Product Overview

The Bently Nevada 330500-01-04 is a Velomitor piezo-velocity sensor used to measure absolute casing or bearing-housing vibration on rotating and reciprocating machinery. The device outputs a velocity-proportional electrical signal suitable for connection to monitoring and protection systems, supporting continuous condition monitoring and vibration-based maintenance practices.

This sensor uses a solid-state piezoelectric sensing element with integrated electronics. With no moving parts, it is well-suited for long-term service where mechanical wear, contamination, and sustained vibration exposure can reduce the stability of traditional velocity pickups. It can be installed in multiple orientations to fit common field mounting constraints.

Hardware Parameters

Implementation notes

• Verify input requirements (bias, power, and connector style) on the receiving monitoring module before installation.

• Signal quality depends on mounting stiffness, surface preparation, and correct torque per site practices.

Industrial Applications

• Bearing housing and casing vibration measurement for pumps, motors, fans, blowers, and gearboxes

• Machinery protection and condition monitoring systems using velocity as the preferred parameter

• Predictive maintenance programs in power generation, oil and gas, petrochemical, and heavy manufacturing sites

• Installations where rugged solid-state construction is required due to high vibration or limited access for frequent servicing
