Product Details

330709-000-130-10-02-00 Product Description

The Bently Nevada 330709-000-130-10-02-00 is a precision eddy-current proximity probe engineered for seamless integration within the 3300 XL Series machinery protection and condition monitoring architecture. Designed to deliver continuous, non-contact radial vibration and position measurement, this probe serves as the primary sensing element in a layered industrial control system where signal fidelity, mechanical reliability, and long-term diagnostic consistency are non-negotiable requirements.

Within a complete 3300 XL monitoring architecture, the 330709-000-130-10-02-00 operates as the field-level sensing node, transmitting high-resolution displacement signals to the 3300 XL proximitor/driver module — typically the Bently Nevada 330180 or 330130 series — which conditions and converts the raw eddy-current signal into a calibrated voltage output readable by the 3500 Series rack-based monitoring system. This signal chain forms the foundation of the vibration monitoring layer, feeding real-time data to the 3500/42M Proximitor I/O Module and ultimately to the 3500/92 Communication Gateway for integration with DCS platforms such as Emerson DeltaV, Honeywell Experion, or ABB System 800xA.

The probe's 130 mm armored extension cable and standardized 10-32 UNF connector interface ensure mechanical compatibility with existing 3300 XL probe holders and field junction boxes, reducing installation time and eliminating the need for custom cable fabrication. Its 7.87 mm (5/8-18 UNF) threaded body allows direct mounting into standard proximity probe brackets used across rotating machinery including steam turbines, gas compressors, centrifugal pumps, and large induction motors.

From a system architecture perspective, the 330709-000-130-10-02-00 contributes to multiple control layers simultaneously. At the sensing layer, it provides the raw displacement signal. At the protection layer, its output drives the 3500 Series trip multiplexer logic, enabling automatic machine shutdown upon exceeding vibration thresholds. At the diagnostic layer, the continuous waveform data supports Bently Nevada System 1 software for trend analysis, orbit plots, and predictive maintenance scheduling. At the communication layer, the conditioned signal integrates with MODBUS RTU or OPC-UA interfaces via the 3500/92 gateway, enabling plant-wide SCADA visibility.

For installations requiring redundant vibration monitoring, the 330709-000-130-10-02-00 can be deployed in dual-probe configurations alongside a second probe offset at 90 degrees, feeding independent channels of the 3500/42M module to generate full shaft orbit data. This redundancy architecture is critical in API 670-compliant installations where single-point-of-failure protection is mandatory for high-value rotating assets.

The probe is factory-calibrated for use with Bently Nevada standard extension cables and proximitor drivers within the 3300 XL system, ensuring the linear range, sensitivity (200 mV/mil nominal), and gap voltage specifications are pre-validated before shipment. Each unit undergoes functional verification testing covering output linearity, frequency response, and insulation resistance prior to dispatch, supporting rapid commissioning and minimizing field calibration effort.

Inventory is maintained in-stock for immediate dispatch, supporting both planned maintenance outages and emergency replacement scenarios. All units are supplied with a 12-Month Warranty covering manufacturing defects and performance conformance to Bently Nevada 3300 XL system specifications.

The 330709-000-130-10-02-00 proximity probe is designed to function as a precision input node within a fully integrated Bently Nevada and broader plant automation ecosystem. In a typical turbomachinery protection architecture, the probe pairs directly with the Bently Nevada 330180-51-05 Proximitor Sensor to form a complete probe-driver assembly, with the proximitor mounted in the field junction box and the conditioned output routed to the 3500/42M Proximitor I/O Module housed in the 3500 Series rack.

The 3500 rack system — anchored by the 3500/15 Power Supply Module and managed by the 3500/22M Transient Data Interface — provides the centralized processing backbone for all vibration, position, and dynamic pressure channels. The 3500/92 Communication Gateway Module bridges the protection system to the plant DCS or SCADA layer, enabling real-time alarm and trip status transmission via MODBUS TCP or OPC-UA protocols.

For installations requiring expanded I/O capacity, the 3500/40M Proximitor I/O Module can be added to the same rack to accommodate additional probe channels without architectural redesign. In parallel, Bently Nevada System 1 Condition Monitoring Software aggregates waveform data from all probe channels, enabling orbit analysis, spectrum trending, and predictive maintenance workflows that reduce unplanned downtime across the asset fleet.

At the plant network layer, an industrial managed Ethernet switch (e.g., Hirschmann RS20 or Cisco IE3400) connects the 3500 gateway to the historian and DCS servers, ensuring deterministic data delivery with VLAN segmentation for cybersecurity compliance. Power distribution to the field junction boxes is typically managed through a 24 VDC DIN-rail power supply with redundant feed capability, maintaining probe excitation voltage stability across the full operating temperature range.

The 330709-000-130-10-02-00 proximity probe is deployed across a broad spectrum of heavy industrial applications where continuous shaft monitoring is critical to process safety and asset longevity.

In power generation, the probe monitors radial shaft vibration on steam turbine rotors and generator shafts, providing the primary trip signal to the turbine protection system. In oil and gas processing, it is installed on centrifugal compressor trains and pipeline booster pumps, where API 670 compliance mandates continuous vibration monitoring with automatic shutdown capability. In petrochemical and refinery environments, the probe supports condition monitoring on reactor feed pumps and cracked gas compressors operating in high-temperature, corrosive atmospheres.

In water and wastewater treatment, large vertical turbine pumps and blower trains utilize the 3300 XL probe system for bearing wear detection and imbalance trending. In mining and mineral processing, the probe is applied to SAG mill pinion bearings and slurry pump shafts, where early vibration detection prevents catastrophic bearing failures that would halt production. In marine and offshore applications, the probe monitors main propulsion shaft alignment and auxiliary machinery on FPSOs and LNG carriers, where redundant monitoring architecture is required by classification society rules.

Across all these applications, the 330709-000-130-10-02-00 delivers consistent signal quality, mechanical durability, and system compatibility that supports both real-time protection and long-term predictive maintenance programs.

Q1: Is the 330709-000-130-10-02-00 directly compatible with the Bently Nevada 3500 Series rack system without additional signal conditioning?A: The 330709-000-130-10-02-00 requires a compatible Bently Nevada proximitor/driver — such as the 330180 or 330130 series — to condition the eddy-current signal before it enters the 3500/42M I/O module. The probe itself does not connect directly to the rack; the probe-driver assembly forms the complete sensing chain. Ensure the extension cable length and proximitor driver are matched to the 330709 series specifications for correct linear range and sensitivity calibration.

Q2: Can this probe be used in a redundant dual-probe configuration for API 670 compliance?A: Yes. The 330709-000-130-10-02-00 is fully compatible with dual-probe radial vibration configurations as required by API 670. Two probes are installed at 90-degree offsets (X and Y planes) on the same bearing journal, each connected to independent channels of the 3500/42M module. This configuration generates full shaft orbit data and provides single-channel fault tolerance, ensuring the protection system remains operational if one probe or cable develops a fault. The 3500 rack's channel-pair logic supports automatic alarm and trip processing from either or both channels independently.

Q3: What is the warranty coverage and what does the 12-Month Warranty include for this proximity probe?A: All 330709-000-130-10-02-00 units supplied by NANKMOS are covered by a 12-Month Warranty from the date of shipment. The warranty covers manufacturing defects, performance non-conformance to Bently Nevada 3300 XL system specifications, and premature failure under normal operating conditions. Each unit is functionally tested prior to dispatch — including output linearity verification, frequency response check, and insulation resistance measurement — to ensure it meets system-ready standards.
