Bently Nevada 330103-08-13-10-02-05 Proximity Probe for Rotating Machinery

This sensor captures precise shaft vibration and position data for turbines and compressors. It integrates seamlessly into the Bently Nevada 3300 XL 8 mm monitoring framework. Engineers choose this probe for critical asset protection in power generation and petrochemical plants. Its eddy-current principle enables non-contact measurement with outstanding repeatability.

Electrical Performance and Output Characteristics

The Bently Nevada 330103-08-13-10-02-05 delivers a sensitivity of 7.87 mV/µm across its linear measurement band. Its nominal gap voltage settles at -9.0 Vdc under standard operating conditions. The probe supports a frequency response from DC to 10 kHz. This wide bandwidth captures both slow shaft drift and rapid transient vibrations. Additionally, the integrated EMI shielding minimizes electrical noise from nearby equipment effectively.

Mechanical Design and Installation Features

The probe body employs a 3/8-24 UNF-2A threaded housing for secure mounting. Its overall length reaches 51.8 mm, while the active tip diameter measures 8.2 mm. This model includes a 7.6-meter extension cable with a reliable coaxial connector. This cable length simplifies routing through complex machinery compartments. Furthermore, the single internal coil assembly produces a stable electromagnetic field for consistent gap readings.
