330103-06-13-05-02-CN Bently Nevada 3300 XL 8 mm Proximity Probe

You will usually find the Bently Nevada 330103-06-13-05-02-CN Probe on machines where vibration is closely watched — steam turbines, compressors, some fluid-film bearing machines, that sort of equipment. Its main job is radial vibration monitoring and shaft position tracking. Because it works by eddy-current displacement measurement, there is no physical contact with the shaft surface. For many sites running predictive maintenance programs, this kind of non-contact proximity sensor is already standard.

Most technicians set the target gap setting at around 1.27 mm (50 mils). If everything looks right, the signal will sit close to -9 Vdc bias voltage. The probe stays within a linear range of about 0.25 mm to 2.3 mm, with roughly 2 mm (80 mils) of usable movement range. Nothing complicated here, but the setup does make a difference.

Usually no. The 330103-06-13-05-02-CN belongs to the 3300 XL Transducer System, so parts are designed with component interchangeability in mind. In a normal setup, people pair it with a 330130 extension cable and a 330180 Proximitor Sensor without extra bench calibration.

A pretty typical combination is the 330130-045 extension cable together with a 330180-50 or 330180-51 Proximitor Sensor. The total loop length matters more than some people expect — get that wrong and readings may drift.

It is commonly used in equipment where vibration levels stay high for long periods. The probe structure is reinforced with the TipLoc molding method, while the CableLoc design helps reduce cable stress during operation. There is also a ClickLoc coaxial connector, so the connection stays secure and does not loosen easily under constant machine vibration.
