Frequently Asked Questions

1. What does the "RU" suffix indicate?
It designates a Russia/EAC regional approval configuration and does not change the probe's sensing performance.

2. Is this a complete transducer system?
No. It is the probe only. A compatible 3300 5 mm extension cable and Proximitor® Sensor are required for operation.

3. What measurement technology does it use?
It uses eddy-current (proximity) sensing to measure shaft displacement without physical contact.

4. What thread size does the probe use?
The standard 330171 model uses a 1/4-28 UNF threaded case.

5. Which machines commonly use this probe?
It is commonly installed on steam turbines, gas turbines, compressors, pumps, motors, and generators for continuous machinery monitoring.
