Product Overview
When machine vibration monitoring systems demand uncompromised signal integrity, the Bently Nevada 330930-045-01-00 delivers. This 3300 NSv Extension Cable is a precision-engineered component designed to connect a 3300 XL NSv Proximitor Sensor to its probe, ensuring accurate data transmission in critical rotating machinery applications. Manufactured in the U.S.A., this industrial automation module is built to withstand the harshest operating environments.
The 330930-045-01-00 features a 4.5-meter (14.8 feet) cable length, making it ideal for installations where the sensor must be positioned away from the monitoring equipment. With stainless steel armor and an FEP jacket, this cable offers exceptional mechanical protection and chemical resistance, ensuring long-term reliability.

Applications and Use Cases
The 330930-045-01-00 is designed for use in turbomachinery, pumps, compressors, and other rotating equipment where precise shaft vibration and position monitoring are critical. In a typical installation, the extension cable connects a 3300 XL 8 mm probe to the Proximitor Sensor, which then transmits data to a 3300 XL monitor.
For example, in a steam turbine generator train, this cable enables the Proximitor Sensor to be mounted away from the high-temperature bearing housing, while maintaining signal accuracy. The 4.5-meter length provides flexibility in routing, and the stainless steel armor protects against abrasion and physical damage in harsh industrial environments.
Installation and Setup
When installing the 330930-045-01-00, ensure that the combined length of the extension cable and the probe equals the total length specified for the Proximitor Sensor. This is critical for accurate calibration and proper system operation.
Field wiring between the Proximitor Sensor and the monitor should use a three-conductor shielded triad cable with a maximum length of 305 meters (1,000 feet). Use wire gauges from 0.2 to 1.5 mm² (16 to 24 AWG); if using ferrules, 0.25 to 0.75 mm² (18 to 23 AWG) is recommended. Always route the cable away from high-voltage sources and sharp edges to prevent damage.
Maintenance and Reliability
Regular inspection of the cable and connectors is recommended to ensure optimal performance. Check for signs of wear, corrosion, or physical damage, especially in high-vibration areas. The FEP jacket and stainless steel armor provide excellent resistance to chemicals and abrasion, reducing the need for frequent replacements.
Because the cable is rated for temperatures from -52°C to +177°C, it can be used in extreme environments, from cryogenic processes to high-heat turbine applications. This wide operating range minimizes downtime and extends the service life of the monitoring system.
Buying Guide
Before purchasing, verify that the 330930-045-01-00 is compatible with your existing 3300 XL NSv Proximitor Sensor and probe. Confirm the required cable length and connector options.
