Product Overview – Bently Nevada 330730-040-12-00
Model: 330730-040-12-00 | Series: 3300 XL 11 mm Extension Cable
This 4.0 meter FluidLoc extension cable is engineered for 3300 XL proximity probe systems. It prevents oil leakage through the cable interior, ensuring machine integrity in turbine and compressor monitoring. The connector protector adds robust moisture defense, while the FEP outer jacket and SST armor deliver extreme durability.
Designed for harsh industrial environments, this cable operates from -52°C to +177°C. Its low capacitance (69.9 pF/m) and controlled DC resistance preserve signal fidelity over long runs. Ideal for vibration, thrust position, and speed measurements in critical rotating machinery.
