FAQ

Q1. What is a 330908 proximity probe used for?
A: It’s used to monitor shaft vibration and position in rotating machinery without contact. The probe generates a signal proportional to

the distance between its tip and a rotating shaft, feeding this to a Proximitor sensor for machine

 protection and condition monitoring.

Q2. What does the part number mean?
A: The segments encode features such as thread type, housing length, cable length, connector type, and agency

approvals. For example, “330908” means a 3/8-24 UNF threaded NSv probe base; “70” indicates

 7 m cable; “02” is ClickLoc connector; “05” denotes multi-agency certification.

Q3. What technology does it use?
A: It uses eddy-current sensing — a non-contact electromagnetic technique where variations

in the gap between the probe and a conductive surface produce signals

 proportional to displacement/vibration.
