Product Overview

The Bently Nevada 330500-03-04 is a piezo-velocity vibration sensor used to measure absolute vibration on machine casings, bearing housings, and structural members. The sensor converts vibration velocity into a conditioned electrical output suitable for vibration monitoring and machinery protection systems. Its solid-state sensing element with integrated electronics is designed for stable operation in continuous-duty industrial environments.

This sensor is applied where casing vibration is the preferred measurement, such as on pumps, motors, fans, compressors, gearboxes, and auxiliary skids. Correct mounting on a rigid surface is essential so the measured vibration accurately represents machine condition rather than local structural noise.
