Product Details

21000-16-10-00-067-04-02 Product Description

The Bently Nevada 21000-16-10-00-067-04-02 is a high-precision proximity probe engineered for the Bently Nevada 3300 Series vibration monitoring platform. Designed for continuous operation in demanding industrial environments, this probe serves as a critical sensing node within the smart factory data chain — capturing real-time shaft displacement, radial vibration, and axial position signals from rotating machinery and feeding that data upstream through a fully integrated industrial communication architecture.

In modern smart manufacturing facilities, the integrity of the data link between field-level sensors and supervisory control systems determines the reliability of every downstream decision. The 21000-16-10-00-067-04-02 is built to anchor that link at the signal acquisition layer, delivering consistent, low-latency analog output that integrates seamlessly with the Bently Nevada 3300/16 XY Proximity Transducer System and its associated signal conditioning modules. From the probe tip to the control room, every measurement passes through a validated signal path designed for industrial-grade accuracy.

The 21000-16-10-00-067-04-02 proximity probe operates as the first node in a multi-layer industrial data acquisition chain. Installed at the bearing housing or shaft journal of a turbine, compressor, pump, or motor, the probe generates a continuous analog voltage signal proportional to the gap between the probe tip and the target surface. This signal travels through a matched Bently Nevada 3300/05 Extension Cable to a Bently Nevada 3300/50 Proximitor Sensor, which conditions and amplifies the raw eddy-current signal into a calibrated output suitable for monitor input.

The conditioned signal enters a Bently Nevada 3300/16 XY Proximity Monitor or a compatible 3500 Series Rack Monitor, where it is processed against configurable alarm setpoints for Alert and Danger thresholds. The monitor's relay outputs and 4–20 mA analog retransmission channels connect directly to a Siemens S7-300 PLC or Allen-Bradley ControlLogix controller via hardwired I/O or through a Modbus RTU to Ethernet gateway, enabling the vibration data to be absorbed into the plant-wide control logic.

At the network layer, a Moxa NPort 5150 Serial-to-Ethernet Device Server or an HMS Anybus Communicator gateway bridges the serial Modbus RTU output of the 3300 Series monitor to an Ethernet/IP or PROFINET backbone, making the vibration data available to a Wonderware InTouch SCADA or Ignition by Inductive Automation supervisory platform. Operators at the control room HMI — such as a Siemens TP1200 Comfort Panel — can view real-time shaft orbit plots, trend data, and alarm states without leaving the workstation.

For facilities deploying edge computing architectures, the vibration data stream from the 21000-16-10-00-067-04-02 can be routed through an industrial edge gateway running OPC-UA server software, publishing structured data objects to cloud-based analytics platforms or on-premise historian databases such as OSIsoft PI System. This enables long-term trend analysis, predictive maintenance modeling, and cross-asset correlation — all driven by the raw signal that originates at this single proximity probe.

Power to the monitoring rack is supplied by a Bently Nevada 3300/20 Power Supply or an equivalent 24 VDC DIN-rail industrial power supply, ensuring stable, noise-free excitation for the entire signal chain. The complete system — from probe to SCADA dashboard — is designed for continuous, uninterrupted operation in environments subject to high temperature, vibration, electromagnetic interference, and process fluid exposure.

Many industrial facilities operate with fragmented monitoring architectures where vibration data from rotating machinery never reaches the SCADA or MES layer in a structured, actionable format. The Bently Nevada 21000-16-10-00-067-04-02 addresses this gap by providing a reliable, calibrated signal source that is fully compatible with the 3300 Series monitoring ecosystem — a platform widely supported by protocol gateways, DCS interfaces, and SCADA drivers across the industry.

Protocol fragmentation is one of the most common barriers to plant-wide data visibility. When vibration monitors speak only analog or serial Modbus while the plant backbone runs PROFINET or EtherNet/IP, data islands form and maintenance teams lose real-time insight into machine health. By pairing the 21000-16-10-00-067-04-02 with a compatible protocol gateway, engineers can bridge this gap without replacing existing infrastructure.

Remote diagnostics become possible once the vibration signal is on the network. Maintenance engineers can access live shaft displacement trends, compare current readings against historical baselines, and receive alarm notifications via email or SMS — all without entering the machine room. This capability is especially valuable for unmanned substations, offshore platforms, and remote pumping stations where on-site response time is measured in hours, not minutes.

Production line transparency improves when every critical machine has a validated sensor feeding real-time data to the SCADA historian. With the 21000-16-10-00-067-04-02 installed and integrated, maintenance planners can schedule interventions based on actual machine condition rather than fixed time intervals, reducing unplanned downtime and extending equipment service life.

Alarm management and traceability are strengthened when vibration events are time-stamped and logged in the SCADA historian alongside process variables such as flow rate, pressure, and temperature. Cross-referencing vibration spikes with process upsets enables root-cause analysis that would be impossible with standalone, unnetworked monitoring equipment.

Q1: What communication protocols are compatible with the Bently Nevada 21000-16-10-00-067-04-02 monitoring system?The 21000-16-10-00-067-04-02 probe outputs an analog signal to the 3300 Series monitor. The monitor's serial and relay outputs support Modbus RTU integration. With an appropriate protocol gateway (e.g., Modbus RTU to EtherNet/IP, PROFINET, or OPC-UA), the vibration data can be delivered to any modern DCS, PLC, or SCADA platform. All units are tested for signal integrity prior to shipment.

Q2: How is network stability maintained in high-vibration or electrically noisy environments?The 3300 Series signal chain — including the 21000-16-10-00-067-04-02 probe, extension cable, and Proximitor sensor — is designed with shielded coaxial construction to reject electromagnetic interference. At the network layer, industrial-grade Ethernet switches with EMI-hardened enclosures and redundant ring topologies (e.g., PROFINET MRP or EtherNet/IP DLR) ensure continuous data transmission even in the presence of motor drives, welding equipment, and high-voltage switchgear.

Q3: Can this probe be integrated into an existing SCADA or HMI system without replacing the current PLC infrastructure?Yes. The 3300 Series monitor provides analog retransmission outputs (4–20 mA) and relay contacts that connect directly to existing PLC analog input cards. For digital integration, a Modbus RTU gateway maps the monitor's data registers to the PLC's communication interface. No changes to the existing PLC program structure are required for basic alarm and trend integration.

Q4: What does the 12-month warranty cover, and how is remote diagnostics support provided?All Bently Nevada 21000-16-10-00-067-04-02 units supplied by NANKMOS carry a 12-month warranty covering manufacturing defects and signal performance. Each unit undergoes pre-shipment functional testing to verify output linearity and sensitivity. Remote diagnostics support is available via email and phone for installation guidance, signal calibration, and system integration troubleshooting throughout the warranty period.
