Parameter Analysis
The 330730-040-00-CN is designed for minimal signal loss and high accuracy. Its low capacitance (69.9 pF/m) and precise resistance values ensure consistent performance with 3300 XL systems. The cable supports a linear range of 4.0 mm (160 mils) with an incremental scale factor of 3.94 V/mm (100 mV/mil) ±10%. The recommended gap setting is 2.5 mm (100 mils).
Application Scenarios
This extension cable is ideal for vibration and position monitoring in turbines, compressors, pumps, and other rotating machinery. It is commonly used in oil, gas, power generation, and petrochemical industries where reliable condition monitoring is critical.
Installation Guide
Install the 330730-040-00-CN between the probe and Proximitor. Ensure connectors are clean and properly torqued. Use the provided silicone tape or optional connector protectors for environmental protection. Avoid exposing connections to turbine oil. Route the cable away from high-temperature sources and sharp edges.
Compatibility
Compatible with 3300 XL 11 mm probes and 3300 XL Proximitor sensors. System length options: 5 or 9 meters including extension cable. Field wiring: 0.2 to 1.5 mm² (16 to 24 AWG), maximum 305 meters (1,000 feet) between Proximitor and monitor.
Maintenance Advice
Periodically inspect the cable for damage, especially at connectors. Keep connectors clean and dry. Replace cable if resistance or capacitance readings deviate from specifications. Use connector protectors in humid environments.
Procurement Advice
When ordering, verify the model number 330730-040-00-CN matches your system requirements. Consider optional armored cable for harsh environments. Ensure agency approval option (00) meets your regulatory needs. Contact TenBN for availability and lead times.
