Product Introduction
Compact Metric Design with Proven 3300 XL Monitoring Technology
The 330103-00-03-05-02-RU converts the distance between the probe tip and the conductive shaft surface into a proportional electrical signal. This allows the connected monitoring system to detect both dynamic vibration movement and static shaft position changes, making it suitable for machinery protection and predictive maintenance applications.
The probe is normally integrated with:
-
3300 XL Extension Cable
-
3300 XL Proximitor® Sensor
-
Machinery monitoring system
Together, these components create a complete vibration and position measurement chain for rotating equipment.
Typical measurement applications include:
-
Shaft radial vibration monitoring
-
Rotor displacement measurement
-
Axial position monitoring
-
Keyphasor® reference measurement
-
Speed measurement
-
Turbine and compressor protection
