Introduction
The Bently Nevada 330190-040-00-00 is a 3300 XL ETR Extension Cable developed for proximity transducer installations that require extended-temperature capability. It provides the electrical connection between a compatible 3300 XL ETR proximity probe and its Proximitor Sensor, helping maintain the complete transducer system's specified electrical characteristics.
This particular configuration provides a 4.0 m (13.1 ft) nominal cable length, standard non-armored construction, and the standard approval configuration. Its PFA-insulated cable construction makes it well suited to demanding machinery environments where temperature exposure is a major consideration.
For maintenance and replacement work, the 330190-040-00-00 is especially useful when the existing installation requires a four-meter extension cable. Matching the exact cable family and total probe-plus-extension length is important because the 3300 XL proximity system is designed around defined electrical characteristics rather than cable length alone.

Applications
Steam Turbine Monitoring
The 330190-040-00-00 is suitable for appropriately engineered steam-turbine monitoring systems where proximity probes are installed in elevated-temperature areas and require an ETR-rated extension cable.
Gas Turbine Equipment
Gas turbines and associated rotating equipment can expose instrumentation cabling to substantial heat. The 3300 XL ETR cable family provides a purpose-designed option for these demanding environments.
Compressor Protection
Critical compressors frequently use proximity transducers for direct shaft vibration and position measurement. A 4.0 m extension can provide useful routing distance between the probe and Proximitor Sensor.
Generator Systems
The cable can be incorporated into generator shaft-monitoring installations where the sensing location and signal-conditioning electronics are physically separated.
Fluid-Film Bearing Machines
3300 XL proximity systems are well suited to machines using fluid-film bearings because the probe directly measures shaft movement. The extension cable provides the required connection to the Proximitor Sensor.
High-Temperature Proximity Measurement
The principal reason for selecting the 330190 family is its Extended Temperature Range construction. PFA insulation provides the thermal capability required by installations where ordinary extension cable may not provide the desired performance.
Machinery With Longer Cable Runs
The 4.0 m length offers additional routing flexibility compared with 3.0 m and 3.5 m configurations. It can be useful when the Proximitor Sensor is mounted farther from the probe while still avoiding an unnecessarily long cable.
Advantages
Extended-Temperature Construction
The 330190 family is specifically intended for ETR applications, giving the 330190-040-00-00 an important advantage in hot machinery environments.
Convenient 4-Meter Length
A 4.0 m cable provides a practical balance between installation reach and cable management. It can accommodate installations where shorter extension cables do not provide sufficient routing distance.
Slim Cable Profile
With an approximately 3.7 mm maximum cable diameter, the non-armored version can be routed through comparatively restricted spaces without the additional bulk of armored cable.
PFA Insulation
PFA provides the thermal characteristics required by the 3300 XL ETR cable design and is one of the defining differences between ETR and standard extension-cable configurations.
75 Ω Triaxial Construction
The controlled 75 Ω triaxial design is intended to maintain the electrical performance required by the 3300 XL proximity transducer system.
Reliable ClickLoc Connection
The miniature coaxial ClickLoc connector provides a practical connection arrangement for the compatible 3300 XL probe and Proximitor Sensor architecture.
Non-Armored Flexibility
The 00 configuration is useful when additional mechanical armor is unnecessary. Its smaller cable profile can simplify installation and reduce routing congestion.
Useful Replacement Configuration
For machinery already equipped with a 4.0 m 3300 XL ETR extension cable, this model provides a straightforward configuration match, helping maintenance teams avoid unnecessary changes to the existing installation.
System-Level Compatibility
The cable is intended to operate as part of a complete 3300 XL ETR transducer system. When the probe, extension cable, and Proximitor Sensor are correctly matched, the resulting arrangement supports dependable shaft vibration and position monitoring.
Technical FAQs
