Quick Detail

Description

The 330877-080-36-00 3300 XL 50 mm Extension Cable is designed for high-performance turbine automation with an 8.0-meter (26.2 feet) total length and 75 Ω PFA-insulated FluidLoc cable. Compatible with the 3300 XL 50 mm Proximity Probe, this extension cable supports a linear range of 27.9 mm (1100 mils) and delivers a 50 Ω output resistance for precise signal transmission. Field wiring uses 0.2–1.5 mm² three-conductor shielded triad cable, ensuring automated monitoring of differential expansion (DE) or rotor expansion (RX) in steam turbines. The 330877-080-36-00 3300 XL 50 mm Extension Cable operates across a temperature range of -51°C to +200°C (-60°F to +392°F), making it suitable for continuous high-temperature environments. Typical capacitance is 69.9 pF/m (21.3 pF/ft), maintaining signal integrity over long distances. Integrating the 330877-080-36-00 3300 XL 50 mm Extension Cable with 50 mm probes and 3300 XL Proximitor Sensors allows automated upgrades from legacy 7200 systems without changing monitor configurations. The cable’s FluidLoc armor and optional PFA jacket prevent moisture ingress and facilitate precise routing through tight turbine casings. With robust connectors and verified output performance, the 330877-080-36-00 3300 XL 50 mm Extension Cable ensures consistent automation data from turbine shafts to control systems.
