It measures shaft position and vibration on rotating machinery (turbines, compressors, pumps, and motors) using non-contact eddy current sensing, giving reliability teams continuous data to detect bearing wear, misalignment, or imbalance before they cause unplanned downtime.

The official 3300 Proximity Transducer System is actually built using 3300 XL-compatible components: probe, extension cable, and Proximitor Sensor. The practical differences come down to the specific probe diameter and length ordered, not a clean generational split between the two model names.

The 8mm probe is the standard configuration and the one that fully complies with API 670 (4th Edition). The 11mm probe extends the linear sensing range to 4 mm (160 mil) with a 3.94 V/mm output and carries hazardous-area approvals, making it the better choice when the 8mm’s reach or area classification isn’t sufficient.

A complete system consists of a proximity probe, a matched extension cable, and a Proximitor Sensor, sold as a set since these three components are calibrated to work together without individual bench calibration.

The probe generates an eddy current field that interacts with the conductive shaft surface. As the gap between probe tip and shaft changes, the Proximitor Sensor outputs a voltage directly proportional to that distance, providing continuous, non-contact position and vibration data.

Yes. The 3300 XL Proximity Transducer System is engineered so probe, extension cable, and Proximitor Sensor can be swapped in the field without individual component matching or bench calibration.

Field verification is performed using a Bently Nevada TK-3 or TK-3E Proximity System Test Kit, which checks the probe’s output against known target gaps to confirm the system is reading correctly.

The standard 3300 XL 8mm, 5-meter configuration fully complies with API 670 (4th Edition) for mechanical configuration, linear sensing range, accuracy, and temperature stability. Confirm the exact configuration needed if API 670 compliance is a project requirement.
