The Bentley 330105-02-12-10-02-05 is one of the 3300 XL Series 8mm eddy current sensors, and here are the parameters for it:
Probe Specifications: 8mm diameter probe for rotating machinery measuring shaft diameters greater than 24mm.
Mounting: 02 indicates that the probe is mounted in rear.
Non-threaded length: 12 means 12.7mm.
Overall Case Length: 12 means 228.6mm.
Total length: 10 for 1.0 meters, including the total length of the probe cable and extension cable.
Connector & Cable Type: 02 denotes Micro Coaxial Click Loc Connector, Standard Cable.
Agency Certifications: 05 indicates multiple certifications.
Probe Material: The probe tip material is polyphenylene sulfide (PPS) and the probe housing material is AISI 303 or 304 stainless steel.
Weight: about 0.323kg, shipping weight 1.5kg.
In addition, the output voltage of the sensor system is proportional to the distance between the probe tip and the conductive surface being measured, allowing both static (positional) and dynamic (vibration) values to be measured. It is mainly used for vibration and position measurement of fluid membrane bearing machines, as well as keyphase reference and velocity measurement. And, the standard 3300 XL 8mm 5 meter system fully meets API 670 requirements for mechanical configuration, linear range, accuracy, and temperature stability
