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

Description

The 330500-01-CN Velomitor Piezo-velocity Sensor provides continuous casing vibration measurement for rotating machinery applications. This sensor incorporates a piezoelectric acceleration sensing element with integrated signal conditioning electronics to produce an output proportional to vibration velocity, effectively bridging the gap between accelerometers and velocity sensors. The -CN suffix indicates this unit includes the China hazardous area approval package, incorporating NEPSI and CCC certifications required for regional compliance.

This 330500 model features an integrated sensor design that eliminates the need for separate signal conditioners, simplifying installation on balance-of-plant machinery such as fans, pumps, motors, and gearboxes. The -01 configuration designates the standard mounting and output interface, providing a consistent signal for vibration monitoring systems. The device operates across a wide frequency range and temperature spectrum, ensuring accurate casing vibration data for machinery protection.

Installation Guidelines

Ensure the sensor is mounted on a rigid part of the machine casing to accurately capture vibration. Proper torque application during mounting is critical for maintaining frequency response consistency. Ensure the cable is properly routed and secured to prevent mechanical strain on the connector. For hazardous area installations, confirm that the system wiring adheres to local safety standards for NEPSI and CCC installations as specified by the -CN certification package.

Compliance and Certifications

• NEPSI (China hazardous area approval)
• CCC (China Compulsory Certification)
• Applicable CE directives for machinery and electromagnetic compatibility
