Product Details

330709-000-070-10-02-00 Product Description

The Bently Nevada 330709-000-070-10-02-00 is a high-precision proximity probe engineered for the Bently Nevada 3300 XL Monitoring System, delivering reliable vibration and position signal acquisition at the field device layer of modern industrial data architectures. In smart factory environments where every microsecond of machine data matters, this probe serves as the critical sensing node that feeds real-time displacement and gap voltage signals into the broader automation data chain — from field-level signal conditioning through to SCADA dashboards and enterprise asset management platforms.

Designed for continuous operation in rotating machinery applications — including turbines, compressors, pumps, and motors — the 330709-000-070-10-02-00 integrates directly with the Bently Nevada 3300 XL proximitor/sensor system, providing conditioned output signals compatible with the 3300 XL monitor modules. These monitor modules, in turn, interface with plant-level DCS and PLC controllers via standard industrial communication protocols, enabling seamless data flow from the physical asset to the control room and beyond.

In a fully connected smart factory, the 330709-000-070-10-02-00 proximity probe anchors the signal acquisition layer. Mounted at the bearing housing of a critical rotating asset, it continuously measures shaft displacement and radial vibration, transmitting conditioned analog signals through a matched Bently Nevada 330130 extension cable to the Bently Nevada 3300 XL Proximitor. The proximitor converts the raw eddy-current signal into a calibrated voltage output, which feeds directly into the Bently Nevada 3300/16-Channel Monitor housed in the 3300 XL rack.

From the monitor rack, digitized vibration and position data is passed upstream via the system's communication backplane. Plant engineers configure the Bently Nevada System 1 Software — a condition monitoring and asset management platform — to aggregate data from multiple 3300 XL racks across the facility. System 1 communicates with the plant DCS (Distributed Control System), such as a Honeywell Experion PKS or Emerson DeltaV, using OPC-DA or OPC-UA data exchange, ensuring that vibration alarm states and trend data are visible on the main control room HMI in real time.

Simultaneously, the 3300 XL system's relay outputs connect to the plant's Siemens S7-300 PLC or Allen-Bradley ControlLogix safety interlock logic, enabling automatic machine trip on high-vibration alarm conditions. The PLC communicates over PROFIBUS DP or EtherNet/IP to the plant SCADA server, where operators monitor all rotating equipment health on a unified dashboard. Edge gateway devices — such as the Moxa MGate MB3480 or similar industrial protocol converters — can bridge legacy MODBUS RTU signals from older 3300 XL installations into modern Ethernet-based SCADA architectures, eliminating data silos between legacy and new-generation monitoring systems.

For remote sites or unmanned substations, the data chain extends further: the SCADA server pushes alarm notifications and trend reports to cloud-based asset management platforms via secure VPN tunnels, enabling remote diagnostics by reliability engineers without requiring on-site presence. The Bently Nevada TDXnet remote data acquisition module can supplement this architecture by providing direct Ethernet connectivity from the 3300 XL rack to the plant LAN, supporting real-time data streaming to historian servers such as OSIsoft PI for long-term trend analysis and predictive maintenance modeling.

Many industrial facilities operate with fragmented monitoring architectures — proximity probes wired to standalone monitors with no digital integration, vibration data trapped in proprietary formats, and alarm events that never reach the SCADA or ERP layer. The Bently Nevada 330709-000-070-10-02-00, deployed within the 3300 XL ecosystem, directly addresses these data gaps:

Q1: What communication protocols does the Bently Nevada 3300 XL system support for SCADA integration? The 3300 XL monitor system supports OPC-DA and OPC-UA data exchange via System 1 Software, MODBUS RTU through compatible gateway modules, and hard-wired relay outputs for PLC interlock integration. This multi-protocol architecture ensures compatibility with Honeywell, Emerson, Siemens, and Rockwell SCADA and DCS platforms without requiring custom protocol converters in most installations.

Q2: How does the 330709-000-070-10-02-00 perform in high-EMI industrial environments, and does interference affect network data quality? The 330709-000-070-10-02-00 uses eddy-current sensing technology, which is inherently immune to contamination from oil, dust, and moderate EMI. The coaxial cable assembly and shielded extension cable minimize signal noise before digitization at the monitor module. Once digitized within the 3300 XL rack, data transmission to SCADA and DCS systems is handled over shielded industrial Ethernet or PROFIBUS DP, maintaining signal integrity across the full data chain.

Q3: Can the 330709-000-070-10-02-00 be integrated into an existing plant network without replacing the current SCADA or DCS infrastructure? Yes. The 3300 XL system is designed for non-disruptive integration. OPC-UA connectivity allows System 1 Software to publish vibration data to any OPC-compliant SCADA or DCS historian without modifying existing control logic. For legacy MODBUS-based systems, industrial protocol gateways bridge the communication gap, enabling the probe's data to appear as standard register values within the existing SCADA tag database.

Q4: What warranty and pre-shipment testing does the 330709-000-070-10-02-00 carry? Every Bently Nevada 330709-000-070-10-02-00 supplied by NANKMOS carries a 12-Month Warranty covering manufacturing defects and functional performance. Each unit undergoes functional verification and output signal testing prior to shipment, ensuring that the probe meets Bently Nevada's original specification for gap voltage output, frequency response, and sensitivity before it reaches your facility.
