—— Product Information ——

The Bently Nevada 330877-080-37-05 is a 3300 XL 50 mm extension cable designed as part of the 3300 XL 50 mm transducer system, manufactured in the USA. It features an 8.0-meter (26.2 feet) FluidLoc extended cable with armor (option 37) and multiple agency approvals (option 05), using a 75 Ω triaxial PFA-insulated construction. The extension cable has a typical capacitance of 69.9 pF/m (21.3 pF/ft), with field wiring support of 0.2 to 1.5 mm² (16 to 24 AWG) recommended using a three-conductor shielded triad cable. Electrical resistance is specified as 1.0 ± 0.25 Ω from center to coaxial conductor and 0.3 ± 0.1 Ω from coaxial to coaxial conductor.
The system is designed for high-reliability operation in harsh turbine environments, with an operating and storage temperature range of -51°C to +200°C (-31°F to +392°F). The 3300 XL 50 mm transducer system consists of a separate 50 mm probe, an extension cable, and a 3300 XL 50 mm Proximitor Sensor, providing a maximum linear range of 27.9 mm (1100 mils). It is ideal for measuring differential expansion (DE) or rotor expansion (RX) in large steam turbine generators, and features FluidLoc cable, stainless steel armor with PFA outer jacket, and high-temperature ClickLoc connectors for durability and contamination resistance.
