Technical FAQs
1. What is the primary function of this proximity probe?
It measures shaft vibration, shaft position, and shaft displacement using non-contact eddy-current sensing technology.
2. What does the "30" option indicate?
The 30 option specifies a 3.0-inch (76.2 mm) unthreaded probe length.
3. What is the overall case length?
This model has a 6.3-inch (160.0 mm) overall case length, making it suitable for installations requiring additional probe reach.
4. What cable length is included?
The probe is supplied with a 1.0-meter (3.3-foot) integrated standard cable.
5. Which connector is used?
It utilizes a Miniature ClickLoc™ coaxial connector that provides secure electrical connections and simplified installation.
6. What does the "Option 00" approval indicate?
Option 00 indicates the standard configuration without CSA, ATEX, or IECEx hazardous-area approvals. It is intended for general industrial installations.
7. Which equipment commonly uses this probe?
It is commonly installed on turbines, compressors, generators, pumps, motors, and other fluid-film bearing machines requiring continuous shaft monitoring.
8. Can this probe operate independently?
No. It must be paired with a compatible 3300 XL Proximitor Sensor and the appropriate extension cable to form a complete transducer system.
9. Why choose a longer probe body?
A longer probe body provides greater installation flexibility for equipment with thick bearing housings or recessed mounting locations.
10. Is this probe designed for continuous online monitoring?
Yes. It is engineered for permanent installation in machinery protection and condition monitoring systems operating continuously.
