Bently Nevada 330130-085-01-CN 3300 XL Extension Cable Installation & Maintenance Guide
The Bently Nevada 330130-085-01-CN belongs to the 3300 XL series and serves as a standard extension cable for vibration monitoring systems. It creates a secure connection between the 8 mm probe and the Proximitor sensor. This model features an armored outer casing and measures 8.5 meters (27.9 feet) in length. The suffix “01” denotes the armored cable option, while “CN” specifies country-specific agency approvals. This cable provides a protected pathway for the eddy-current displacement signals that are essential for machine protection.
Core Value
This extension cable provides value through its durable armored construction. Specifically, it safeguards the signal pathway from physical damage and environmental contaminants in harsh industrial settings. The Bently Nevada 330130-085-01-CN maintains high signal integrity, thanks to its 75Ω triaxial design with multi-layer shielding. This design effectively combats electromagnetic interference (EMI) and radio-frequency interference (RFI). Therefore, the 8.5-meter length provides practical reach across turbine decks and through cable trays, while the robust build ensures reliable data for predictive maintenance and machinery protection.
Technical Insights
Firstly, the 330130-085-01-CN has a DC resistance of 1.87Ω ±0.28Ω for the core and 0.56Ω ±0.11Ω for the jacket. It also features a capacitance of 69.9 pF/m. Moreover, the cable’s operating temperature range spans from -40°C to 80°C. The armored sheath delivers robust mechanical protection against crushing and abrasion. Furthermore, its connector protectors help seal the connection points from oil ingress. Importantly, the total length of the probe and the extension cable must match the Proximitor’s length requirements. This match is crucial for maintaining accurate calibration and linearity of the monitoring system.
Installation & Maintenance
Begin by inspecting the connector and armored casing for any signs of shipping damage. During installation, ensure that the total cable length (probe + 330130-085-01-CN extension) corresponds precisely to the specified length of the Proximitor sensor. When routing the cable, maintain a minimum bend radius of 6.8 cm to prevent internal damage to the conductors and shielding. In environments where oil exposure is a risk, use the supplied connector protectors instead of silicone tape. Additionally, regularly inspect the cable for cuts, abrasions, or kinks in the armor. Periodically verify that all connections remain clean and securely fastened to preserve signal integrity over time.
Buyer’s Guide FAQ
1. What is the exact length of the Bently Nevada 330130-085-01-CN cable?
The Bently Nevada 330130-085-01-CN has a length of 8.5 meters (27.9 feet). The “085” in the model number designates this specific length option.
2. What does the “01” suffix indicate in the model number?
The “01” suffix signifies that this model includes armored cable protection. This enhances durability in harsh industrial environments.
3. Is the 330130-085-01-CN compatible with all Bently Nevada systems?
No, this model is specifically designed for use with the 3300 XL 8mm proximity probe systems. It is not compatible with the older non-XL series components.
