The Bently Nevada 330851-01-000-020-10-00-00 / 330851-02-000-040-10-00-05 record contains two 3300 XL 25 mm threaded proximity probe configurations. Both are sensing elements in the 25 mm transducer system, where a controlled probe-to-target gap becomes the electrical displacement signal.

For the first string, Bently Nevada 330851-01-000-020-10-00-00 uses case option 01, no unthreaded length, a 2.0 in case length, a 1.0 m total length, no armor and no agency approval option. The second string, Bently Nevada 330851-02-000-040-10-00-05, uses case option 02, a 40 mm case length, a 1.0 m total length, no armor and multiple approvals.

The matched system for Bently Nevada 330851-01-000-020-10-00-00 / 330851-02-000-040-10-00-05 includes the probe, extension cable and Proximitor Sensor. The probe output is therefore evaluated together with the selected cable length and sensor calibration rather than as an isolated voltage source.
