2. Product Series

The 330881-16-11-165-07-02 belongs to the 3300 XL 8 mm Proximity Transducer System, specifically within the 330881 Proximity Probe Assembly Series.

This system is part of a complete rotating machinery monitoring architecture used for:

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

A full monitoring system typically includes:

• 330881 proximity probe (sensor element)
• 330880 extension cable (signal transmission line)
• Proximitor monitoring module (signal processing unit)

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

3. Product Introduction

The 330881-16-11-165-07-02 is an 8 mm proximity probe designed for high-precision vibration and displacement monitoring in rotating machinery.

It operates based on eddy current sensing technology. The probe generates a high-frequency electromagnetic field, and any change in the distance between the probe tip and the conductive target surface (typically a rotating shaft) results in a corresponding electrical signal variation.

This model is intended for continuous monitoring applications where long-term stability and measurement accuracy are required.

The probe is manufactured with stainless steel housing and industrial-grade insulation materials, ensuring stable operation under harsh industrial conditions such as high vibration, oil contamination, humidity, and temperature fluctuations.

5. Product Function Description

This proximity probe is a key sensing element in rotating machinery monitoring systems.

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

The monitoring system then analyzes this signal to determine machine health conditions such as shaft instability, bearing wear, rotor imbalance, or alignment issues.

The probe is calibrated as part of a complete measurement system to ensure consistent accuracy and repeatability under real operating conditions.

6. Application Areas

The 330881-16-11-165-07-02 is widely used in industrial condition monitoring and machinery protection systems.

Typical applications include:

• Steam turbine vibration monitoring
• Gas turbine shaft displacement measurement
• Centrifugal compressor condition monitoring
• Axial compressor protection systems
• Industrial pump vibration monitoring
• Large motor condition monitoring
