Description
The Bently Nevada 330730-040-03-00 is a 4.0-meter extension cable designed for the 3300 XL 11 mm Transducer System. This cable provides a reliable connection between the 11 mm proximity probe and the Proximitor sensor, ensuring high-accuracy transmission of eddy current signals for vibration and displacement monitoring in critical rotating machinery.
Features
- Designed for 3300 XL 11 mm transducer systems
- 4.0-meter (13.1 feet) total length
- Armored cable construction with connector protector for enhanced durability in harsh industrial environments
- ClickLoc connector design for secure, reliable signal transmission
- Improved RFI/EMI immunity compared to legacy systems
- Complete interchangeability without requiring individual bench calibration
Applications
- Axial (thrust) position measurements
- Ramp differential expansion measurements on steam turbines
- Rod position or rod drop measurements on reciprocating compressors
- Tachometer and zero speed measurements
- Phase reference (Keyphasor) signals

Installation Guidelines
- Ensure the system is powered down before connecting or disconnecting any transducer components.
- Use ClickLoc connectors to ensure a secure fit; tighten to finger-tight, with a maximum torque of 0.565 N-m (5 in-lb).
- Route cables away from high-power lines or high-EMI sources to maintain signal integrity.
- Ensure the cable is properly supported and protected from mechanical stress or excessive vibration at the connection points.
- When upgrading from 7200-series systems, all components (probe, extension cable, and Proximitor) must be replaced with 3300 XL 11 mm compatible parts.
FAQs
What is the primary function of this extension cable?
It acts as the signal transmission link between the 11 mm proximity probe and the Proximitor sensor, allowing the monitoring system to detect critical faults such as shaft cracks, bearing failures, and rotor-to-stator rubs.
Is this cable compatible with non-XL 3300 series components?
The 3300 XL series is generally backward compatible with older 3300 series 11 mm components, but it is not compatible with the 7200-series transducer systems.
What does the 03 option code indicate?
The 03 option code specifies that the cable is armored and includes a connector protector for added physical protection in industrial settings.
