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

This sensor provides precise shaft vibration and position data for turbines and compressors. It integrates smoothly into the Bently Nevada 3300 XL 8 mm monitoring platform. Engineers favor this probe for critical asset protection in power and process industries. Its eddy-current principle allows non-contact measurement with outstanding linearity and repeatability.

Electrical Performance and Output Characteristics

The Bently Nevada 330103-00-05-10-02-CN delivers a sensitivity of 7.87 mV/µm across its entire linear range. Its nominal gap voltage stabilizes at -9.0 Vdc under standard operating conditions. The probe supports a frequency response from DC to 10 kHz without signal attenuation. This broad bandwidth captures both slow shaft drift and sudden transient events. Furthermore, the integrated EMI shielding reduces electrical noise from variable-frequency drives effectively.

Mechanical Design and Installation Features

The probe housing utilizes a 3/8-24 UNF-2A thread for simple and secure mounting. Its total 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 robust coaxial connector. This cable length eases installation through complex machinery layouts. Moreover, the single internal coil generates a stable high-frequency field for dependable gap voltage output.
