Technical FAQs
1. What does this proximity probe measure?
It measures shaft vibration, shaft position, and shaft displacement using proven non-contact eddy-current 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 features a 6.0-inch (152.4 mm) overall case length, making it suitable for deeper installation requirements.
4. What cable length is supplied?
The probe includes a 0.5-meter (1.6-foot) factory-installed standard cable.
5. Which connector is used?
It uses a Miniature ClickLoc™ coaxial connector, allowing quick installation while maintaining reliable electrical performance.
6. Does this model include hazardous-area certifications?
Yes. The Option 05 configuration includes CSA, ATEX, and IECEx approvals for qualified hazardous-area applications.
7. Which machines commonly use this probe?
It is commonly installed on turbines, compressors, generators, pumps, motors, and other fluid-film bearing machines requiring continuous shaft monitoring.
