Bently Nevada 330500-04-01 Velomitor Piezo-velocity Sensor

Description

The 330500-04-01 Velomitor Piezo-velocity Sensor is a specialized piezoelectric accelerometer designed for measuring absolute casing, housing, or structural vibration. This configuration features a 1/4-20 UNC mounting thread (Option 04) and CSA/US/C agency approvals (Option 01). The sensor utilizes a solid-state, integrated design with no moving parts, allowing for flexible mounting orientations including vertical, horizontal, and angled positions without risk of mechanical wear or degradation.

Used extensively in industrial machinery protection, the 330500 provides a velocity-based output signal representing absolute vibration. Unlike traditional moving-coil sensors, this piezo-velocity technology is immune to the mechanical limitations associated with internal wear, ensuring long-term operational stability in demanding monitoring environments. It is intended for mounting directly to bearing housings or machine casings to capture vibration data necessary for identifying common machinery malfunctions such as unbalance and misalignment.
