Quick Detail

Description

The 330877-80-37-00 3300 XL 50 mm Extension Cable is a high-reliability signal transmission component engineered for advanced industrial automation and machinery protection systems. Designed specifically for use within the 3300 XL 50 mm transducer system, this extension cable connects the 50 mm proximity probe to the Proximitor Sensor while preserving signal integrity across long distances and harsh operating environments. With an 8.0 metre (26.2 ft) cable length and a typical capacitance of 69.9 pF/m, the 330877-80-37-00 extension cable ensures accurate displacement measurement across the full 27.9 mm (1100 mils) linear range required for large rotating machinery automation.

The 3300 XL 50 mm Extension Cable utilizes a 75 Ω triaxial FluidLoc cable with PFA insulation and integrated armor, providing excellent resistance to moisture ingress, mechanical stress, and thermal degradation. Rated for continuous operation from -51°C to +200°C, this extension cable is well suited for high-temperature automation environments such as steam turbine casings and generator housings. Its 50 Ω system output resistance and compatibility with 0.2 to 1.5 mm² shielded triad wiring allow stable, low-noise signal transmission to monitoring and control systems. As a critical automation accessory, the 330877-80-37-00 extension cable supports seamless upgrades from legacy 7200 systems when used as part of a complete 3300 XL 50 mm transducer replacement, ensuring long-term measurement accuracy and operational reliability.

Applications

Application 1: Differential Expansion Measurement in Steam Turbines

In automated steam turbine monitoring systems, the 330877-80-37-00 3300 XL 50 mm Extension Cable enables accurate differential expansion measurement by maintaining low capacitance over 8.0 metres. This stable signal transmission supports precise tracking of axial growth differences up to 27.9 mm, reducing the risk of turbine casing or rotor damage during startup and load changes.

Application 2: Rotor Expansion Monitoring in Power Generation

For rotor expansion automation, the extension cable ensures consistent signal quality between the proximity probe and Proximitor Sensor. Its 69.9 pF/m capacitance minimizes phase shift and amplitude loss, allowing control systems to accurately calculate rotor growth during thermal transients in large generators.

Application 3: High-Temperature Machinery Protection Systems

Installed near turbine housings, the 3300 XL 50 mm Extension Cable withstands ambient temperatures up to 200°C without insulation breakdown. This makes it ideal for automation systems operating in confined, high-heat zones where conventional cables would degrade and compromise monitoring accuracy.

Application 4: Long-Distance Sensor Routing in Automation Cabinets

With armored construction and triaxial shielding, this extension cable supports long-distance routing from field-mounted probes to centralized automation panels. The robust design reduces electromagnetic interference, ensuring reliable data delivery to machinery protection and process control platforms.

Application 5: Legacy System Upgrade Projects

During automation upgrades from older 7200-series transducer systems, the 330877-80-37-00 extension cable plays a critical role in ensuring full compatibility with 0.394 V/mm output scaling. When used as part of a complete 3300 XL 50 mm system replacement, it minimizes commissioning time and improves overall measurement performance.
