The 3300 XL 5mm miniature proximity probe provides shaft vibration and position measurement in installations where the larger 8mm probe does not fit. Despite the smaller diameter, the 5mm probe maintains the same electrical interface and connection compatibility with the 3500 Series monitors.
The 5mm probe is particularly useful on small motors, pumps, and gearboxes where space is constrained. It is also used as a redundant probe on large machinery where dual-signal validation is required.
