Reliable Shaft Measurement Technology for Critical Assets
The 3300 XL 8mm Proximity Probe uses proven eddy current sensing technology to provide precise, non-contact measurement between the probe tip and rotating shaft surface. Unlike contact sensors, it does not introduce mechanical wear and can continuously monitor machine behavior during operation.
The 330101 series is designed without armor and uses a 3/8-24 UNF mounting thread, making it ideal for standard installations where mechanical protection from armored conduit is not required.
Key functions include:
-
Radial shaft vibration measurement
-
Shaft displacement monitoring
-
Rotor position detection
-
Bearing vibration analysis
-
Keyphasor® reference applications
-
Turbine supervisory instrumentation (TSI)
The probe works together with compatible 3300 XL extension cables and Proximitor Sensors to create a complete machinery protection measurement chain.
