330850-90-CN Bently Nevada 25 mm Proximitor Sensor
330850-90-CN
330850-90-CN is a Bently Nevada 3300 XL 25 mm Proximitor Sensor configured for a 9 m transducer system with panel mounting and the China country-specific hazardous-area option. 330850-90-CN accepts one matched 3300 XL 25 mm proximity probe and the compatible cable path. 330850-90-CN is the signal-conditioning component, not a complete transducer system.
Scope note: 330850-90-CN identifies 3300 XL 25 mm Proximitor Sensor; signal conditioner only. Complete-system performance is labeled separately and does not apply to 330850-90-CN alone.
