Description
330980-71-CN – Bently Nevada 3300 XL NSv Proximitor Sensor
Product Overview
The 330980-71-CN is a high-precision 3300 XL NSv series proximitor sensor manufactured by Bently Nevada, specially designed for non-contact vibration and position monitoring of rotating machinery. Optimized for narrow installation spaces and small-diameter shaft equipment, this inductive proximity sensor system delivers ultra-stable and high-linear measurement data. It accurately captures radial shaft vibration, axial thrust position, rotational speed and phase signals of high-speed rotating equipment. Featuring CN certification for hazardous area deployment, full industrial environmental adaptability and 7-meter complete system length design, the 330980-71-CN effectively solves inaccurate monitoring and signal loss issues of traditional sensors in limited installation space. It ensures long-term 24/7 stable condition monitoring and fault early warning for key industrial rotating machinery.
