Description
1. Product Title
Bently Nevada 330100-90-01 – 3300 XL Proximitor® Sensor System
2. Product Overview
The 330100-90-01 is an enhanced variant of the 3300 XL Proximitor® sensor assembly from Bently Nevada’s proximity transducer lineup, optimized for non-contact vibration, position, and speed measurements in rotating equipment. This eddy current sensor system outputs voltage proportional to probe-to-shaft gap, supporting both static position monitoring and dynamic vibration analysis in fluid-film bearing machines. It resolves key predictive maintenance challenges by delivering high-fidelity signals resistant to electrical noise and harsh conditions, compatible with 3300/3500 monitoring racks. With a standard 9-meter cable length like its predecessor 330100-90-00, the <span style=”color: blue;”>Bently Nevada 330100-90-01</span> offers improved environmental sealing (NSv designation) for superior performance in demanding applications.
