Complete Technical Specification, Product Overview and Application Guide
1. Product Introduction
The 330103-05-10-10-12-05 is a precision eddy current proximity probe designed for non-contact measurement of shaft vibration, displacement, and position in rotating machinery.
It is part of the 3300 XL 8 mm proximity probe series, a widely used solution in industrial condition monitoring systems. The probe detects the distance between its sensing tip and a conductive surface and converts that into a stable electrical signal used by monitoring systems.
This model is configured with enhanced environmental options and hazardous area capability, making it suitable for installations where reliability, safety, and durability are critical. It is commonly used in combination with extension cables and signal conditioners to form a complete monitoring system.
