Product Details

21000-28-10-00-167-04-02 Product Description

The Bently Nevada 21000-28-10-00-167-04-02 is a precision proximity probe engineered for the Bently Nevada 3300 Series vibration monitoring platform. In modern smart factory environments, this probe serves as the critical front-end sensing node in a continuous data chain that spans from rotating machinery to enterprise-level SCADA dashboards. Its eddy-current sensing principle delivers non-contact, real-time shaft displacement and vibration data with exceptional repeatability — forming the foundation of any reliable condition monitoring and predictive maintenance architecture.

At the field level, the 21000-28-10-00-167-04-02 interfaces directly with the Bently Nevada 3300/16 proximitor sensor, converting raw mechanical motion into a calibrated voltage signal. This signal is then routed into the 3500 Series rack-based monitoring system, where dedicated I/O modules digitize and process the data stream. From the 3500 rack, the conditioned vibration data is transmitted via Modbus RTU or Modbus TCP/IP to plant-level PLCs — such as Allen-Bradley ControlLogix or Siemens S7-300 controllers — enabling closed-loop protection logic and automated shutdown sequences without operator intervention.

The data flow does not stop at the PLC layer. In a fully connected smart factory, the processed vibration signals are forwarded through industrial Ethernet switches — such as those in the Hirschmann MICE or Phoenix Contact FL SWITCH series — to edge gateways and protocol converters. These gateways, including units compatible with the Bently Nevada System 1 software platform, translate proprietary monitoring data into OPC-UA or MQTT streams suitable for cloud-based analytics and digital twin applications. This protocol conversion step is essential for eliminating data silos between legacy vibration monitoring systems and modern IIoT infrastructure.

At the SCADA and HMI layer, operators gain full visibility into shaft vibration trends, gap voltage readings, and alarm states through platforms such as GE iFIX, Wonderware InTouch, or Ignition by Inductive Automation. The 21000-28-10-00-167-04-02 probe's signal, once digitized and transmitted, populates real-time trend displays, historical data logs, and alarm management panels — enabling maintenance teams to detect bearing wear, rotor imbalance, and misalignment weeks before a failure event occurs. Integration with remote I/O modules, such as those in the Bently Nevada TDI (Transient Data Interface) family, further extends the monitoring reach across geographically distributed assets.

For facilities operating variable-speed drives and frequency inverters — such as ABB ACS880 or Siemens SINAMICS series — the vibration data captured by the 21000-28-10-00-167-04-02 can be correlated with drive speed feedback to identify resonance conditions and optimize operational speed ranges. This cross-system data correlation, enabled by the seamless network integration of the 3300/3500 monitoring platform, is a hallmark of Industry 4.0 connectivity and represents the true value of deploying a properly networked proximity probe system.

Remote diagnostics capabilities are equally significant. Through the Bently Nevada System 1 software or compatible third-party CMMS platforms, maintenance engineers can remotely access gap voltage readings, dynamic vibration waveforms, and alarm histories for the 21000-28-10-00-167-04-02 installation without requiring physical access to the machine train. This capability dramatically reduces mean time to diagnosis (MTTD) and supports predictive maintenance scheduling across multi-site operations.

Every unit of the Bently Nevada 21000-28-10-00-167-04-02 supplied by NANKMOS undergoes pre-shipment functional verification, including output voltage linearity checks and cable continuity testing, ensuring that the probe arrives ready for immediate installation and commissioning. Stock availability is maintained to support urgent MRO requirements, and all units are covered by a 12-month warranty against manufacturing defects.

The complete data chain anchored by the Bently Nevada 21000-28-10-00-167-04-02 begins at the machine surface. The probe tip, positioned within 2.0 mm of the rotating shaft, generates a continuous gap voltage signal that reflects instantaneous shaft position and vibration amplitude. This raw analog signal travels through the matched extension cable to the Bently Nevada 3300/16 Proximitor sensor, which conditions and amplifies the signal before passing it to the 3500/42M Proximitor I/O module housed in the 3500 rack system.

Within the 3500 rack, the 3500/20 Rack Interface Module manages communication between the monitoring hardware and the plant network. Using Modbus TCP/IP, the rack transmits real-time vibration vectors, gap voltages, and alarm states to the site PLC — typically an Allen-Bradley ControlLogix L7x or Siemens S7-400 — where the data is used to trigger automated protective actions such as turbine trip or pump isolation. Simultaneously, the 3500/92 Communication Gateway Module provides a dedicated OPC-DA/OPC-UA server interface, allowing SCADA systems to subscribe to live data tags without burdening the PLC with additional polling overhead.

At the network transport layer, managed industrial Ethernet switches — such as the Hirschmann MICE3-8TX-EEC or Phoenix Contact FL SWITCH 2008 — provide the deterministic, low-latency backbone required for real-time vibration data transmission. These switches support PROFINET and EtherNet/IP traffic segmentation, ensuring that vibration monitoring data streams remain isolated from general plant IT traffic and maintain sub-millisecond update rates.

Edge computing nodes, such as the Moxa UC-8112-LX industrial computer or a compatible IIoT gateway, aggregate data from multiple 3500 racks and apply local analytics — including FFT spectrum analysis and alarm correlation — before forwarding compressed data packets to cloud platforms or enterprise historians via MQTT over secure TLS connections. This edge processing layer is critical for bandwidth management in facilities with dozens of monitored machine trains.

At the visualization layer, operators interact with vibration data through Bently Nevada System 1 software, which provides full waveform analysis, orbit plots, and trend displays for the 21000-28-10-00-167-04-02 probe outputs. For facilities using broader SCADA platforms, Ignition by Inductive Automation or Wonderware System Platform can consume the OPC-UA data feed to display vibration KPIs alongside process variables such as temperature, flow, and pressure — delivering the unified operational picture that defines a true smart factory.

Industrial facilities frequently encounter four categories of connectivity challenges that the Bently Nevada 21000-28-10-00-167-04-02 deployment — when properly integrated — directly addresses:

Protocol Fragmentation: Many plants operate a mix of legacy 4–20 mA vibration transmitters alongside modern digital monitoring systems. The 3500 rack's built-in Modbus and OPC-UA gateway capabilities eliminate the need for standalone protocol converters, allowing the 21000-28-10-00-167-04-02 signal to be consumed by any modern PLC or SCADA system without additional hardware investment.

Data Silos and Visibility Gaps: Vibration data trapped within a standalone monitoring system provides limited value. By routing the 21000-28-10-00-167-04-02 data through the plant network to SCADA and historian platforms, maintenance teams gain the ability to correlate vibration trends with process upsets, load changes, and maintenance events — transforming isolated sensor readings into actionable machine health intelligence.

Remote Monitoring Limitations: For unmanned substations, offshore platforms, or remote pump stations, the ability to remotely access vibration waveforms and alarm histories is operationally critical. The OPC-UA and MQTT connectivity of the 3500 platform enables secure remote diagnostics for the 21000-28-10-00-167-04-02 installation from any authorized workstation or mobile device, reducing the need for costly site visits.

System Scalability: As production capacity expands, additional 21000-28-10-00-167-04-02 probes and 3500 rack modules can be added to the monitoring network without architectural changes. The standardized Modbus and OPC-UA interfaces ensure that new monitoring points integrate seamlessly into existing SCADA and historian configurations, protecting the initial network investment.
