Product Introduction
This Bently Nevada 330130-070-00-CN extension cable belongs to the renowned 3300 XL series. Specifically, it serves as a critical link between the proximity probe and the Proximitor sensor. The cable length is 7.0 meters (22.9 feet). Moreover, it carries the CN country-specific approval for regional compliance. Manufactured in the U.S.A., this standard cable weighs only 0.238 kg. Therefore, it offers a lightweight yet durable solution for industrial vibration monitoring.
Technical Specifications
The electrical performance of the 330130-070-00-CN is optimized for precision measurement. First, the nominal DC resistance from center conductor to center conductor is 1.54 ± 0.23 Ω at 7.0 meters. Additionally, the resistance from outer conductor to outer conductor is 0.46 ± 0.09 Ω. Furthermore, the typical extension cable capacitance is 69.9 pF/m (21.3 pF/ft). These parameters ensure minimal signal degradation. The system requires a power supply of -17.5 Vdc to -26 Vdc with a maximum consumption of 12 mA. Besides, the output resistance is 50 Ω. For field wiring, the recommended maximum length between the Proximitor sensor and the monitor is 305 meters (1,000 feet).
Mechanical and Environmental Parameters
The physical construction emphasizes robustness and ease of use. The 330130-070-00-CN features patented TipLoc and CableLoc technologies. Specifically, the CableLoc design provides 330 N (75 lbf) pull strength. This ensures a secure attachment between the probe cable and tip. The standard cable includes silicone tape as an alternative to connector protectors. However, avoid using silicone tape in applications exposed to turbine oil. The cable operates effectively within a temperature range of +18°C to +27°C for optimal performance specifications. Meanwhile, it maintains stability under 93% humidity for up to 56 days per IEC standard.
Installation Guide
Proper installation guarantees long-term reliability. First, route the cable away from high-temperature zones exceeding 177°C. Next, maintain a minimum distance of 0.5 meters from heat pipes during parallel runs. When crossing high-voltage cables, place this low-voltage cable underneath and maintain separation. Additionally, use protective conduits for road crossings. The connector should be hand-tightened securely to the probe. Finally, avoid excessive pulling or sharp bending during deployment to prevent internal damage.
