Description
The Bently Nevada 330104-00-10-10-02-CN is a specialized 3300 XL series Proximitor sensor, engineered for machinery protection systems where vibration and position monitoring are non-negotiable. This specific model is configured for a 9.0 meter total system length, allowing it to interface with 8mm probes and extension cables to provide a standardized voltage output proportional to the distance between the probe tip and the observed shaft.
In high-speed turbo-machinery—such as gas turbines, steam turbines, and large centrifugal fans—this sensor acts as the primary “eyes” for the control system, detecting sub-micron movements before they escalate into mechanical failure. We stock these units to support global plant operators who require immediate, high-spec replacements for their monitoring racks.

Part Number Configuration Breakdown
The 330104 series differs from the 330103 by its default system length calibration. Precision is required here; using a 9m Proximitor with a 5m cable will result in severe linearity errors.

Operational Insights & Field Application
How does this 9-meter system configuration perform in a dense industrial environment? On a recent project involving cooling tower fan gearboxes, we found the 135489-04 and 330104-00-10-10-02-CN combination to be highly effective for long-distance runs where the Proximitor needs to be housed in a junction box away from the machine’s vibration.
The “-02” output option is a critical design choice. Unlike the standard 3300 XL which outputs a negative voltage (-200 mV/mil), this unit provides a 4 to 20 mA current loop. This is actually clever for legacy PLC or DCS integrations that do not have dedicated vibration monitor cards, as it allows the vibration levels to be read as a standard analog input.
Well, technically it is a 9.0-meter system, but don’t underestimate the impact of cable routing. If your 9m total length is coiled tightly near a high-voltage motor lead, you will pick up induction noise—honestly, always use grounded conduit for the extension cable to ensure signal purity.
In my experience, the ClickLoc connectors are robust, but moisture is their enemy. If you are installing this in an outdoor skid, use the 330104’s internal terminations carefully and ensure the connector is wrapped in self-vulcanizing tape. If the “OK” LED on your monitor rack is intermittent, the first place I’d look is a corroded coaxial connection at the Proximitor pigtail.
Global Trade, Shipping, and Logistics Optimization
Shipping high-precision Bently Nevada components to international sites involves navigating complex regulatory landscapes, especially with the “-CN” designation.
Customs & Regional Compliance
The -CN suffix indicates compliance with Chinese standards (like NEPSI or CCC). We classify this hardware under HS Code 9031.80.80. When shipping these to the Asia-Pacific region or the Middle East, we provide a complete document pack: Commercial Invoice, Packing List, and an authenticated Certificate of Origin (COO) to streamline the “Import Inspection” phase at the port of entry.
Logistics and Transit
-
Protection: Every unit is shipped in a moisture-barrier, ESD-shielded bag. We over-box with high-density foam to mitigate the “last-mile” vibration during truck delivery to the plant site.
-
Air Freight: We exclusively use DHL Express or FedEx International Priority for these sensors. Because they are lightweight but high-value, the speed of air freight significantly reduces the “inventory-in-transit” risk.
-
Incoterms: Standard terms are FCA (Free Carrier) or CIP (Carriage and Insurance Paid to).
Trade Finance
To secure your procurement, we accept Telegraphic Transfer (T/T). For critical outages, we can provide “Expedited Release” services upon verification of the bank SWIFT transaction. For long-term frame agreements, we also coordinate via Letters of Credit (L/C).
Frequently Asked Questions
Can I use a 5-meter extension cable with this 9-meter Proximitor?
No. The oscillator inside the 330104-00-10-10-02-CN is tuned specifically for the capacitance of a 9-meter total cable length. Mixing lengths will cause the scale factor to be wildly inaccurate, potentially leading to a failure to trip during a high-vibration event.
What is the benefit of the 4 to 20 mA output?
The 4 to 20 mA output is much more resilient to electromagnetic interference (EMI) over long distances compared to a voltage signal. It also simplifies wiring for non-Bently Nevada control systems.
Does this unit require a -24 V DC power supply?
Yes. Even with a 4 to 20 mA output, the unit requires a negative DC power supply (typically -24 V) to operate its internal sensing circuitry. It cannot be powered by a standard 24 V DC positive supply.
