Application & Failure Scenarios
The 3300 XL NSv transducer system is designed for centrifugal air compressors, refrigeration compressors, process-gas compressors and other machinery where probe installation space is restricted. Documented measurement uses include radial vibration, radial position, axial position, tachometer, zero-speed and phase-reference signals.
Enquiries may arise during investigation of abnormal vibration readings, unstable position signals, physical probe damage or a suspected sensor-circuit fault. Incorrect measurements or an unresolved monitoring fault can delay machinery-condition assessment and maintenance decisions. Troubleshooting should consider the complete probe, extension cable, Proximitor sensor and monitor chain.
Technical Specifications
Electrical performance values below apply to the documented transducer system under the manufacturer’s stated test conditions, rather than to the probe in isolation.

Frequently Asked Questions
1. How is the ordering code configured?
The code specifies a 3300 NSv reverse-mount probe with 3/8-24 UNF threads, 0.2 in unthreaded length, 1.2 in overall case length, 0.5 m total probe length, a standard-cable miniature coaxial ClickLoc connector and the Multiple Approvals option.
2. Which machinery applications are documented?
The manufacturer lists compressor applications with restricted installation clearance and measurement uses including radial vibration, radial position, axial position, tachometer, zero speed and phase reference.
3. Is the probe sufficient for a complete monitoring installation?
No. The documented transducer system includes a probe, extension cable and Proximitor sensor connected to monitoring equipment. Confirm the existing system configuration before replacement.
4. Which checks are important before installation?
Verify thread fit, mounting dimensions, probe-to-target gap, cable and connector configuration, and compatibility with the existing transducer system. Follow the manufacturer’s installation torque and clearance guidance.
5. How can the 330906-02-12-05-02-05 pdf/manual/datasheet information be obtained?
Contact AMIKON with the part number to discuss the relevant manufacturer datasheet and documentation requirements. Confirm the ordering configuration and installation conditions against the applicable manufacturer documentation before ordering or commissioning.
