Features:
- With a 4.0 meter (13.1 feet) length, this extension cable allows the Proximitor® sensor to be mounted remotely from the probe, accommodating machine layouts where the probe's integral cable is insufficient.
- The "03" connector type includes armor protection for mechanical durability in harsh environments, and the "05" suffix indicates multiple hazardous area approvals.
- Fully compatible with existing non‑XL 3300 series 5mm and 8mm probe systems, allowing seamless integration into legacy installations without requiring a full system upgrade.
The 330930-040-03-05 provides 4.0 meters (13.1 feet) of additional length between a 3300 XL 8mm probe and its Proximitor® sensor. In many turbomachinery installations, the probe must be mounted deep within the machine casing, close to the shaft, while the Proximitor® sensor (which conditions the signal) is best located in a junction box or control cabinet away from heat and vibration. Without an extension cable, the probe's integral cable (typically 0.5m to 1.0m) would be too short for this separation. The 330930-040-03-05 solves this by extending the reach, allowing optimal placement of both components.
The 330930-040-03-05 features a "03" connector type – a standard coaxial connector with integrated armor protection. This armor shields the connector and the cable junction from mechanical damage during installation through conduit, pull boxes, or tight clearances where abrasion and impact could otherwise compromise signal integrity. The connector is designed to mate with standard 3300 XL probes and Proximitor® sensors, but note that the "03" uses a standard (non‑ClickLoc™) coupling mechanism. The "05" suffix indicates multiple hazardous area approvals (e.g., ATEX, CSA, IECEx), making the cable suitable for installation in classified areas such as petrochemical refineries, offshore platforms, and gas processing plants.
Legacy systems are a reality in many industrial plants, and fully replacing a vibration monitoring system can be cost‑prohibitive. The 330930-040-03-05 is fully backward compatible with non‑XL 3300 series 5mm and 8mm probes and extension cables. This means that if an older 3300 series extension cable fails, the 3300 XL version can be used as a direct replacement without changing the probe, Proximitor®, or monitor. The electrical characteristics (capacitance, resistance, signal attenuation) are matched to ensure identical performance.
The 330930-040-03-05 Bently Nevada Extension Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

- Narrow Space Monitoring: Due to its compact probe housing design, it is commonly used in small centrifugal compressors, pumps, and aerospace derivative turbines where the internal installation space is insufficient to accommodate the standard 3300 XL probe.
- Axial and Radial Displacement: Used to measure axial vibration and axial position relative to bearings.
- Special Metal Targets: The NSv series exhibits excellent linear response to non-magnetic metals and is commonly used to monitor stainless steel shafts or generator sets equipped with non-ferromagnetic retaining rings.
- Firmware-free architecture: The probe is internally packaged with a precision sensing coil and contains no electronic microprocessor or storage chip; therefore, there is no firmware and no update issues.
- System-level updates: While the probe itself does not require updates, connected 3500 frame cards (such as 3500/42M) or proximitors may require firmware updates to optimize signal processing algorithms or expand compatibility with newer system software versions.
- Usually, use a multimeter to measure the preamplifier output and adjust the voltage to approximately -10.0 VDC (the exact value depends on the application range).
- In the 3500 frame configuration software, the channel type must be correctly set to "3300 NSv Proximity Probe".
- Material Calibration:If the material of the shaft being measured is not standard 4140 steel, a custom calibration curve or adjustment of the scale factor must be entered in the configuration software to compensate for differences in the metal's electrical/magnetic conductivity.
