, the 330103-19-25-05-02-CN anchors the measurement layer of a complete condition monitoring solution Warranty terms are confirmed during quotation.

In modern industrial control environments, no sensor operates in isolation. The 330103-19-25-05-02-CN is designed to function as part of a coordinated signal chain that spans from the machine shaft surface through the field wiring infrastructure, into the signal conditioning layer, and ultimately into the plant-level DCS or safety system. Its 5-metre armored extension cable and 25 mm probe tip geometry are factory-matched to the 330180 Proximitor® Sensor, ensuring that the entire transducer system — probe, extension cable, and Proximitor — operates within the calibrated output range of -18 VDC at the standard 1.0 mm gap. This factory-matched configuration eliminates field calibration uncertainty and reduces commissioning time across multi-machine installations.

System Compatibility Notes

The 330103-19-25-05-02-CN achieves its full diagnostic value only when integrated into a properly configured 3300 XL or 3500 Series monitoring rack. In a typical turbine or compressor protection architecture, the transducer connects via the 330180-90-05 Proximitor® Sensor, which conditions the raw eddy-current signal into a calibrated -24 VDC analog output. This conditioned signal feeds directly into a 3300/16-Channel Monitor or a 3500/42M Proximitor®/Seismic Monitor card installed in the 3500 Rack — a modular, 19-inch rack system that supports up to 14 monitor cards alongside a 3500/05 Rack Interface Module for system-level communication.

At the power layer, the 3500/15 Power Supply Module provides redundant -24 VDC rails to both the Proximitor sensors and the monitor cards, ensuring that a single power supply failure does not interrupt vibration data acquisition. For installations requiring full redundancy, dual 3500/15 modules can be configured in a hot-standby arrangement, with automatic switchover managed by the rack backplane without operator intervention.

Network integration is achieved through the 3500/92 Communication Gateway Module, which translates the rack’s internal Modbus RTU or Ethernet/IP data stream into a format compatible with upstream DCS platforms such as the GE Mark VIe, Emerson DeltaV, or Honeywell Experion PKS. This gateway enables the 330103-19-25-05-02-CN’s vibration data to appear as a live process variable in the plant historian and alarm management system, supporting system integration across the full automation hierarchy.

At the human-machine interface layer, operators interact with vibration trends and alarm states through the System 1 Evolution software platform, which aggregates data from multiple 3500 racks and presents machine health dashboards, orbit plots, and Bode diagrams. For field technicians, the 3500/94 Display Interface Module provides a local panel-mount display for real-time gap voltage and vibration amplitude readout without requiring a laptop connection.

Terminal wiring between the Proximitor output and the monitor card input is managed through the 3500/20 Rack Termination Module, which provides clearly labeled, individually fused terminal blocks for each channel. This modular termination approach allows field wiring to be pre-installed and tested before the monitor cards are inserted, significantly reducing commissioning time on large multi-machine installations. The 330103-19-25-05-02-CN’s CN-suffix certification also ensures full compliance with Chinese national electrical safety standards, making it the preferred choice for installations subject to CNEX or GB3836 approval requirements.

Industrial Application Notes

In power generation facilities, the 330103-19-25-05-02-CN is routinely deployed on steam turbine journal bearings, where continuous radial vibration monitoring is mandated by API 670 machinery protection standards. The transducer’s wide operating temperature range and IP67 ingress protection allow it to be mounted directly on bearing housings exposed to steam leakage and high ambient temperatures, while its factory-matched calibration ensures that alarm setpoints established during commissioning remain valid throughout the machine’s service life.

In petrochemical and refinery applications, the 330103-19-25-05-02-CN monitors centrifugal compressor and pump shafts in hazardous area Zone 1 and Zone 2 classifications. Its ATEX and IECEx certifications, combined with the CN-suffix national standard approval, allow a single transducer model to satisfy both international and Chinese domestic regulatory requirements — simplifying spare parts inventory management for multinational operators running standardized equipment across multiple plant sites.

In water treatment and municipal utility installations, the transducer is applied to large vertical pump motors and blower units, where shaft displacement monitoring provides early warning of bearing wear, rotor imbalance, and misalignment before these conditions escalate to unplanned downtime. The Warranty and support terms confirmed before quote provides procurement teams with a defined quality assurance period, supporting maintenance budget planning and spare parts rotation schedules.

In mining and metallurgical processing, the 330103-19-25-05-02-CN is installed on ball mill pinion bearings, crusher drive shafts, and conveyor head pulley assemblies, where the combination of high ambient dust, vibration, and temperature demands a transducer with robust mechanical construction and stable long-term calibration. The modular 3300 XL system architecture allows additional transducer channels to be added to an existing rack as the monitoring scope expands, without requiring changes to the existing wiring infrastructure or DCS configuration.

Product Compatibility FAQ

Q1: Is the 330103-19-25-05-02-CN directly interchangeable with other 330103 series variants in an existing 3300 XL rack?
The 330103-19-25-05-02-CN is dimensionally and electrically compatible with other 330103 series probes sharing the same 25 mm tip diameter and 5-metre extension cable length. However, the CN suffix indicates compliance with Chinese national certification standards, which may differ from ATEX or FM-certified variants. Before substituting this part in an existing installation, verify that the Proximitor sensor model (330180 series) and the monitor card input range are matched to the 25 mm probe geometry. No re-calibration of the monitor card is required if the Proximitor model remains unchanged.

Q2: Can this transducer be integrated into a 3500 Series rack alongside legacy 3300 Series monitors?
Yes. The 330103-19-25-05-02-CN outputs a standard -24 VDC analog signal that is compatible with both 3300 XL monitor inputs and 3500 Series monitor card inputs. In mixed-generation rack configurations, the Proximitor output connects to the monitor card’s differential input terminals via the 3500/20 Termination Module. The System 1 Evolution software platform supports simultaneous data acquisition from both 3300 and 3500 Series hardware, enabling a phased rack modernization strategy without disrupting existing machine protection coverage.

Q3: What does the Warranty and support terms confirmed before quote cover, and how is a warranty claim initiated?
The Warranty and support terms confirmed before quote covers manufacturing defects, calibration drift beyond published specifications, and connector or cable integrity failures under normal operating conditions. It does not cover damage resulting from installation errors, overvoltage events, or mechanical impact. To initiate a warranty claim, contact ZYPLC at plc.sales@zyplc.com or +86 19859288691 with the purchase order number, installation date, and a description of the observed fault. ZYPLC will coordinate return authorization and provide a replacement or repaired unit within the agreed lead time.
