Product Details

330101-00-36-10-02-05 Product Description

The Bently Nevada 330101-00-36-10-02-05 is a precision eddy-current proximity probe engineered for the 3300 XL Series machinery protection and condition monitoring platform. Designed to deliver continuous, non-contact shaft displacement and vibration measurements, this probe integrates seamlessly into multi-layer industrial control architectures — from the field sensing layer through to the SCADA and historian layers. With a 36-inch (914 mm) armoured cable, a 10 mm probe tip diameter, and a 5-metre extension cable interface, the 330101-00-36-10-02-05 is optimised for turbomachinery, compressors, pumps, fans, and rotating equipment in demanding process environments. Every unit supplied by NANKMOS is tested prior to dispatch and covered by a 12-Month Warranty, ensuring long-term system reliability and minimised unplanned downtime.

In modern industrial control architectures, machinery protection is not an isolated function — it is a critical layer that feeds real-time vibration, position, and speed data upward to the control layer, the safety layer, and the asset management layer. The 330101-00-36-10-02-05 probe, when deployed within a properly configured 3300 XL or 3500 rack system, becomes a foundational sensing node that enables the entire protection and monitoring hierarchy to function with accuracy and confidence. Its eddy-current operating principle ensures immunity to oil contamination, temperature variation, and electromagnetic interference — conditions that are endemic to rotating machinery environments in power generation, petrochemical, and heavy manufacturing facilities.

The 330101-00-36-10-02-05 proximity probe does not operate in isolation — it is the primary sensing element within a layered machinery protection and control architecture. Understanding its system context is essential for correct specification, installation, and long-term performance.

At the field sensing layer, the 330101-00-36-10-02-05 probe pairs with a compatible Bently Nevada 330130-080-00-00 extension cable and a 330180-X1-05 or 330190-080-05 proximitor/oscillator driver to form a complete eddy-current transducer system. The proximitor converts the probe's raw impedance signal into a calibrated DC voltage output, which is then routed to the monitor rack. This three-component probe-cable-proximitor assembly is the fundamental building block of the 3300 XL transducer system and must be treated as a matched set to maintain scale factor accuracy and system certification.

At the monitor and I/O layer, the analogue voltage signal from the proximitor is received by a 3500/42M Proximitor/Seismic Monitor or a 3500/40M Proximitor Monitor installed within a 3500 Rack (3500/05 or 3500/15 mainframe). These monitors perform real-time signal conditioning, alarm setpoint comparison, and relay output actuation. The 3500 rack's 3500/20 Rack Interface Module (RIM) provides the communication bridge between the monitor rack and the plant DCS or safety system, supporting both Modbus RTU and Ethernet/IP protocols depending on configuration.

At the control and safety layer, vibration and position data from the 3500 rack is consumed by the plant's distributed control system — such as a Honeywell Experion PKS, Emerson DeltaV, or ABB System 800xA — where it is integrated into turbine control logic, compressor anti-surge control, and equipment protection interlocks. In safety-instrumented systems (SIS), the vibration data may also feed a Triconex Tricon or Hima HIMax safety PLC for SIL 2/3 machinery trip functions. The 330101-00-36-10-02-05 probe's wide frequency response (DC to 10,000 Hz) ensures that both low-speed shaft position (1× and 2× vibration) and high-frequency structural resonance data are captured without signal degradation.

At the communication layer, the 3500 rack's RIM module supports OPC-DA and OPC-UA data export to plant historians such as OSIsoft PI (now AVEVA PI System), enabling long-term vibration trend analysis, predictive maintenance scheduling, and ISO 10816 / API 670 compliance reporting. Integration with Bently Nevada System 1 condition monitoring software further extends the diagnostic capability, allowing engineers to perform orbit plot analysis, Bode plots, waterfall spectra, and shaft centreline trending from a centralised workstation.

At the power layer, the 3500 rack requires a stable –24 VDC supply, typically sourced from a 3500/15 Power Supply Module or an external regulated DC supply with redundant input capability. Proper power supply sizing and redundancy planning — including the use of a 3500/15-02-02-00 dual-input power supply — is critical to maintaining continuous monitoring during plant power disturbances. The 330101-00-36-10-02-05 probe itself draws minimal current from the proximitor supply, but the overall rack power budget must account for all installed monitor cards and I/O modules.

At the maintenance and diagnostics layer, the 3300 XL transducer system supports in-situ calibration verification using a Bently Nevada TK-3 calibration kit, allowing maintenance teams to verify probe gap voltage, scale factor, and linearity without removing the probe from the machine. This capability significantly reduces maintenance downtime and supports predictive maintenance programmes aligned with ISO 55000 asset management standards. NANKMOS supplies the 330101-00-36-10-02-05 as verified, tested stock with full traceability documentation, supporting both planned maintenance replacements and emergency spare parts requirements.

Power Generation (Gas Turbines & Steam Turbines): In combined-cycle and simple-cycle power plants, the 330101-00-36-10-02-05 is deployed on gas turbine compressor shafts, HP/LP turbine rotor journals, and generator bearing housings to monitor radial shaft vibration and axial position. The probe's ATEX Zone 1 certification makes it suitable for installation in turbine enclosures where flammable gas accumulation is possible. Real-time vibration data feeds the turbine control system for load shedding, speed governing, and emergency trip logic.

Petrochemical & Refinery (Centrifugal Compressors): In ethylene crackers, LNG liquefaction trains, and refinery hydrotreater units, centrifugal compressors operate at speeds of 8,000–30,000 RPM with extremely tight vibration tolerances. The 330101-00-36-10-02-05 probe, installed at the compressor's radial bearing locations, provides the continuous shaft displacement data required for anti-surge control and API 670 machinery protection compliance. Its IP67 rating and –35°C to +121°C operating range ensure reliable performance in both cold-climate outdoor installations and hot process environments.

Water & Wastewater Treatment (Large Pumping Stations): Municipal water authorities and industrial effluent treatment facilities deploy proximity probes on large vertical turbine pumps, horizontal split-case pumps, and blower units to detect bearing wear, shaft misalignment, and impeller imbalance before catastrophic failure. The 330101-00-36-10-02-05's non-contact measurement principle eliminates the wear and drift associated with contact-type displacement sensors, providing consistent measurement accuracy over multi-year service intervals.

Mining & Minerals Processing (SAG Mills & Ball Mills): In copper, gold, and iron ore processing facilities, large grinding mills present extreme vibration environments. Proximity probes installed on pinion shaft bearings and trunnion bearings provide early warning of bearing deterioration, gear mesh anomalies, and structural resonance conditions. The 330101-00-36-10-02-05's robust armoured cable construction and wide temperature tolerance make it suitable for the dusty, high-humidity environments typical of mineral processing plants.

Marine & Offshore (Propulsion & Auxiliary Machinery): On LNG carriers, FPSOs, and offshore drilling platforms, machinery protection systems must meet DNV, ABS, or Lloyd's Register class requirements. The 330101-00-36-10-02-05, when installed within a 3500 rack system certified for marine use, provides the continuous shaft monitoring required for main propulsion turbines, cargo pump turbines, and gas compressor trains. Its compatibility with redundant rack configurations supports the high-availability requirements of marine classification societies.

Q1: Is the 330101-00-36-10-02-05 directly compatible with the Bently Nevada 3500 rack system, or does it require a specific monitor card?

The 330101-00-36-10-02-05 is a 3300 XL 8mm proximity probe that produces a standard –2 to –18 VDC analogue output via its matched proximitor (e.g., 330180 or 330190 series). This output is directly compatible with the 3500/42M Proximitor/Seismic Monitor and the 3500/40M Proximitor Monitor installed in any 3500/05 or 3500/15 mainframe. No signal conversion is required. The probe, extension cable, and proximitor must be ordered as a matched set (same scale factor and gap range) to maintain system calibration and API 670 compliance. NANKMOS can supply matched transducer system sets on request.

Q2: Can this probe be installed in a hazardous area (ATEX Zone 1) without additional barriers or isolators?

The 330101-00-36-10-02-05 probe body and cable assembly are ATEX and IECEx certified for Zone 1 hazardous area installation when used with a compatible ATEX-certified proximitor installed in a safe area or within a certified enclosure. In installations where the proximitor must also be located in the hazardous area, a Zener barrier or galvanic isolator (such as a P+F KFD2 series or MTL 7700 series unit) is required between the proximitor output and the 3500 monitor rack input. NANKMOS recommends consulting the Bently Nevada System Installation Manual (document 141078-01) and the applicable ATEX installation drawing before finalising the hazardous area installation design.
