Quick Detail

Description

The 330854-040-24-CN 3300 XL 25 mm Extension Cable provides a 4.0-metre (13.1 feet) high-temperature FluidLoc connection for the 3300 XL 25 mm Proximity Probe and Proximitor Sensor. Constructed from 75 Ω triaxial PFA-insulated cable, it maintains precise 0.787 V/mm output and 12.7 mm linear range over long distances. The 330854-040-24-CN 3300 XL 25 mm Extension Cable supports field wiring from 0.2 to 1.5 mm² (16–24 AWG) and optional ferrule connections, enabling seamless integration with automation monitoring systems. Flexible AISI 302 SST armor with PFA outer jacket protects the cable from harsh turbine environments, and the extension cable operates from −35 °C to +200 °C, with short-term exposure up to +250 °C. This 330854-040-24-CN 3300 XL 25 mm Extension Cable pairs directly with 3300 XL 25 mm Proximity Probes to monitor differential expansion (DE) in steam turbines, ensuring accurate rotor and stator measurements in midsize to large generators. Its low capacitance (69.9 pF/m typical) preserves signal quality, while ClickLoc connectors simplify installation in confined spaces, allowing automated systems to collect real-time DE data with minimal signal loss.

Applications

Monitor Differential Expansion in Steam Turbines
The 330854-040-24-CN 3300 XL 25 mm Extension Cable connects 3300 XL 25 mm Proximity Probes to Proximitor Sensors, enabling precise measurement of rotor and stator differential expansion (DE) in midsize and large steam turbine generators. Its 12.7 mm linear range and 0.787 V/mm output maintain signal fidelity across distances up to 4.0 metres.

Integrate with Automated Monitoring Systems
Use the 330854-040-24-CN 3300 XL 25 mm Extension Cable to route probe signals into plant automation controllers or data acquisition systems. Field wiring supports 0.2–1.5 mm² (16–24 AWG), facilitating direct connection to existing control panels for real-time DE monitoring.

Operate in High-Temperature Environments
The 330854-040-24-CN 3300 XL 25 mm Extension Cable withstands continuous temperatures from −35 °C to +200 °C, with short-term exposure up to +250 °C. This allows deployment near turbine casings where heat and vibration are significant, without affecting signal integrity.

Extend Probe Placement Flexibility
Its 4.0 metre length provides flexibility to place 3300 XL 25 mm Proximity Probes in optimal positions relative to collars or ramps, while maintaining signal accuracy. The optional AISI 302 SST armor with PFA jacket shields the cable during tight routing and high-vibration conditions.
