Industrial Technical Specification Report
Proximity Probe Model: 330901-00-40-05-02-00
1. Product Overview
The model 330901-00-40-05-02-00 is a non-contact eddy current proximity probe used for continuous measurement of shaft vibration, axial displacement, and rotor position in rotating machinery systems.
It is designed for industrial environments requiring long-term operational stability, high measurement accuracy, and resistance to harsh mechanical and electrical conditions.
The probe is typically integrated into a complete proximity measurement chain consisting of a probe, extension cable, and signal conditioning module.
Its compact structure allows installation in confined spaces such as turbine casings, compressors, and high-speed rotating equipment assemblies.

5. Product Introduction
This probe operates using the eddy current principle. A high-frequency electromagnetic field is generated at the probe tip. When the probe approaches a conductive metal surface, eddy currents are induced on the target surface.
These changes are converted into an analog signal proportional to the distance between probe and shaft.
The system is designed for continuous online monitoring, making it suitable for critical rotating machinery protection rather than periodic inspection.
The “40” configuration typically represents a specific cable length or installation variant within the system architecture.
