Product Introduction
The Bently Nevada 330980-50 3300 XL NSv Proximitor Sensor is part of the trusted 3300 XL series designed by GE Bently Nevada, a globally recognized leader in machinery condition monitoring and protection. This sensor is specifically engineered for applications requiring small target proximity measurements, particularly in areas where space is limited or where the target materials are non-standard. It forms part of a complete proximity measurement system when used with matching probe and extension cable.
This model offers a linear output over a specific range for precise position and vibration measurements and is optimized for narrow target surfaces, making it ideal for use on smaller machinery such as motors, pumps, and gearboxes where standard sensors cannot be applied effectively.
