Q1: What is the primary function of the 330103-00-03-50-02-00?
It is an eddy-current proximity probe used for non-contact measurement of shaft vibration, axial position, and rotational speed on rotating machinery. It outputs a voltage proportional to the gap between the probe tip and the conductive shaft surface, enabling real-time condition monitoring and protection.
Q2: What do the part number segments mean for this probe?
330103 = 8 mm probe, M10×1 metric thread, non-armored
-00 = 0.0 mm unthreaded length (fully threaded)
-03 = 30 mm overall case length
-50 = 5.0 meter cable length
-02 = Miniature coaxial ClickLoc™ connector, standard cable
-00 = No agency approvals (general-purpose)
Q3: Which Proximitor sensor is required for this probe?
The total electrical length of the probe plus extension cable must equal the rated system length of the Proximitor. Since this probe has a 5.0 m cable, you must pair it with a 5.0 m Proximitor sensor (e.g., 330180-50-00). Mismatched components can cause measurement errors of 20% or greater.
Q4: What is the recommended installation gap and corresponding voltage?
The optimal gap is 1.27 mm (50 mils), which yields an output voltage of approximately -9.0 VDC at the Proximitor. The linear operating range spans approximately -1 VDC to -17 VDC.
Q5: Is this probe interchangeable with other 3300 XL components?
Yes. All 3300 XL 8 mm system components are designed for full interchangeability. Probes, extension cables, and Proximitor sensors can be mixed and matched without bench calibration, provided the total electrical lengths match. They are also backward-compatible with previous 3300 series 5 mm and 8 mm systems.
