MeloAuto-Trusted PLC & DCS Parts Supplier
This sensor delivers precise shaft vibration and position measurements for turbines and compressors. It integrates smoothly into the Bently Nevada 3300 XL 8 mm monitoring platform. Engineers choose this probe for critical asset protection in power generation and hydrocarbon processing. Its eddy-current technology enables non-contact sensing with outstanding linearity and signal fidelity.
Electrical Performance and Output Characteristics
The Bently Nevada 330103-00-05-10-02-05 provides a sensitivity of 7.87 mV/µm across its linear measurement band. Its nominal gap voltage stabilizes 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 movements and rapid transient vibrations. Additionally, the integrated EMI shielding minimizes electrical interference from variable-frequency drives and adjacent machinery.
Mechanical Design and Installation Features
The probe housing employs a 3/8-24 UNF-2A thread for straightforward 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 durable coaxial connector. This cable length simplifies routing through complex equipment layouts. Furthermore, the single internal coil assembly generates a stable high-frequency field for consistent gap voltage readings.
