Installation Guidelines
-
Handling: Proximity probes are precision instruments. Handle with care to avoid damaging the probe tip or the coaxial cable.
-
Mounting: Ensure the probe is installed in a rigid, vibration-free bracket to prevent false readings. Use the provided lock nuts to secure the probe at the required gap distance.
-
Wiring: Route coaxial cables away from high-voltage power lines and sources of electromagnetic interference (EMI) to maintain signal integrity.
-
System Integration: This probe must be paired with a compatible 3300 XL Proximitor sensor. Ensure all connections are clean and tightened to the manufacturer's specified torque.
-
Power Down: Always disconnect power to the monitoring system before installing or removing probe components to prevent electrical damage.
FAQ
What is the difference between the -CN and -05 models?
The 330103-00-12-10-02-CN and 330103-00-12-10-02-05 are physically and electrically identical. The primary difference is the regional safety certification: the -CN model is NEPSI-certified for use in China, while the -05 model carries global approvals such as CSA, ATEX, and IECEx.
Does this probe include the Proximitor sensor?
No, the 330103 part number refers to the probe and integrated cable only. A compatible 3300 XL Proximitor sensor is required to complete the transducer system.
What is the measurement range of this probe?
The 3300 XL 8 mm system typically provides a linear measurement range of 0 to 80 mils (0 to 2.0 mm), suitable for most standard vibration and position monitoring applications.
