Product Introduction
The Bently Nevada 330906-02-12-05-02-CN 3300 NSv Reverse Mount Probe is a high-precision eddy current proximity sensor designed for measuring the dynamic and static position of machine shafts and rotors in industrial rotating equipment. As part of the 3300 NSv (Narrow Signal variant) system, this probe is specifically optimized for small or compact machines, providing reliable displacement measurements where standard probes cannot be easily installed.
This reverse mount version allows the sensing element to be installed from the rear of the mounting surface, making it ideal for applications where direct forward access is limited or restricted. With its 0.5-meter total cable length, the probe ensures minimal signal loss while maintaining high accuracy and stability. Constructed with stainless steel housing and a shielded cable, it offers exceptional resistance to electromagnetic interference (EMI), vibration, and harsh industrial environments.
Engineered for precise shaft vibration and position monitoring, the 330906-02-12-05-02-CN probe integrates seamlessly with Bently Nevada 3300 NSv Proximitor® sensors and monitoring systems, ensuring consistent performance in turbines, compressors, motors, and pumps.
