Quick Detail

Description

The 330930-040-00-00 3300 NSv Extension Cable is a high-performance accessory designed for Bently Nevada’s 3300 NSv Proximity Transducer system, providing reliable signal transmission in demanding industrial automation environments. With a cable length of 4.0 meters (13.1 feet) and unarmored construction for flexible installation, this extension cable supports precise monitoring of radial and axial shaft vibration in centrifugal air compressors, refrigeration compressors, and other critical machinery. Engineered to operate across a wide temperature range from -52°C to +177°C (-62°F to +351°F), the cable ensures stable electrical performance in harsh process conditions. Compatible with probes using 0.2 to 1.5 mm² field wiring (16–24 AWG), it maintains a linear range of 1.5 mm (60 mils) and a recommended gap setting of 1.0 mm (40 mils). The cable’s low output resistance of 50 Ω and supply sensitivity of less than 2 mV voltage change per volt input ensures high-fidelity signal transmission, enabling reliable condition monitoring and predictive maintenance for automation systems. Its mechanical and electrical compatibility with previous 3300 RAM components simplifies upgrades and replacement in existing 3300 NSv installations. Constructed with PPS probe tip material and AISI 304 stainless steel case, it combines chemical resistance and durability for long-term use in process-critical automation applications.

Applications

1. Radial Vibration Measurement
Used in centrifugal compressors and small-shaft equipment, the extension cable ensures accurate transmission of radial vibration signals from 3300 NSv probes with a linear range of 1.5 mm, enabling automated monitoring of shaft health and early detection of misalignment or imbalance.

2. Axial (Thrust) Position Monitoring
Supports axial position measurements in process machinery, allowing precise control of thrust bearings. The cable’s high-temperature tolerance of up to 177°C ensures reliable operation in automated systems for axial vibration detection.

3. Tachometer Signal Transmission
Enables accurate speed monitoring in automation setups, transmitting tachometer or zero-speed signals with minimal voltage deviation (<2 mV per V), critical for real-time machine control and predictive maintenance strategies.

4. Phase Reference (Keyphasor) Signal Distribution
Provides consistent phase reference signals from 3300 NSv probes to monitoring systems, supporting synchronization of vibration data for advanced automation and control systems, especially in high-speed compressor applications.

5. Retrofit and Upgrade Automation
Allows automation engineers to upgrade from older 3300 RAM or 3000/7000-series systems without full replacement, leveraging existing NSv probes and monitoring modules to improve automation reliability while minimizing downtime and installation costs.
