Expert FAQ

Why does this probe have 50mm of unthreaded length?

The unthreaded section allows the probe to slide through a mounting bracket or adapter. This lets you set the exact tip position before securing it with the locknut.

What equipment uses M16 threaded probes?

M16 threads are common on large rotating equipment like industrial turbines, big compressors, large pumps, and generator sets where extra mounting strength is needed.

Why is there a minimum shaft diameter requirement?

The 11mm probe tip needs a sufficiently large, flat target area for accurate measurement. On small shafts, the curved surface affects the calibration and signal linearity.

Can this probe be used for thrust measurement?

Yes. The 3300 XL 11mm probes are commonly used for both radial vibration and axial position (thrust) monitoring on appropriate large-diameter shafts.
