Features:
- 4.0-meter extension cable with stainless steel armor and FEP jacket provides mechanical protection against crushing, abrasion, and chemical exposure in process compressor applications.
- Mechanically and electrically compatible with previous 3300 RAM extension cables, enabling partial upgrades where only the Proximitor sensor needs replacement while retaining existing cabling.
- Country-specific approvals for China simplify regulatory compliance for installations in Chinese industrial facilities without additional certification steps.
The 330930-040-03-CN wraps its 4.0-meter length in stainless steel armor, protecting against crushing when cables run through conduit or share space with power wiring. The FEP jacket adds chemical resistance, standing up to oils, solvents, and aggressive media common in process compressor applications. For facilities where standard cables fail within months due to chemical exposure or physical damage, this armored assembly delivers long-term reliability. The integrated connector protector seals the connection against moisture, eliminating field-applied tape.
Upgrading from 3300 RAM systems? The 330930-040-03-CN works with your existing probes and monitoring systems. Replace only the Proximitor sensor with an NSv version, keep your current cabling, and gain the chemical resistance and side-view improvements of the NSv platform. For 3000 or 7000-series upgrades, you must replace everything—probe, cable, and Proximitor—but the 330930-040-03-CN is ready as a drop-in replacement. One cable serves both upgrade scenarios.
The 330930-040-03-CN carries country-specific approvals for China, eliminating the need for separate certification processes when installing in Chinese facilities. For multinational projects, this means faster delivery and lower compliance costs. The cable retains all the performance characteristics of the global NSv series—armor protection, chemical resistance, and compatibility with both RAM and NSv components—while meeting local regulatory requirements. Stock one part number for both international and China-destined equipment.
The 330930-040-03-CN Bently Nevada 3300 NSv Extension Cable may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Small high-speed machinery monitoring: such as small air compressors, high-speed blowers, aircraft engine test benches, and gearboxes.
- Bearing housing space constraints: due to its smaller head diameter and better sidewall clearance resistance, it is suitable for compact locations where standard probes (e.g., 8mm) cannot be installed.
- Radial vibration and displacement: used to measure the relative motion between the shaft and the bearing, preventing bearing wear or rotor contact.
- Electrical Interface: Equipped with a Bently Nevada standard Miniature Coaxial Connector. Dedicated connector protectors are recommended to prevent moisture and chemical corrosion.
- System Link: The probe must be connected to a 3300 NSv extension cable, ultimately connecting to a 3300 NSv Proximitor preamplifier. The entire system converts physical displacement into a dynamic voltage signal (standard sensitivity 200 mV/mil or 7.87 V/mm).
- Backend Integration: The preamplifier output can be connected to a 3500 monitoring system or a 990/991 transmitter (converted to 4-20mA) for communication with a DCS or PLC.
- China Local Certification (-CN): Complies with Chinese national explosion-proof standards (such as GB3836 series) and typically obtains intrinsic safety certification issued by NEPSI (National Instrument and Meter Explosion-proof Safety Supervision and Inspection Station).
- Hazardous Area Classification: Can be used in Zone 0, Zone 1, or Zone 2 explosive gas environments, provided it is used with appropriate Zener Barriers or electrical isolators.
- Material Compliance: The probe head is typically made of corrosion-resistant materials such as polyphenylene sulfide (PPS) or ceramics, meeting the chemical industry's requirements for acid and alkali resistance and oil stain resistance.
