Quick Detail

Description

The 330930-045-05-05 is a high-integrity 3300 NSv Extension Cable specifically engineered by Bently Nevada to provide a reliable signal link within the 3300 NSv proximity transducer system. As a critical 3300 NSv Extension Cable component, this model is designed to bridge the electrical gap between a proximity probe and the Proximitor sensor, ensuring that delicate displacement and vibration data are transmitted without loss. This specific 3300 NSv Extension Cable features a 4.5-meter (14.8 feet) length, offering the necessary reach for complex machinery layouts while maintaining strict electrical specifications. By utilizing this 3300 NSv Extension Cable, operators can ensure that their machinery protection systems receive high-fidelity signals required for monitoring critical assets like centrifugal compressors and high-speed pumps.

The construction of the 330930-045-05-05 is optimized for extreme industrial endurance. This 3300 NSv Extension Cable is equipped with stainless steel armor, providing a rugged physical shield against mechanical crushing, sharp bends, and abrasive surfaces. Unlike standard cables, this 3300 NSv Extension Cable configuration includes a connector protector at the factory level, which seals the connection point against moisture, oil, and dust ingress. Despite its heavy-duty armor, the 3300 NSv Extension Cable maintains excellent electrical performance with a typical capacitance of 69.9 pF/m and a low DC resistance center conductor of 0.220 Ω/m. This ensures that the 3300 NSv Extension Cable preserves the clarity of high-frequency vibration signals even in electrically noisy environments.

Applications

The 330930-045-05-05 3300 NSv Extension Cable is primarily used to facilitate the transmission of non-contact displacement signals in 3300 NSv proximity systems. Its 4.5-meter length is specifically calibrated to work with 5-meter or 10-meter total system configurations, making it essential for monitoring radial vibration and axial shaft position in medium-to-large scale rotating machinery. It ensures that the high-frequency voltage signals generated by the probe tip are delivered to the monitoring electronics with minimal attenuation, supporting the accurate diagnosis of rotor instability or bearing wear.

In environments such as power plants and chemical refineries, this 3300 NSv Extension Cable is used for routing through complex machinery frames where exposure to mechanical hazards is constant. The stainless steel armor allows the cable to be installed in cable trays or conduits alongside other equipment without the risk of being crushed or severed during routine maintenance activities. It is frequently applied in the monitoring of centrifugal compressors and small-bore turbines where the compact nature of the NSv probes requires a robust, flexible, and shielded extension to reach the control cabinet.

The cable serves a critical role in speed sensing and phase reference applications (Keyphasor). By maintaining stable electrical characteristics such as a 69.9 pF/m capacitance, the 330930-045-05-05 ensures that timing pulses for rotational speed remain sharp and distinct. This is vital for the reliable operation of overspeed protection systems and phase-dependent vibration analysis. The wide operating temperature range (-50°C to +175°C) allows the cable to be routed through areas with extreme thermal gradients, such as the hot-end of gas turbines or cold-side pump houses, without losing signal stability.

Specifications

Competitive Advantage

1. Superior Mechanical Resilience with Stainless Steel Armor

The 330930-045-05-05 is distinguished by its high-grade stainless steel armor, which provides an extra layer of protection against the most common causes of sensor failure: cable cutting and crushing. This armored design eliminates the need for expensive secondary conduit in many installations, saving both time and material costs while ensuring the signal path remains intact even in areas with heavy foot traffic or mechanical vibration.

2. Enhanced Signal Stability and EMI Resistance

With a precisely controlled typical capacitance of 69.9 pF/m and a low center-conductor resistance of 0.220 Ω/m, this extension cable excels at preserving signal integrity over its 4.5-meter span. The shielded triaxial-style construction effectively blocks electromagnetic interference from nearby motors and variable frequency drives (VFDs). This ensures that the 3300 NSv Proximitor sensor receives a "clean" signal, reducing the likelihood of false alarms or incorrect data during critical diagnostic window periods.

3. Integrated Connector Protector for Environmental Sealing

The inclusion of a factory-installed connector protector provides a competitive edge by ensuring a moisture-proof and vibration-resistant seal at the junction between the probe and extension cable. This protector prevents process fluids, lubricants, and humidity from entering the gold-plated ClickLoc connector system. By safeguarding the electrical contact points, the 330930-045-05-05 significantly increases the mean time between failures (MTBF) compared to cables without specialized junction protection.
