Option 51 (5.0 meter system length, DIN mount) and Option 05 (Multiple Approvals) specify this 3300 XL 11 mm Proximitor Sensor configuration — 330780-51-05. The 3300 XL 11 mm system features an incremental scale factor of 3.94 V/mm (100 mV/mil) for non-contact displacement and vibration measurements. The system is used on fluid-film bearing machines where an extended linear range is required, including turbine axial (thrust) position, ramp differential expansion, and reciprocating compressor rod drop monitoring.
This 330780-51-05 sensor processes the RF signal from a compatible 3300 XL 11 mm proximity probe and extension cable, outputting a voltage signal proportional to the distance between the probe tip and the observed shaft surface. The unit mounts on standard 35 mm DIN rails and is compatible with 3500 series machinery protection systems and secondary monitors.
The 330780-51-05 Proximitor Sensor is used in rotating machinery monitoring where an extended linear range is required. Typical application areas include:
