Product Details

330101-00-13-10-02-00 Product Description

The Bently Nevada 330101-00-13-10-02-00 is an 8mm eddy-current proximity probe engineered as a precision sensing element within the Bently Nevada 3300 XL machinery protection architecture. Designed for continuous shaft vibration, axial position, and differential expansion measurement, this probe operates as the primary signal-acquisition node in a layered condition-monitoring hierarchy — feeding calibrated displacement data to Proximitor® sensors, signal conditioning modules, and ultimately to the System 1 asset management platform for real-time diagnostics and predictive maintenance decisions.

In modern rotating machinery protection systems, the proximity probe is not a standalone component — it is the foundational sensing layer upon which the entire control and protection architecture depends. The 330101-00-13-10-02-00 is factory-matched to the 3300 XL Proximitor® sensor series, ensuring that the probe-cable-sensor assembly maintains the calibrated sensitivity of 200 mV/mil (7.87 V/mm) across the full operating range. This system-matched approach eliminates field calibration uncertainty and guarantees signal integrity from the machine shaft to the monitoring rack.

The 330101-00-13-10-02-00 proximity probe achieves its full diagnostic value only when deployed within a coherent, multi-layer automation and protection architecture. In a typical turbomachinery or compressor train installation, this probe interfaces directly with the Bently Nevada 3300 XL Proximitor® Sensor (330180 series), which conditions the raw eddy-current signal into a calibrated DC voltage proportional to shaft gap. The conditioned output is then routed to a 3500/40M Proximitor® Monitor or 3500/42M Proximitor® Monitor housed within the 3500 Series rack — a modular, 19-inch rack-mount platform that consolidates vibration, position, speed, and temperature channels into a unified protection system.

Within the 3500 rack, the 3500/01 Rack Interface Module (RIM) manages communication between individual monitor cards and the plant DCS or safety system via Modbus RTU, Modbus TCP/IP, or Profibus DP — ensuring that vibration trip signals, alarm states, and dynamic waveform data are available to the control layer in real time. For plants operating on a Rockwell Automation ControlLogix or Allen-Bradley PLC platform, the 3500 rack integrates seamlessly through the RIM's EtherNet/IP gateway capability, allowing the protection system to participate in the broader plant automation network without protocol conversion overhead.

Power integrity for the sensing chain is maintained by the 3500/15 Power Supply Module, which provides redundant -24 VDC rails to all Proximitor® sensors and monitor cards. In high-availability installations — such as LNG compressor trains or steam turbine generator sets — a dual power supply configuration with automatic failover ensures that the sensing layer remains energized even during a single power supply fault, preserving continuous machinery protection without interruption.

At the HMI and asset management layer, dynamic data from the 330101-00-13-10-02-00 probe assembly is ingested by Bently Nevada System 1 Software, where time-waveform, spectrum, and orbit plot analysis enables condition-based maintenance decisions. Integration with OSIsoft PI or AspenTech Mtell platforms extends predictive analytics across the enterprise historian, correlating vibration trends with process variables such as bearing temperature (measured via 3500/60 Temperature Monitor), lube oil pressure, and load conditions.

For installations requiring speed and phase reference, the 330101-00-13-10-02-00 probe array is complemented by a 330980 Keyphasor® Transducer, which provides the once-per-revolution trigger signal essential for synchronous averaging, order tracking, and rotor balancing diagnostics. The Keyphasor® signal is processed by the 3500/25 Keyphasor® Module within the same rack, ensuring phase coherence across all vibration channels.

Terminal and wiring integrity within the control cabinet is maintained through Bently Nevada 3500/92 Rack Configuration Module settings and field-side terminal blocks, while cable routing follows IEC 61158 and ISA-5.1 standards for signal segregation between low-level analog sensing circuits and high-voltage power conductors. This disciplined cable management approach preserves signal-to-noise ratios in electrically noisy environments such as motor control centers, variable frequency drive (VFD) enclosures, and high-current switchgear rooms.

The 330101-00-13-10-02-00 proximity probe is deployed across a broad spectrum of rotating machinery protection applications where continuous, non-contact shaft measurement is a regulatory or reliability requirement:

Oil & Gas / LNG Processing: In centrifugal compressor trains and gas turbine-driven generators, this probe monitors radial shaft vibration at each bearing journal, providing the primary trip signal for API 670-compliant machinery protection systems. Axial position monitoring using paired probes detects thrust bearing wear before catastrophic failure, enabling planned maintenance outages rather than unplanned shutdowns.

Power Generation: Steam turbine and gas turbine installations in combined-cycle power plants rely on 3300 XL probe assemblies for continuous shaft eccentricity, differential expansion, and casing expansion monitoring. The probe's wide frequency response (DC to 10 kHz) captures both slow-roll runout at startup and high-frequency subsynchronous instability events during full-load operation.

Petrochemical & Refining: Reactor charge pumps, boiler feed pumps, and cracked gas compressors in refinery environments operate in high-temperature, chemically aggressive atmospheres. The 330101-00-13-10-02-00's rated operating temperature of -35°C to +121°C and its chemically resistant cable jacket make it suitable for direct installation in these demanding process environments.

Water & Wastewater Treatment: Large vertical turbine pumps and centrifugal blowers in municipal water treatment facilities benefit from continuous vibration monitoring to detect impeller imbalance, cavitation, and bearing degradation — extending asset life and reducing unplanned maintenance costs in 24/7 critical infrastructure applications.

Mining & Minerals Processing: SAG mill drives, ball mill pinion bearings, and large slurry pump installations in mining operations present extreme vibration environments. The 3300 XL probe system's robust construction and wide linear range accommodate the high-amplitude, low-frequency vibration signatures characteristic of these heavy-duty rotating assets.

Marine & Offshore: Propulsion shaft monitoring, diesel generator protection, and gas turbine compressor sets on FPSO vessels and offshore platforms require vibration monitoring systems certified to IEC 60092 and DNV GL marine standards. The 330101-00-13-10-02-00, as part of the 3300 XL system, supports these certification pathways through its traceable factory calibration documentation.

Q1: Is the 330101-00-13-10-02-00 directly interchangeable with other 330101 suffix variants, and what system compatibility checks are required before installation?The 330101 series uses a structured part number where each suffix segment defines probe tip diameter, integral cable length, armored vs. non-armored cable, connector type, and temperature rating. The 330101-00-13-10-02-00 specifies an 8mm tip, 1.0m integral cable, standard (non-armored) jacket, MIL-style connector, and standard temperature rating. Before substituting any suffix variant, verify that the replacement probe's sensitivity specification (200 mV/mil) matches the Proximitor® sensor's calibration curve — mismatched probe-sensor pairs will produce systematic measurement errors that cannot be corrected through software scaling alone. Always confirm the full probe-cable-sensor assembly against the Bently Nevada TN-13 technical note for 3300 XL system matching requirements.

Q2: How does the 3300 XL probe assembly integrate with modern DCS platforms, and what signal conditioning is required at the rack interface?The 330101-00-13-10-02-00 outputs a raw eddy-current signal that requires the 3300 XL Proximitor® sensor for demodulation and scaling. The Proximitor® sensor's buffered output (a DC voltage proportional to gap, plus an AC component representing dynamic vibration) connects to the 3500 Series monitor card's input terminals. The 3500/01 RIM then presents processed alarm, trip, and analog output signals to the DCS via 4–20 mA loops, relay contacts, or digital fieldbus (Modbus, Profibus, EtherNet/IP). No additional signal conditioning is required between the Proximitor® sensor output and the 3500 monitor input — the system is designed as a calibrated, end-to-end assembly.

Q3: What are the long-term maintenance, inventory, and warranty provisions for the 330101-00-13-10-02-00 in a critical machinery protection application?All 330101-00-13-10-02-00 units supplied by NANKMOS are covered by a 12-Month Warranty and undergo pre-shipment functional testing to verify sensitivity, linearity, and connector integrity against factory specifications. For critical applications — particularly API 670 installations where probe replacement requires a planned outage — we recommend maintaining a minimum of one spare probe-cable-sensor assembly per monitored machine train. NANKMOS maintains global stock of 3300 XL series components to support rapid dispatch for both planned maintenance and emergency replacement scenarios.
