Bently Nevada 330180-50-00 Proximitor Sensor, a key member of the 3300 XL series, stands out for its (excellent) performance. It receives signals from specified 3300-series probes and extension cables, outputting voltages proportional to the distance between the probe tip and the measured conductive surface. This enables precise measurement of both static positions and dynamic vibrations. With a rugged and reliable design, the sensor is highly immune to radio frequency interference, adapting to various harsh environments. Its flexible installation supports high-density DIN rail or traditional panel mounting, providing a stable and efficient solution for industrial equipment condition monitoring.

Maximum length from 3300 XL proximitor to monitor: 305m (1000ft).
Linear Range: 2mm (80 mils), starting ~0.25mm (10 mils) from target surface, spanning 0.25-2.3mm (10-90 mils, approx. -1 to -17Vdc).
Recommended Gap Setting: 1.27mm (50 mils).
Mounting:
Compact design supports:
High-density DIN rail mounting.
Traditional panel mounting.
Enhanced RFI/EMI immunity meets European EMC standards without special installation considerations. SpringLoc terminal strips enable tool-free, secure field wiring.
System Overview:
The 3300 XL 8mm proximity sensor system (probe, extension cable, and proximitor) provides an output voltage proportional to the distance between the probe tip and conductive target. It measures both static (position) and dynamic (vibration) values, ideal for:
Vibration and position monitoring in fluid-film bearing machinery.
Phase reference and speed measurement applications.
