Product Details

21000-28-05-35-028-00-02 Product Description

The Bently Nevada 21000-28-05-35-028-00-02 is a high-precision eddy-current 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 complete industrial data chain — converting mechanical shaft displacement and vibration signals into reliable analog outputs that feed directly into condition monitoring systems, SCADA platforms, and predictive maintenance networks. With verified stock availability, pre-shipment functional testing, and a 12-month warranty, the 21000-28-05-35-028-00-02 is a trusted component for plant engineers and automation integrators worldwide.

In a fully connected smart factory, the Bently Nevada 21000-28-05-35-028-00-02 proximity probe sits at the very beginning of the industrial data chain. Mounted on rotating machinery — compressors, turbines, pumps, and motors — it continuously measures shaft radial vibration and gap voltage, transmitting analog signals through matched Bently Nevada extension cables to a Bently Nevada 3300 XL Proximitor Sensor. The proximitor converts the raw eddy-current signal into a conditioned voltage output, which is then routed into a Bently Nevada 3500/42M Proximitor/Seismic Monitor rack module for real-time signal processing, alarm threshold evaluation, and trip relay activation.

From the 3500 Series monitor rack, digitized vibration data is transmitted over Modbus TCP or OPC-UA to plant-level SCADA systems — such as GE iFIX, Wonderware AVEVA, or Rockwell FactoryTalk — where operators visualize shaft orbits, trend plots, and alarm histories on HMI screens. Simultaneously, the data stream feeds into a Bently Nevada System 1 Condition Monitoring Software server, enabling predictive analytics, bearing wear trending, and remote diagnostics accessible from any networked workstation or mobile device.

For facilities integrating legacy equipment, a Moxa MGate MB3480 Modbus-to-Ethernet gateway bridges the 3500 Series serial output to the plant Ethernet backbone, ensuring seamless data flow into modern DCS platforms such as Emerson DeltaV or Honeywell Experion. Where network segmentation is required, an industrial managed Ethernet switch — such as the Hirschmann RS20 or Moxa EDS-408A — provides VLAN isolation between the vibration monitoring subnet and the broader plant network, protecting data integrity and reducing latency.

At the edge, an edge computing gateway (e.g., Advantech ECU-1251 or Siemens SIMATIC IPC) can aggregate vibration data from multiple 3500 Series racks, apply local analytics algorithms, and push compressed datasets upstream to cloud-based asset management platforms. This architecture supports the full IIoT data loop: from the 21000-28-05-35-028-00-02 probe tip sensing micron-level shaft movement, through protocol conversion, network transmission, SCADA visualization, and finally to remote diagnostic dashboards — all without interrupting machine operation.

Power for the monitoring infrastructure is supplied by industrial DIN-rail power supplies (e.g., Phoenix Contact QUINT series or Bently Nevada 3500/15 Power Supply module), ensuring stable 24 VDC delivery to the proximitor sensors and monitor racks even during grid fluctuations. For facilities requiring wireless data backhaul from remote machinery, an industrial wireless access point supporting IEEE 802.11ac or WirelessHART can extend the monitoring network to areas where cabling is impractical, with the 3500 Series monitor acting as the local data concentrator.

Protocol Fragmentation: Many plants operate a mix of legacy serial-based vibration monitors alongside modern Ethernet-enabled DCS platforms. The 3300/3500 Series ecosystem — anchored by the 21000-28-05-35-028-00-02 probe — supports protocol bridging through Modbus RTU, Modbus TCP, and OPC-UA, eliminating the need for custom middleware and reducing integration engineering hours.

Data Silos: Vibration data trapped in standalone condition monitoring systems cannot contribute to plant-wide predictive maintenance programs. By connecting the 3500 Series monitor to SCADA historians via OPC-UA, all vibration trends, alarm events, and trip records become available to enterprise asset management (EAM) systems, breaking down data silos and enabling cross-asset correlation analysis.

Remote Monitoring Gaps: For unmanned or remote installations, the 3500 Series network output — combined with a cellular or fiber-connected edge gateway — enables 24/7 remote vibration monitoring. Alarm notifications are pushed via email, SMS, or SCADA pop-up to on-call engineers, reducing response time and preventing unplanned downtime.

Production Line Transparency: Integrating proximity probe data into MES (Manufacturing Execution Systems) provides real-time machine health context alongside production KPIs. Operators can correlate vibration spikes with specific production batches, shift changes, or load variations, enabling root-cause analysis without physical inspection.

Alarm Tracking and Audit: The 3500 Series monitor logs all alarm and trip events with timestamps, which are forwarded to SCADA and historian systems for regulatory compliance reporting and maintenance audit trails. This ensures full traceability from the 21000-28-05-35-028-00-02 sensor signal to the maintenance work order.

System Scalability: The modular 3500 Series rack architecture allows plants to start with a single proximitor channel and expand to full 16-channel vibration, temperature, and process variable monitoring without replacing existing probes or cabling — protecting the investment in 21000-28-05-35-028-00-02 probes already installed in the field.

Q1: What communication protocols does the Bently Nevada 3300/3500 Series support for SCADA integration? The 3500 Series monitors support Modbus RTU (RS-232/RS-485), Modbus TCP/IP, and OPC-UA natively. With an external protocol gateway such as the Moxa MGate series, the system can also interface with PROFIBUS DP, EtherNet/IP, and DNP3 networks. The 21000-28-05-35-028-00-02 probe itself outputs an analog signal; protocol conversion occurs at the monitor rack level, ensuring compatibility with virtually any plant SCADA or DCS platform.

Q2: How is network stability and data latency managed in high-vibration industrial environments? The 3500 Series monitor processes proximity probe signals locally at the rack level, with alarm and trip decisions made in under 20 milliseconds — independent of network availability. SCADA data transmission occurs on a separate communication channel, so network latency or interruptions do not affect machine protection functions. Industrial managed switches with QoS (Quality of Service) prioritization further ensure that vibration data packets receive network priority over lower-criticality traffic.

Q3: Can the 21000-28-05-35-028-00-02 probe be used for remote diagnostics and predictive maintenance? Yes. When connected to a 3500 Series monitor with OPC-UA or Modbus TCP output, vibration data from the 21000-28-05-35-028-00-02 probe can be streamed continuously to Bently Nevada System 1 software or third-party predictive maintenance platforms. Remote engineers can access real-time shaft orbits, spectrum data, and alarm histories from any networked location, enabling condition-based maintenance scheduling without on-site visits.

Q4: What warranty and pre-shipment testing does NANKMOS provide for the 21000-28-05-35-028-00-02? All Bently Nevada 21000-28-05-35-028-00-02 units supplied by NANKMOS undergo pre-shipment functional verification, including gap voltage output testing and cable continuity checks, before dispatch. Each unit is covered by a 12-month warranty against manufacturing defects and functional failure. In-stock units are available for same-week shipment globally.
