Product Details

330101-00-24-05-02-05 Product Description

The Bently Nevada 330101-00-24-05-02-05 proximity probe is not a standalone sensor — it is a precision front-end element within a fully coordinated machinery protection and condition monitoring architecture. Its role begins at the sensing layer, where it converts mechanical displacement into a calibrated analog voltage signal, and extends through every tier of the control hierarchy up to enterprise-level asset management systems.

At the I/O and signal conditioning layer, the probe operates in a matched set with the 3300 XL 8mm Proximitor Sensor (330180-91-00), which provides the oscillator drive signal and converts the probe's eddy-current response into a clean DC voltage output. This signal is then routed to the Bently Nevada 3500 Series Monitoring Rack — a modular, 19-inch rack platform that accepts dedicated I/O modules such as the 3500/42M Proximitor/Seismic Monitor and the 3500/40M Proximitor Monitor. These modules perform real-time gap, vibration amplitude, and phase measurement, feeding processed data to both local relay outputs and the plant-wide communication bus.

At the communication layer, the 3500 rack integrates with plant DCS and SCADA platforms via the 3500/92 Communication Gateway, supporting Modbus RTU, Modbus TCP/IP, and OPC-DA/UA protocols. This Contextual Integration capability ensures that vibration and position data from the 330101-00-24-05-02-05 probe is available in real time to operators at the System 1 Evolution software platform — Bently Nevada's condition monitoring and diagnostics environment — enabling trend analysis, alarm management, and predictive maintenance workflows without manual data extraction.

At the control and protection layer, relay outputs from the 3500 rack interface directly with the plant's safety instrumented system (SIS) or emergency shutdown (ESD) logic. In turbine and compressor applications, the probe's radial vibration and shaft position signals are cross-referenced with axial displacement data from companion probes such as the 330101-00-30-10-02-05 (30 mm cable variant) or thrust position probes from the 330500 Series, enabling multi-axis machinery protection with configurable voting logic (1oo2, 2oo3).

At the power layer, the 3500 rack is powered by redundant 3500/15 Power Supply modules, ensuring uninterrupted monitoring even during single power supply failures. This redundancy is critical in continuous-process industries where machinery trips carry significant production cost.

At the HMI and diagnostics layer, the probe's real-time signal can be visualized on plant operator stations running System 1 Evolution or third-party SCADA platforms via OPC-UA. Bently Nevada's TDXnet transient data interface further enables high-speed waveform capture during machinery startups and coastdowns, supporting detailed rotor dynamic analysis and engineering commissioning activities.

For installations requiring modular expansion, the 3500 rack architecture supports up to 14 monitor modules per rack, with multiple racks networked together for large rotating machinery trains. The 330101-00-24-05-02-05 probe is fully compatible with this scalable architecture, allowing engineers to expand monitoring coverage — adding keyphasor inputs via the 3500/25 keyphasor module or temperature monitoring via the 3500/60 temperature monitor — without replacing existing probe infrastructure.

Power Generation & Turbomachinery: In gas turbine and steam turbine installations, the 330101-00-24-05-02-05 probe monitors rotor radial vibration and shaft centerline position at journal bearings. Paired with the 3500/42M monitor and 330500 Series thrust probes, it provides the complete bearing protection suite required by API 670 machinery protection standards. Plants operating GE, Siemens, or MHI turbines rely on this probe series for continuous, uninterrupted protection during baseload and peaking operation.

Petrochemical & Refinery Compressor Trains: In centrifugal and reciprocating compressor applications, the probe's 0.25–2.54 mm linear range and –35°C to +177°C operating envelope make it suitable for high-temperature, high-pressure process environments. Integration with the 3500 rack's Modbus gateway enables compressor vibration data to feed directly into the plant's DCS — such as Honeywell Experion, Emerson DeltaV, or ABB 800xA — for unified process and machinery monitoring.

Water & Wastewater Treatment: Large pump stations and blower installations benefit from the probe's IP67 sealing and corrosion-resistant construction. The 3500 rack's relay outputs can be wired directly to motor control centers (MCCs) for automatic pump shutdown on high-vibration alarm, reducing unplanned maintenance and extending impeller and bearing service life.

Mining & Minerals Processing: Ball mills, SAG mills, and large fan drives in mining operations generate significant shaft vibration. The 330101-00-24-05-02-05 probe, installed at drive-end and non-drive-end bearing housings, provides continuous radial vibration monitoring that feeds into predictive maintenance programs, reducing unplanned downtime in high-value production circuits.

Marine & Offshore: Shipboard propulsion turbines and offshore platform gas compression trains require machinery protection systems certified for marine environments. The probe's wide temperature range and robust construction support DNV-GL and ABS-certified monitoring installations, with the 3500 rack providing the redundant power and communication architecture required for offshore safety cases.

Q1: Is the 330101-00-24-05-02-05 directly compatible with the Bently Nevada 3500 Series rack without additional signal conditioning? Yes. The 330101-00-24-05-02-05 probe is designed as a system-matched component within the Bently Nevada 3300 XL ecosystem. When paired with the 330180-91-00 Proximitor Sensor and connected to a 3500/42M or 3500/40M monitor module, no additional signal conditioning is required. The Proximitor provides the oscillator drive and converts the probe's eddy-current response to a standard –24 VDC analog output that the 3500 rack reads directly. Ensure the extension cable length matches the system-calibrated set (probe + extension + Proximitor must be ordered as a matched set for correct sensitivity).

Q2: What redundancy options are available when deploying this probe in a critical machinery protection application? For API 670-compliant installations, dual-probe redundancy is achieved by installing two 330101-00-24-05-02-05 probes at 90° (X–Y orientation) at each bearing location, each connected to independent Proximitor sensors and separate monitor channels within the 3500 rack. The 3500 rack supports 1oo2 and 2oo3 voting logic for relay outputs, ensuring that a single probe or Proximitor failure does not cause a spurious trip. Redundant 3500/15 power supply modules further protect monitoring continuity. For the highest availability, dual 3500 racks with cross-rack communication via the 3500/92 gateway provide full system redundancy.

Q3: What does the 12-Month Warranty cover, and what is the typical lead time for this part? NANKMOS provides a 12-Month Warranty on the 330101-00-24-05-02-05 from the date of shipment, covering manufacturing defects and functional failures under normal operating conditions. Each unit undergoes pre-shipment functional testing — including gap sensitivity verification and output linearity check — before dispatch. Typical lead time from confirmed order to shipment is 3–7 business days for in-stock units. For urgent requirements, expedited shipping options are available globally.
