        • Piezoelectric Accelerometer with Embedded Integrated Electronics
        • Solid-State Design with No Moving Parts
        • ATEX Agency Approval for Hazardous Environments
        The 330500-01-02 Velomitor Piezo-velocity Sensor operates as a specialized vibration measurement device in industrial machinery applications, providing reliable velocity-based vibration data of bearing housing, casing, or structural vibration absolute to free space. It continuously measures vibration signals originating from common machine malfunctions such as unbalance and misalignment, and transmits this data through standard industrial interfaces to support condition monitoring and predictive maintenance systems. Seamless orientation mounting is standard with the 330500-01-02, allowing vertical, horizontal, or any angle of installation without mechanical degradation or wear. The 330500-01-02 has made improvements in several areas over previous velocity sensor designs in addition to incorporating solid-state electronics with no moving parts within the transducer housing.

        The 330500-01-02 provides essential vibration monitoring functions common to the entire machinery protection system, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall machine condition monitoring system. One or multiple 330500-01-02 sensors are required per machine depending on the desired monitoring coverage level. The 330500-01-02 occupies minimal mounting space on bearing housings or machine casings and is always located on vibration transmission paths where rotor vibration is significantly conducted to the casing.

        For comprehensive machinery protection applications, the monitoring system requires proper installation of 330500-01-02 sensor modules at critical measurement points on bearing housings or machine casings. In addition to standard signal output, the 330500-01-02 also performs continuous vibration measurement. The 330500-01-02 monitoring configuration executes measurement using the internal piezoelectric accelerometer circuitry specified in the transducer specifications. Using this method, the monitoring system continually tracks machinery vibration patterns. If the system detects electrical noise from interference and the transducer circuit when integrating output to measure displacement, it may amplify noise and degrade performance of 330500-01-02 transducers, producing inaccurate displacement data.

        The 330500-01-02 Bently Nevada Velomitor Piezo-velocity Sensor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        The 330500-01-02 Velomitor Piezo-velocity Sensor is a specialized piezoelectric accelerometer designed to measure absolute bearing housing, casing, or structural vibration in industrial machinery. This 330500-01-02 sensor incorporates embedded integrated electronics within a solid-state design, ensuring reliable performance without mechanical degradation or wear. The 330500-01-02 can be mounted vertically, horizontally, or at any angle, providing flexibility for various installation requirements. This 330500-01-02 sensor features a 1/2 - 20 UNF mounting thread adaptor and holds ATEX (European) agency approval, making it suitable for hazardous environments.

        This 330500-01-02 Velomitor Piezo-velocity Sensor is specifically designed for handling machine condition monitoring and predictive maintenance applications, addressing the critical need for accurate vibration measurement in rotating equipment. The 330500-01-02 effectively captures vibration data originating from common machine malfunctions such as unbalance and misalignment, which typically occur on the rotor and manifest as changes in rotor vibration. For the 330500-01-02 to provide effective overall machine protection, it must be installed on bearing housings or machine casings where rotor vibration is significantly transmitted, ensuring continuous monitoring of equipment health.

        When installing the 330500-01-02, proper mounting on bearing housings or machine casings is essential to maintain accurate amplitude and frequency response. Improper installation of the 330500-01-02 may result in decreased signal quality or generation of false readings that do not represent actual vibration conditions. Additionally, when integrating the 330500-01-02 output for displacement measurement, users should be aware that electrical noise from interference and the transducer circuit may be amplified, potentially degrading performance and producing inaccurate displacement data. The 330500-01-02 is ideal for applications requiring reliable velocity-based vibration monitoring in critical rotating machinery across industrial facilities.
