Product Details

330101-00-11-10-02-00 Product Description

The Bently Nevada 330101-00-11-10-02-00 is a high-precision eddy-current proximity probe engineered for seamless integration within the 3300 XL Series machinery protection and monitoring architecture. Designed to deliver continuous, non-contact displacement and vibration measurements on rotating shafts, this probe serves as the primary sensing element at the field layer of a complete condition monitoring system. Its role extends far beyond simple signal acquisition — it anchors the entire measurement chain that feeds critical data upward through the proximitor driver, signal conditioning modules, monitor rack, and ultimately into the plant-level SCADA or DCS platform.

In a fully deployed 3300 XL architecture, the 330101-00-11-10-02-00 probe operates in conjunction with the 330180 Proximitor® driver, which conditions the raw eddy-current signal into a calibrated DC voltage proportional to the gap between the probe tip and the target shaft. This conditioned output is then routed to a 3300/16 or 3300/20 monitor rack, where dedicated I/O modules — such as the 3300/25 Keyphasor® module or the 3300/46 Tachometer module — process the signal alongside phase reference data to enable full vector analysis of shaft motion. The result is a layered, redundant measurement platform capable of detecting imbalance, misalignment, rub, oil whirl, and other rotor dynamic faults with sub-micron resolution.

System architects deploying this probe in power generation, petrochemical, or oil and gas facilities will recognize its compatibility with the broader Bently Nevada System 1® software environment. Data acquired through the 330101-00-11-10-02-00 feeds directly into System 1 condition monitoring nodes, enabling trend analysis, alarm management, and predictive maintenance workflows without requiring additional signal conversion hardware. This Contextual Integration capability ensures that the probe's output is immediately actionable within the plant's existing digital infrastructure, reducing commissioning time and eliminating interoperability risk.

From an electrical standpoint, the probe operates on a standard -24 VDC supply delivered through the proximitor driver, with a nominal sensitivity of 7.87 V/mm (200 mV/mil) and a linear measurement range of 0.25 mm to 2.29 mm (10 to 90 mil). The armored cable assembly provides robust EMI shielding, making the probe suitable for installation in high-noise environments adjacent to variable frequency drives, power transformers, and motor control centers. The stainless steel housing and IP67-rated connector ensure long-term reliability in humid, chemically aggressive, or high-vibration plant environments.

For control cabinet and panel builders integrating this probe into a new or retrofit monitoring system, the 330101-00-11-10-02-00 is fully compatible with standard DIN-rail mounted junction boxes and terminal blocks used in conjunction with 3300 XL extension cables. When paired with the 330130 or 330140 extension cable series, the probe-to-proximitor distance can be extended to meet the physical layout requirements of large turbine pedestals, compressor trains, or pump skids without signal degradation. This modular cabling architecture supports rapid field replacement and minimizes downtime during scheduled maintenance windows.

In redundant protection architectures — common in critical rotating equipment such as steam turbines, gas compressors, and boiler feed pumps — dual-probe configurations using two 330101-00-11-10-02-00 units mounted at 90° XY orientation provide full radial vibration coverage per API 670 requirements. Each probe feeds an independent channel within the 3300 rack, ensuring that a single sensor failure does not compromise the protection function. This redundancy design is further supported by the rack's built-in channel-to-channel comparison logic, which can trigger alerts when probe outputs diverge beyond a configurable threshold — a key diagnostic capability for long-term asset health management.

Every unit supplied by NANKMOS undergoes pre-shipment functional testing against Bently Nevada factory calibration standards, verifying sensitivity, linearity, and connector integrity before dispatch. All units are covered by a 12-Month Warranty from the date of shipment, with in-stock availability supporting urgent replacement and planned maintenance schedules alike. Our technical team can assist with system configuration, cable length selection, and rack slot assignment to ensure a complete, validated installation from day one.

The 330101-00-11-10-02-00 proximity probe is most effective when deployed as part of a fully integrated Bently Nevada 3300 XL monitoring platform. At the field sensing layer, the probe connects to the 330180 Proximitor® driver, which provides the oscillator-demodulator circuitry required to convert the raw eddy-current impedance change into a usable DC voltage signal. This signal is then routed via 330130 or 330140 extension cables to the monitor rack, where it enters a dedicated input channel on the 3300/16 Dual Voting Logic or 3300/20 Radial Vibration Monitor module.

Within the rack, the 3300/25 Keyphasor® module provides the once-per-revolution phase reference signal essential for synchronous vibration analysis, while the 3300/46 Tachometer module delivers speed tracking data used by the protection logic to apply speed-dependent alarm setpoints. The rack's backplane distributes power from a 3300/05 Power Supply module — available in redundant configurations — ensuring uninterrupted monitoring even during power supply maintenance. Relay output modules within the rack interface directly with the plant's safety instrumented system (SIS) or distributed control system (DCS), enabling automated trip actions when vibration thresholds are exceeded.

At the communication and data layer, the 3300 XL rack connects to Bently Nevada System 1® Evolution software via a dedicated Ethernet gateway, enabling real-time waveform capture, spectrum analysis, and long-term trend storage. For facilities integrating legacy analog infrastructure with modern digital networks, the rack's 4–20 mA retransmission outputs can feed Modbus RTU or Modbus TCP gateways — such as the Bently Nevada 3500/92 Communication Gateway — allowing vibration data to appear as standard process variables within the plant's OPC-UA or SCADA historian. This architecture eliminates the need for separate signal converters and preserves measurement fidelity across the entire data chain from probe tip to control room display.

Power Generation: In steam turbine and gas turbine applications, the 330101-00-11-10-02-00 is installed at the journal bearing locations to monitor radial shaft displacement continuously. Paired with axial position probes and Keyphasor® sensors, it provides the complete vibration dataset required for API 670-compliant turbine protection systems. The probe's high-temperature rating supports installation in hot sections of the turbine pedestal without signal drift.

Petrochemical and Oil & Gas: Centrifugal compressors and process pumps in refinery and upstream production environments rely on this probe for early detection of rotor instability, bearing wear, and seal degradation. Its compatibility with hazardous area installation practices — including intrinsically safe barriers and explosion-proof junction boxes — makes it suitable for Zone 1 and Zone 2 classified areas under IEC 60079 standards.

Water Treatment and Mining: Large vertical pumps, horizontal multistage pumps, and crusher drive motors in water infrastructure and mining operations benefit from continuous shaft monitoring to prevent catastrophic bearing failures. The probe's robust stainless steel construction and IP67 rating ensure reliable operation in wet, dusty, and chemically aggressive environments typical of these industries.

Marine Propulsion and Metallurgy: Shipboard propulsion systems and rolling mill drives in steel production require vibration monitoring solutions that can withstand high ambient vibration, wide temperature swings, and salt-laden atmospheres. The 330101-00-11-10-02-00 meets these demands while maintaining the measurement accuracy required for condition-based maintenance programs that minimize unplanned downtime and extend equipment service intervals.

Q1: Is the 330101-00-11-10-02-00 compatible with both 3300 XL and 3500 Series monitor racks? The 330101-00-11-10-02-00 is natively designed for the 3300 XL Series architecture and is fully compatible with 3300/16, 3300/20, and related 3300 XL rack modules when used with the 330180 Proximitor® driver. Integration with 3500 Series racks is possible using appropriate signal conditioning adapters, but we recommend confirming rack slot assignments and cable specifications with our technical team prior to installation to ensure full system compatibility and alarm setpoint accuracy.

Q2: What is the recommended installation procedure for dual XY probe configurations per API 670? For API 670-compliant radial vibration monitoring, two 330101-00-11-10-02-00 probes should be mounted at 90° to each other (X and Y planes) at each bearing location, with probe tips positioned at the 45° and 135° clock positions relative to the vertical centerline. Each probe requires its own dedicated 330180 Proximitor® driver and independent rack channel. Gap voltage should be set to -10.0 VDC ± 0.5 VDC at the nominal shaft centerline position during commissioning. Cable routing should avoid parallel runs with power cables to minimize EMI-induced noise on the measurement signal.

Q3: What does the 12-Month Warranty cover, and what is the lead time for replacement units? All 330101-00-11-10-02-00 units supplied by NANKMOS are covered by a 12-Month Warranty from the date of shipment, covering manufacturing defects, calibration drift beyond factory tolerance, and connector integrity failures under normal operating conditions.
