The Bently Nevada 330980-50-05 is part of the 3300 XL NSv (Narrow Side-view) Proximitor Sensor family, specifically designed for applications with space constraints or reduced mounting clearance. With a system length of 5.0 meters, this model is engineered to function in tight environments, such as small steam turbines, gearboxes, or other compact rotating equipment.
It accepts inputs from the 3300 NSv probe and extension cable, converting shaft position or vibration amplitude into a proportional voltage output. The “05” suffix indicates that this model meets stringent industrial certifications, making it suitable for hazardous or regulated environments.
