Product Details

128987-130-01-CN Product Description

The Bently Nevada 128987-130-01-CN is a high-precision eddy current proximity probe engineered for the 3300 XL Monitoring System platform. Designed to operate at the intersection of physical machinery and digital intelligence, this probe serves as a critical data acquisition node within modern smart factory architectures. By delivering continuous, real-time shaft vibration and displacement data, the 128987-130-01-CN enables seamless integration across the full industrial data chain — from field-level sensing through protocol conversion, network transmission, SCADA visualization, and remote diagnostics.

In today's connected manufacturing environment, machinery health data must flow without interruption from rotating equipment to control rooms and cloud-based monitoring platforms. The 128987-130-01-CN is purpose-built to anchor this data flow, providing the raw signal fidelity that downstream systems depend on for accurate analysis and timely intervention.

The 128987-130-01-CN proximity probe operates as the primary sensing element within a layered industrial data architecture. Mounted adjacent to rotating shafts on turbines, compressors, pumps, or motors, the probe continuously measures gap voltage changes caused by shaft movement. This raw analog signal is transmitted through a matched Bently Nevada 330130 extension cable to a 3300 XL Proximitor Sensor (such as the 330180-X1-CN series), which conditions the signal into a calibrated output suitable for monitoring system input.

The conditioned signal feeds directly into the Bently Nevada 3300 XL rack-mounted monitor modules — including vibration monitors, thrust position monitors, and differential expansion monitors — where it is processed against user-defined alarm and danger setpoints. These monitors communicate with the plant's broader control infrastructure through dedicated communication interfaces. When paired with a Bently Nevada 3500/92 Communication Gateway or a third-party Modbus TCP / PROFIBUS DP gateway module, the vibration data becomes accessible to PLC controllers (such as Allen-Bradley ControlLogix or Siemens S7-400 series), DCS platforms, and SCADA systems running on Wonderware InTouch, Rockwell FactoryTalk View, or Inductive Automation Ignition.

At the network layer, industrial Ethernet switches — such as managed switches supporting PROFINET or EtherNet/IP — route the data packets from the monitoring rack to the plant historian and MES (Manufacturing Execution System). Edge computing gateways, including devices compatible with Bently Nevada System 1 Software, perform local data aggregation, trend analysis, and alarm pre-processing before forwarding structured datasets to cloud-based condition monitoring platforms or enterprise asset management (EAM) systems.

HMI panels installed at the machine skid level display real-time vibration trends, gap voltage readings, and alarm states sourced directly from the 3300 XL system. Operators can acknowledge alarms, review historical waveforms, and initiate remote diagnostic sessions without leaving the control room. When integrated with a Bently Nevada System 1 Evolution server, the 128987-130-01-CN's data contributes to machine-learning-driven predictive maintenance models that forecast bearing wear, rotor imbalance, and misalignment events weeks before they escalate to unplanned shutdowns.

For facilities operating mixed-protocol environments, the 128987-130-01-CN's analog output can be routed through a signal isolator / protocol converter module to bridge legacy 4–20 mA loops with modern OPC-UA data servers, ensuring backward compatibility with older DCS installations while enabling forward integration with Industry 4.0 platforms. Power for the proximitor and probe system is supplied by dedicated industrial DIN-rail power supplies (typically 24 VDC), ensuring stable, noise-free excitation voltage critical for accurate eddy current measurement.

Many industrial facilities face persistent challenges in achieving full machinery transparency: vibration data remains siloed within standalone monitoring racks, protocol mismatches prevent PLC and SCADA systems from accessing real-time machine health signals, and remote diagnostic capability is limited to on-site personnel with specialized equipment.

The 128987-130-01-CN addresses these gaps as the foundational sensing element of a connected monitoring strategy. By providing a reliable, high-fidelity analog signal that is fully compatible with the 3300 XL platform's communication gateways, it enables facilities to bridge the gap between physical machinery and digital monitoring infrastructure. Protocol unification is achieved through gateway modules that translate the 3300 XL's proprietary communication into standard industrial protocols — Modbus RTU, Modbus TCP, PROFIBUS DP, or OPC-UA — making vibration data universally accessible across the plant network.

Data island problems are eliminated when the 128987-130-01-CN's output is integrated into a plant-wide historian, allowing maintenance engineers to correlate vibration trends with process variables such as flow rate, temperature, and pressure. This cross-parameter visibility is essential for root cause analysis and for building accurate predictive maintenance models.

Remote monitoring and diagnostics become practical when the 3300 XL system is connected to a secure industrial VPN or remote access gateway. Maintenance teams can review real-time vibration spectra, acknowledge alarms, and adjust setpoints from any location, reducing the need for costly on-site visits and enabling 24/7 machine health oversight. Production line transparency is further enhanced through dashboard visualization tools that display KPIs such as overall vibration level (OA), 1X and 2X amplitude trends, and gap voltage stability — all derived from the 128987-130-01-CN's continuous signal output.

Alarm tracking and escalation workflows, configured within the SCADA or DCS platform, ensure that vibration exceedances trigger automated notifications to maintenance supervisors, log timestamped events for compliance reporting, and initiate pre-programmed protective actions such as machine trip or load reduction. System expansion is straightforward: additional 128987-130-01-CN probes can be added to monitor additional measurement planes on the same machine, or deployed on new equipment, with all signals consolidated within the existing 3300 XL rack infrastructure.

Q1: What communication protocols does the Bently Nevada 128987-130-01-CN support for SCADA and DCS integration?The 128987-130-01-CN outputs a standard analog signal (gap voltage / 4–20 mA equivalent via the 3300 XL proximitor). When connected to a Bently Nevada 3500/92 Communication Gateway or a compatible third-party gateway module, the data is made available over Modbus RTU, Modbus TCP, PROFIBUS DP, or OPC-UA, enabling direct integration with all major SCADA, DCS, and historian platforms. Communication latency is typically under 100 ms for standard Modbus polling cycles, suitable for real-time condition monitoring applications.

Q2: Is the 128987-130-01-CN compatible with non-Bently Nevada monitoring systems?The probe is optimized for use within the Bently Nevada 3300 XL ecosystem, including matched proximitor sensors and extension cables. However, its analog output signal can be interfaced with third-party vibration monitoring systems or signal conditioning modules that accept standard eddy current probe inputs, provided the driver circuit specifications are matched. For full protocol compatibility and system certification, use within the 3300 XL platform is recommended.

Q3: How does the 128987-130-01-CN support remote diagnostics and predictive maintenance?When integrated with Bently Nevada System 1 Condition Monitoring Software, the probe's continuous vibration data feeds machine learning algorithms that detect early-stage faults such as rotor imbalance, bearing wear, and shaft misalignment. Remote access to System 1 via secure VPN allows maintenance engineers to review waveform data, trend analysis, and alarm histories from any location, enabling proactive intervention before failures occur.

Q4: What warranty and pre-shipment testing does the 128987-130-01-CN include?Every 128987-130-01-CN unit supplied by NANKMOS is covered by a 12-month warranty and undergoes functional verification testing prior to shipment. Testing confirms probe sensitivity, cable integrity, and connector condition. In-stock units are available for fast global dispatch, with documentation packages available upon request for maintenance records and compliance purposes.
