Product Positioning
The 330104-00-10-50-02-CN is a complete eddy current proximity transducer system comprising a probe, extension cable, and Proximitor® sensor. It is purpose-built for continuous shaft vibration, axial position, and differential expansion monitoring on critical turbomachinery including steam turbines, gas turbines, compressors, and pumps. The “-CN” suffix denotes the China-market configuration with localized compliance documentation.

Proven Application Environments
- Steam & Gas Turbines – Shaft radial vibration and axial thrust position monitoring per API 670
- Centrifugal Compressors – Continuous rotor dynamic surveillance in petrochemical trains
- Boiler Feed Pumps – High-temperature bearing journal monitoring in power plants
- Gearboxes & Expanders – Differential expansion and eccentricity measurement
- Marine Propulsion Systems – Shaft position feedback in harsh offshore environments
- Hydro Turbines – Low-speed shaft runout and position tracking
Engineering Advantages
- Non-contact measurement – Zero mechanical wear; continuous operation without maintenance intervals
- Wide frequency bandwidth – DC to 10 kHz captures sub-synchronous, synchronous, and high-frequency fault signatures
- High EMI immunity – Shielded coaxial cable and differential Proximitor® circuit reject common-mode noise
- API 670 compliant – Drop-in replacement for existing 3300 XL installations; no recalibration required for same-alloy targets
- Integral cable design – Eliminates field-assembled connectors; reduces installation error and signal loss
- Reverse-polarity protection – Prevents damage during field wiring; reduces commissioning risk
System Architecture & Signal Flow
The 330104-00-10-50-02-CN operates as a three-component eddy current system:
- Probe (330104 series) – Generates a high-frequency electromagnetic field (1.0 MHz nominal) directed at the rotating shaft target. Gap changes modulate field impedance.
- Extension Cable (330130 series, 5 m) – Transmits the modulated RF signal from the probe to the Proximitor® with controlled impedance; maintains system calibration over the specified cable length.
- Proximitor® Sensor (3300 XL) – Demodulates the RF signal and outputs a DC-proportional voltage (–2 to –18 VDC). This signal feeds directly into Bently Nevada 3500 series rack monitors or third-party DCS/PLC inputs via 4–20 mA converters.
Signal chain: Shaft gap → Probe impedance change → Extension cable → Proximitor® demodulation → DC voltage output → Monitor/DCS input

Technical FAQ
Q: Is the 330104-00-10-50-02-CN a direct replacement for the 330104-00-10-50-02-00?
A: Yes. The “-CN” suffix indicates China-market documentation and compliance labeling only. Electrical and mechanical specifications are identical; it is a drop-in replacement.
Q: Can this transducer system be used with non-Bently Nevada monitors?
A: Yes. The –2 to –18 VDC output is compatible with any monitor accepting this signal range. A 4–20 mA signal conditioner is required for DCS/PLC integration.
Q: What target materials are supported without recalibration?
A: AISI 4140 steel is the standard calibration target. Other alloys (Inconel, 17-4 PH, etc.) require a material-specific calibration factor — consult Bently Nevada Application Note 141228.
Q: What is the maximum operating temperature for the probe?
A: The probe is rated to +177°C (+350°F). For higher-temperature applications, consult the 330900 high-temperature probe series.
Q: Do you provide ATEX / IECEx certified units?
A: Hazardous-area certified variants are available. Please specify your zone classification and gas group when inquiring.
Q: What is the warranty policy?
A: Konmask.com provides a 12-month warranty against manufacturing defects from the date of shipment, consistent with OEM warranty terms.
