Bently Nevada 330103-05-15-10-02-00 Proximity Probe for Rotating Machinery

This sensor delivers accurate shaft vibration and position measurements for turbines and compressors. It integrates seamlessly into the Bently Nevada 3300 XL 8 mm monitoring system. Engineers select this probe for critical asset protection in power generation and oil refining. Its eddy-current technology enables non-contact sensing with exceptional signal stability.

Electrical Performance and Output Characteristics

The Bently Nevada 330103-05-15-10-02-00 provides a sensitivity of 7.87 mV/µm across its linear range. Its nominal gap voltage settles at -9.0 Vdc under normal operating conditions. The probe supports a frequency response extending from DC to 10 kHz. This wide bandwidth captures both slow shaft movement and rapid vibration events. Moreover, the built-in EMI shielding effectively reduces electrical interference from surrounding equipment.

Mechanical Design and Installation Features

The probe housing uses a 3/8-24 UNF-2A thread for straightforward mounting. Its total length reaches 51.8 mm, while the tip diameter measures 8.2 mm. This model includes a 7.6-meter extension cable with a durable coaxial connector. This cable length facilitates routing through tight machinery spaces. Furthermore, the single internal coil generates a stable high-frequency field for consistent gap voltage output.
