Product Introduction
The Bently Nevada 330906-02-12-05-02-00 is a high-precision 3300 NSv (Narrow Side View) reverse-mount proximity probe designed for shaft vibration and position monitoring in tight or restricted installation environments. Unlike standard forward-mount probes, this reverse-mount configuration allows the sensor tip to be positioned facing backward relative to the mounting point, enabling measurements in applications where space constraints or machinery geometry prevent conventional probe installation.
With a total length of 0.5 meters and a durable construction, this probe is engineered to provide consistent and accurate eddy current sensing performance for industrial rotating equipment. Its weight of 0.453 kg reflects the robust materials and reinforced design intended for long-term reliability under harsh operating conditions. The probe is compatible with Bently Nevada 3300 NSv driver systems and adheres to industry standards, making it a preferred choice in sectors like oil & gas, power generation, petrochemical, and heavy industry.
