BENTLY NEVADA 330780-50-05 3300 XL 11mm Proximitor Sensor

Description

The BENTLY NEVADA 330780-50-05 is part of the 3300 XL 11mm Proximitor Sensor System, designed for non-contact displacement and vibration measurement. It operates across a frequency range of 0 to 8kHz, with core applications including radial vibration and displacement, axial displacement, and key phase measurement for rotating industrial equipment. This panel-mounted unit features a total system length of 5.0 meters (16.4 feet), as indicated by the model’s “50” designation.

It receives signals from non-contact 3300 XL 11mm eddy current probes and extension cables, converting them into voltage signals proportional to the distance between the probe tip and monitored surface. The unit requires an input voltage range of -17.5Vdc to -26Vdc, with a maximum current draw of 12mA when no barrier is used. Its measurement linear range starts at approximately 0.5mm (20 mils) from the target surface, extending to 4.5mm (180 mils), with a sensitivity of 3.94V/mm (100mV/mil) ±10% measured in 0.5mm (20 mil) increments across the 4.0mm linear span. The system offers strong radio interference resistance, and is suitable for use in power plants, metallurgy, petroleum, and chemical processing industries for critical machinery condition monitoring.
