The 330704-000-100-50-11-00 identifies a Bently Nevada 3300 XL 11 mm Proximity Probe with metric M14 x 1.5 threads and integrated cable armor. It is primarily engineered for non-contact machinery protection, measuring vibration and displacement in harsh industrial environments like turbines.

The 3300 XL 11 mm Proximity Transducer System provides a 3.94 V/mm (100 mV/mil) output for non-contacting vibration and displacement measurements on fluid film bearing machines.The large 11 mm tip enables this transducer system to have a longer linear range compared to the standard 3300 XL 8 mm Transducer System.  It is primarily used in applications where a longer linear range is necessary, including:

Axial (thrust) position measurements

Ramp differential expansion measurements on steam turbines

Rod position or rod drop measurements on reciprocating compressors

Tachometer and zero-speed measurements

Phase reference (Keyphasor) signals
