The Bently Nevada 3300 XL Proximitor Sensor acts as the sophisticated signal processor within an eddy current transducer system. Its architecture features advanced circuitry that generates a Radio Frequency (RF) signal to the 3300 XL proximity probe and demodulates the return signal into a linear voltage output. Key technical characteristics include high interchangeable accuracy, excellent RFI/EMI immunity, and a design that eliminates the need for field calibration. Functionally, the Proximitor sensor provides a calibrated output proportional to the distance between the probe tip and the target material. This allows for precise measurement of static gap and dynamic vibration, making it a critical component for monitoring fluid-film bearing performance in high-speed rotating equipment when integrated with 3300 XL extension cables.
