330190-045-00-00 | Bently Nevada 4.5m ETR Extension Cable

Product Overview

When your rotating machinery operates in extreme heat, standard cables can fail, causing costly downtime and unreliable vibration readings. The Bently Nevada 330190-045-00-00 3300 XL Extended Temperature Range (ETR) Extension Cable solves this problem by maintaining signal integrity in environments up to +260°C. This 4.5-meter (14.8 feet) cable is part of the trusted 3300 XL series, engineered for demanding industrial applications where standard cables cannot survive.

Industry Applications

The 330190-045-00-00 is ideal for vibration monitoring on turbines, compressors, and pumps in industries such as power generation, oil & gas, and petrochemical processing. Its extended temperature range allows installation near hot surfaces where standard cables would degrade. For example, in gas turbine applications, the cable can be routed close to bearing housings without concern for heat damage, ensuring accurate vibration data for predictive maintenance.

Installation & Setup Guidance

Proper installation is critical for reliable operation. Observe the minimum cable bend radius of 25.4 mm (1.0 in) to prevent internal damage. Use the recommended field wiring: 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable with tinned wiring. Keep the maximum length between the 3300 XL Proximitor Sensor and the monitor at or below 305 meters (1,000 feet) to avoid signal rolloff. Tighten connectors to 0.565 N•m (5 in•lbf) maximum torque to ensure secure connections without damaging the gold-plated contacts.

Maintenance & Reliability

Routine inspection of the cable and connectors is recommended to catch wear early. Check for cuts, abrasions, or kinks that could compromise performance. The gold-plated connectors resist corrosion, but keep them clean and dry. The ETR cable's PFA insulation withstands high temperatures, reducing the risk of premature failure. By following a simple maintenance schedule, you extend the cable's service life and avoid unplanned downtime.

Compatibility & Integration

The 330190-045-00-00 is designed for use with Bently Nevada 3300 XL 8 mm proximity probe systems. It is electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components when the minimum cable bend radius is observed. This flexibility simplifies upgrades and replacements in existing installations. Always verify compatibility with your specific monitor and probe models before ordering.

Selection Guide & Purchasing Advice

Before purchasing, confirm your required cable length and temperature rating. The 045 option indicates 4.5 metres, and the ETR rating covers -52°C to +260°C. If your application does not require extended temperature, a standard cable may suffice. For high-temperature areas, the 330190-045-00-00 is the right choice.
