Bently Nevada 123616-01 3300 XL NSv Proximitor Sensor
The Bently Nevada 123616-01 is a high-precision 3300 XL NSv Proximitor Sensor designed for small-diameter shaft monitoring and confined spaces. It provides a linear voltage output for vibration and position measurement, offering superior noise rejection and temperature stability for critical machinery protection in 3500 series systems.
Product Description
The Bently Nevada 123616-01 operates as a core component of the 3300 XL NSv (Non-Standard vent) Proximity Transducer System. This Proximitor Sensor functions by converting the signal from an eddy current probe into a usable voltage output that is directly proportional to the distance between the probe tip and the target metal surface. Because industrial machinery often features tight installation constraints or small-diameter shafts, the 123616-01 utilizes a specialized design that minimizes the “side-view” effect, allowing for accurate vibration and position measurements where standard sensors might fail.
Furthermore, this module excels in measuring fluid-film bearings on high-speed turbines, compressors, and pumps. It effectively handles targets as small as 6.35 mm (0.25 in) in diameter, making it indispensable for monitoring centrifugal machinery with restricted access. Since the 123616-01 provides superior temperature stability and high-frequency response, it ensures that the 3500 Monitoring System receives precise data for early fault detection. Its ruggedized housing resists chemical exposure and mechanical stress, maintaining the integrity of critical machinery protection loops in demanding petrochemical and power generation environments.
