The Bently Nevada 330904-00-12-10-01-CN is a high-precision proximity probe designed for continuous monitoring of rotating machinery operating conditions. It belongs to the 3300 XL 8 mm Proximity Transducer System Series, which is widely used for shaft vibration monitoring, displacement measurement, and machinery protection applications in industrial environments.
The probe adopts advanced eddy current sensing technology to achieve accurate non-contact measurement between the probe tip and the rotating shaft. The sensor detects the change in distance between the probe and the conductive shaft surface and converts this mechanical movement into a proportional electrical signal.
The 330904-00-12-10-01-CN is designed for applications that require reliable measurement accuracy, stable signal transmission, and long-term operation under demanding industrial conditions. It is commonly applied to critical rotating equipment such as steam turbines, gas turbines, compressors, generators, motors, and industrial pumps.
The probe continuously monitors shaft vibration, radial displacement, and axial position changes. By providing real-time machine condition information, it helps identify abnormal mechanical behavior, reduce unexpected equipment failures, and improve maintenance efficiency.
The compact 8 mm sensing structure provides installation flexibility and allows the probe to be used in locations where mounting space is limited. The robust industrial construction enables reliable operation under continuous vibration, temperature changes, and mechanical stress conditions.

The 330904-00-12-10-01-CN consists of a sensing tip, protective metal probe body, integrated cable assembly, and electrical connection interface.
The operating principle is based on eddy current sensing technology.
When the probe is energized, it produces a high-frequency electromagnetic field around the sensing tip. When the rotating shaft moves, the distance between the shaft surface and the probe changes.
The variation in gap distance changes the electromagnetic field intensity. The probe converts this change into an electrical output signal proportional to the shaft displacement.
The monitoring system receives and processes the signal to evaluate the operating condition of the rotating machine.
The non-contact measurement design provides:
Steam turbines require accurate shaft monitoring to ensure safe and efficient operation.
