The Bently Nevada 330103-00-05-90-02-00 is an 8 mm eddy current proximity probe designed for vibration and position monitoring in industrial machinery. It interfaces with the Bently Nevada 3500 System to provide real-time shaft displacement measurements with a linear voltage output proportional to target distance. The probe operates on electromagnetic induction principles, generating a high-frequency field to detect conductive target material. Its stainless steel construction ensures durability in harsh environments. The probe is calibrated for optimal performance with Bently Nevada preamplifiers and meets API 670 standards for machinery protection.

Designed for critical asset monitoring in Oil & Gas turbines, power generation equipment, and high-speed compressors. The probe maintains ±1% linearity within its specified measurement range and demonstrates MTBF exceeding 100,000 hours in continuous operation. Its IP67-rated housing resists moisture and particulate ingress. The 3300 XL series probes integrate with Bently Nevada condition monitoring systems for predictive maintenance applications.
Q: What is the required gap voltage during probe installation?
A: Set the gap voltage to -10 VDC ±0.5 V when the probe is at its nominal operating position from the target.
Q: Can this probe replace older 5 mm Bently Nevada probes without system recalibration?
A: No. The 8 mm probe requires recalibration of the monitoring system due to different sensitivity characteristics. Verify compatibility with existing preamplifiers before installation.
