Bently Nevada 330180-90-CN | 3300 XL Proximitor Sensor

8 mm Proximitor for Eddy Current Probe Systems

The Bently Nevada 330180-90-CN 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 for monitoring systems. It provides reliable shaft displacement data for turbines, compressors, and large motor-generator sets.

This Proximitor operates with a matching 8 mm probe and extends the cable run up to 300 meters. A factory-matched configuration ensures consistent linearity without requiring field calibration. The device outputs a -1 to -21 VDC signal for direct connection to Bently Nevada monitors.
