Quick Detail

Description

The 330730-080-00-CN 3300 XL 11 mm Extension Cable is an 8.0-meter (26.2 ft) standard cable designed for 3300 XL 11 mm probes, providing 50 Ω output resistance and less than 2 mV/V supply sensitivity. Constructed with 75 Ω triaxial FEP insulation and optional AISI 302 SST armor, this extension cable maintains high-fidelity transmission for non-contacting vibration and displacement measurements. The 330730-080-00-CN 3300 XL 11 mm Extension Cable supports automated monitoring of axial thrust, rod drop, ramp differential expansion, and Keyphasor phase signals with 3.94 V/mm output from the 3300 XL 11 mm probes. ClickLoc connectors and CableLoc design provide 330 N pull strength, while optional FluidLoc and connector protectors prevent oil and moisture ingress. Compatible with 7200-series 11 mm and 14 mm upgrades, the 330730-080-00-CN 3300 XL 11 mm Extension Cable ensures reliable signal linearity over long runs and supports high-density DIN-rail or panel mount configurations. SpringLoc terminal strips allow rapid, tool-free field wiring, enabling efficient installation in automated plant environments.

Applications

Measure thrust position on steam turbine shaft

By using 330730-080-00-CN 3300 XL 11 mm Extension Cable, the 11 mm probe signal is transmitted through the 75 Ω triaxial line to the monitoring rack. The 50 Ω output resistance of 330730-080-00-CN 3300 XL 11 mm Extension Cable allows accurate axial movement measurement over the full 8.0 m run, enabling operators to trip the turbine when thrust displacement exceeds limits.

Track differential expansion during turbine startup

During warm-up, casing and rotor expand at different rates. The −52°C to +177°C rating of 330730-080-00-CN 3300 XL 11 mm Extension Cable allows installation near hot turbine casings. The low supply sensitivity (<2 mV/V) of 330730-080-00-CN 3300 XL 11 mm Extension Cable keeps expansion readings correct even when control cabinet voltage changes during motor starting.

Detect rod drop in reciprocating compressors

Mounted on compressor frames, the probe sends piston rod position through 330730-080-00-CN 3300 XL 11 mm Extension Cable to the protection relay. Because 330730-080-00-CN 3300 XL 11 mm Extension Cable supports 0.2–1.5 mm² field wiring, it connects directly to plant terminals and delivers the displacement signal required for shutdown logic.

Provide keyphasor reference for rotating equipment

A phase reference probe connected through 330730-080-00-CN 3300 XL 11 mm Extension Cable outputs one pulse per revolution. The triaxial shielding of 330730-080-00-CN 3300 XL 11 mm Extension Cable reduces motor electromagnetic pickup so the monitoring system can calculate shaft phase and orbit.

Specifications

Competitive Advantage

Carry probe signal across long plant routing distance

The 8.0 m length of 330730-080-00-CN 3300 XL 11 mm Extension Cable allows routing from machine casing to control cabinet. With 50 Ω output resistance, 330730-080-00-CN 3300 XL 11 mm Extension Cable maintains signal amplitude over long cable trays inside turbine halls.

Install close to high temperature bearing housing

Because 330730-080-00-CN 3300 XL 11 mm Extension Cable operates up to 177°C and uses FEP insulation, the cable can be mounted beside journal bearings without extra protection conduit.

Connect directly into monitoring rack terminals

The conductor range supported by 330730-080-00-CN 3300 XL 11 mm Extension Cable matches standard automation terminal blocks. Technicians can wire 330730-080-00-CN 3300 XL 11 mm Extension Cable directly into the protection system without intermediate adapters.

Avoid false shutdown during power fluctuation

The supply sensitivity below 2 mV per volt means 330730-080-00-CN 3300 XL 11 mm Extension Cable keeps the vibration signal level unchanged when panel power varies, allowing the monitoring system to trigger trips only when real shaft movement occurs.
