Description

The Bently Nevada 330780-91-00 serves as a core component for advanced industrial protection systems. This Proximitor sensor specifically supports the 3300 XL 11 mm proximity probe series. It effectively measures shaft vibration and axial position in critical rotating equipment. Furthermore, the 9.0-meter system length provides flexibility for diverse installation requirements. The device ensures accurate data delivery for turbomachinery monitoring in power and oil sectors. Reliability remains a hallmark of this USA-manufactured sensing technology.

Technical Performance and Electrical Stability

This sensor maintains exceptional signal integrity under varying power conditions. It operates within a standard input range of -17.5 Vdc to -26 Vdc. Additionally, the unit exhibits minimal sensitivity to voltage fluctuations during operation. The output signal changes less than 2 mV for every volt of input variation. This stability ensures precise measurements even during minor power inconsistencies. Moreover, the 12 mA maximum current draw promotes efficient energy usage in large-scale monitoring arrays.

Key Hardware Characteristics
