Bently Nevada 330500-02-00 Velomitor Piezo-velocity Sensor

Description

330500-02-00 is a specialized Velomitor Piezo-velocity sensor configured with an M8x1 mounting thread adapter (Option 02) and no hazardous area agency approvals (Option 00). This transducer is engineered to measure absolute casing, bearing housing, or structural vibration on rotating machinery. As a solid-state piezoelectric accelerometer with integrated electronics, the unit provides a continuous output proportional to vibration velocity, eliminating the mechanical wear concerns associated with traditional moving-coil sensors.

The 330500 series is designed for versatile mounting orientations, including vertical, horizontal, and radial installations. This configuration, featuring the M8x1 thread, requires direct mounting to the machine casing; correct installation is critical to maintain the specified frequency response and amplitude linearity. The sensor is constructed with a 316L stainless steel, hermetically-sealed housing to withstand harsh industrial environments.

Installation Guidelines

• Ensure the sensor is mounted directly to the machine casing or bearing housing to prevent signal degradation or false readings.
• Observe the maximum mounting torque of 32-46 kg cm (24-40 in-lb).
• Verify cable routing to minimize electrical noise interference, especially if integrating the output to measure displacement.
• Ensure the mating cable connector is moisture-resistant and securely tightened to the Mil-C-5015 receptacle.

Compliance and Certifications

• EMC Directive 2014/30/EU
• RoHS Directive 2011/65/EU
• FCC Part 15
• ABS Marine Vessels
