Bently Nevada 330980-71-00 | 3300 XL Proximitor Sensor

8 mm Proximitor with 7-Button Interface for 3300 XL Systems

The Bently Nevada 330980-71-00 functions as the signal conditioning element within the 3300 XL proximity measurement system. This device converts the eddy current probe’s RF signal into a proportional DC voltage. It provides reliable shaft displacement data for turbines, compressors, and motor-generator sets.

This Proximitor operates with a matching 8 mm probe and includes a 7-button interface for convenient configuration. A factory-matched configuration ensures consistent linearity without requiring field calibration. The device outputs a -1 to -21 VDC signal for direct connection to monitoring systems.
