Product Details

24701-33-05-00-025-04-02 Product Description

The Bently Nevada 24701-33-05-00-025-04-02 is a high-precision proximity probe engineered for the 3300 Series vibration monitoring platform, delivering continuous, real-time shaft displacement and position data across the full industrial data chain. In smart factory environments where machine health directly impacts production uptime, this probe serves as the critical sensing node that feeds live mechanical signals into PLC controllers, SCADA systems, HMI dashboards, and edge gateways — enabling predictive maintenance, remote diagnostics, and automated alarm response without manual intervention.

Designed for rotating machinery protection in turbines, compressors, pumps, and generators, the 24701-33-05-00-025-04-02 integrates seamlessly into the Bently Nevada 3300 Series ecosystem, working in tandem with the 3300/16 proximitor sensor and 3300/55 monitor modules to deliver conditioned analog output signals that are protocol-compatible with Modbus RTU, PROFIBUS DP, and 4–20 mA transmission standards. This makes it directly connectable to distributed control systems (DCS), remote I/O racks, and industrial Ethernet backbones without signal conversion loss.

In a fully connected smart factory, the Bently Nevada 24701-33-05-00-025-04-02 proximity probe anchors the signal acquisition layer. Mounted at the bearing journal of a high-speed rotating machine, it continuously measures radial shaft displacement and transmits conditioned analog signals through the Bently Nevada 3300/16 Proximitor Sensor to the 3300/55 Vibration Monitor, where raw displacement data is converted into engineering units and made available for downstream network consumption.

From the monitor output, the signal enters the plant's control backbone. A Siemens S7-300 PLC or Allen-Bradley ControlLogix controller reads the 4–20 mA analog channel via a remote I/O module — such as the Beckhoff EL3174 analog input terminal — and maps the vibration value into the process data object (PDO) for real-time logic evaluation. If shaft displacement exceeds the programmed danger threshold, the PLC triggers an automated shutdown relay and simultaneously pushes an alarm event to the Wonderware InTouch HMI or Ignition SCADA platform over an industrial Ethernet (PROFINET or EtherNet/IP) backbone.

At the network layer, an industrial managed Ethernet switch — such as the Moxa EDS-510A — provides ring-topology redundancy, ensuring that vibration data packets from the 3300 Series monitor reach the SCADA server without interruption even during a single link failure. The SCADA system aggregates vibration trends, orbit plots, and alarm histories from multiple 24701-series probes across the plant, feeding a PI System historian or OSIsoft data archive for long-term asset health trending and regulatory compliance reporting.

For remote diagnostics, an edge gateway — such as the Advantech WISE-5231 — collects the Modbus RTU data stream from the 3300/55 monitor and publishes it via MQTT to a cloud-based condition monitoring platform, enabling maintenance engineers to review shaft centerline plots, spectral data, and alarm logs from any location without being on-site. This remote visibility is especially critical for unmanned substations, offshore platforms, and multi-site industrial operations where travel-based inspection is cost-prohibitive.

Power to the sensing chain is supplied through a Phoenix Contact QUINT industrial power supply, which provides stable 24 VDC to the proximitor and monitor modules, ensuring measurement accuracy is not compromised by voltage fluctuation. The complete data chain — from probe tip to cloud dashboard — is validated during factory acceptance testing (FAT) and pre-shipment functional verification, confirming that every 24701-33-05-00-025-04-02 unit shipped from NANKMOS inventory is operationally ready for immediate installation.

Many industrial facilities operating legacy rotating machinery face a common set of connectivity challenges: vibration sensors that output analog signals incompatible with modern Ethernet-based SCADA architectures, monitoring systems that operate as isolated data islands with no integration into the plant DCS, and maintenance teams that rely on periodic manual rounds rather than continuous automated surveillance.

The Bently Nevada 24701-33-05-00-025-04-02 addresses these gaps directly. Its eddy-current sensing technology provides non-contact, high-bandwidth displacement measurement that is immune to oil contamination and mechanical wear — eliminating the signal degradation that plagues contact-type sensors in harsh environments. When paired with the 3300 Series monitor and a protocol gateway module, the analog output is bridged to Modbus TCP or PROFIBUS DP, resolving the protocol mismatch between legacy field instruments and modern industrial Ethernet networks.

For production line transparency, the probe's continuous data stream enables real-time orbit and trend displays on the plant HMI, replacing the guesswork of periodic vibration checks with a live, quantitative picture of machine health. Alarm setpoints are configurable at the monitor level, ensuring that alert and danger thresholds are enforced automatically — reducing the risk of catastrophic bearing failure and unplanned downtime. Historical alarm data is logged to the SCADA historian, providing the audit trail required for root-cause analysis and insurance documentation.

System expansion is straightforward: additional 24701-series probes can be added to the 3300 Series rack without rewiring the control network, and the monitor's analog outputs can be mapped to additional PLC channels or remote I/O nodes as the monitoring scope grows. This scalability makes the 24701-33-05-00-025-04-02 a long-term investment in plant connectivity infrastructure rather than a single-point sensor replacement.

Q1: What communication protocols does the Bently Nevada 24701-33-05-00-025-04-02 support for SCADA integration?The proximity probe outputs a conditioned analog signal (4–20 mA or voltage) through the 3300/16 Proximitor and 3300/55 Monitor. The monitor's analog output is compatible with Modbus RTU and PROFIBUS DP via appropriate gateway modules, enabling direct integration with SCADA platforms such as Ignition, Wonderware, and FactoryTalk without additional signal conditioning hardware.

Q2: How does the 3300 Series system ensure network stability and data continuity in a plant environment?The 3300 Series architecture uses hardwired analog signal transmission from probe to proximitor to monitor, which is inherently immune to network packet loss or Ethernet congestion. Digital data is only introduced at the monitor output stage, where industrial managed switches with ring-topology redundancy (e.g., PROFINET MRP or EtherNet/IP DLR) ensure that upstream SCADA and historian systems receive uninterrupted data streams.

Q3: Can the 24701-33-05-00-025-04-02 be used for remote diagnostics and predictive maintenance?Yes. When the 3300/55 monitor's Modbus RTU output is connected to an edge gateway (such as the Advantech WISE-5231 or similar IIoT device), vibration data — including shaft displacement, gap voltage, and alarm status — can be published to cloud-based condition monitoring platforms via MQTT or OPC-UA. This enables remote trend analysis, alarm notification, and predictive maintenance scheduling without on-site presence.

Q4: What quality assurance and warranty coverage does NANKMOS provide for this product?Every Bently Nevada 24701-33-05-00-025-04-02 unit supplied by NANKMOS undergoes pre-shipment functional testing to verify probe sensitivity, cable integrity, and connector continuity. All units are covered by a 12-month warranty against manufacturing defects. In-stock units are available for immediate dispatch, and our technical team can provide installation guidance, protocol configuration support, and system integration consultation upon request.
