2. Product Series

The 330881-28-04-150-00-02 belongs to the 3300 XL 8 mm Proximity Transducer System, specifically within the 330881 Proximity Probe Assembly Series.

This system is widely used for continuous monitoring of rotating machinery conditions such as:

• Shaft vibration monitoring
• Radial displacement measurement
• Axial position detection
• Rotor eccentricity monitoring
• Thrust position monitoring

A complete monitoring system includes:

• 330881 proximity probe (sensor element)
• 330880 extension cable (signal transmission)
• Proximitor sensor module (signal conversion and output)

The probe is the core sensing element responsible for converting mechanical shaft motion into electrical signals.

3. Product Introduction

The 330881-28-04-150-00-02 is an 8 mm eddy current proximity probe designed for precise, non-contact measurement of rotating shaft movement.

It operates by generating a high-frequency electromagnetic field at the probe tip. When a conductive target such as a rotating shaft enters this field, eddy currents are induced, and the resulting changes are converted into a proportional electrical signal.

This specific configuration includes a 1.50 m integrated cable length, providing extended routing capability for installations where sensor placement is farther from the connection interface.

The “04” mounting configuration indicates a specialized installation structure designed for mechanical alignment flexibility.

The probe is engineered for continuous industrial operation, offering stable signal output, high repeatability, and strong resistance to harsh environmental conditions.

5. Product Function Description

The 330881-28-04-150-00-02 serves as a key sensing component in rotating machinery monitoring systems.

It continuously measures the distance between the probe tip and the rotating shaft surface. Any variation caused by vibration, imbalance, misalignment, or mechanical wear is converted into an electrical signal.

The monitoring system interprets these signals to evaluate machine conditions such as rotor instability, bearing degradation, and shaft misalignment.

The probe is calibrated within a complete system to ensure consistent accuracy and long-term measurement stability.
