Technical Product Report

Model: 330881-28-04-180-03-02


1. Brand Overview

The 330881-28-04-180-03-02 belongs to a widely used industrial machinery condition monitoring product family designed for vibration measurement and rotating equipment protection.

This product line is applied in critical industrial environments where continuous operation, equipment safety, and long-term reliability are essential, including:

  • Power generation plants
  • Oil and gas production facilities
  • Petrochemical processing units
  • Offshore platforms
  • Marine propulsion systems
  • Mining and metallurgy industries
  • Steel and cement manufacturing plants
  • Paper production systems
  • Industrial automation systems

The design focuses on stable measurement performance, long service life, strong environmental resistance, and high compatibility with predictive maintenance systems.


2. Product Series

The 330881-28-04-180-03-02 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, including:

  • 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
  • Proximitor sensor module
  • Monitoring/protection system

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


3. Product Introduction

The 330881-28-04-180-03-02 is an 8 mm eddy current proximity probe designed for accurate, non-contact measurement of rotating shaft vibration and displacement.

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 converted into a proportional electrical signal.

This configuration includes a 1.80 m integrated cable length, making it suitable for installations requiring extended routing distance between sensor and connection point.

The “04” mounting configuration indicates a specialized structural design intended for flexible installation conditions where mechanical layout constraints exist.

The probe is designed for continuous industrial operation, offering stable performance, high reliability, and strong resistance to harsh environmental conditions.

5. Product Function Description

The 330881-28-04-180-03-02 serves as a critical sensing element in rotating machinery monitoring systems.

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

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

The probe is calibrated as part of a complete system to ensure stable and repeatable measurement accuracy over long operational periods.
