Features:

  • Piezoelectric Accelerometer with Embedded Integrated Electronics
  • Solid-State Design with No Moving Parts for Long-Term Reliability
  • Configurable Mounting Options and Hazardous Area Certification
The 330500-04-02 operates as a specialized Velomitor Piezo-velocity Sensor, providing reliable absolute vibration measurement (relative to free space) for bearing housing, casing, or structural monitoring applications. It continuously converts mechanical vibration into electrical signals through its piezoelectric sensing element and processes these signals through embedded integrated electronics to produce accurate velocity output. Seamless orientation flexibility is standard with the 330500-04-02, as it can be mounted vertically, horizontally, or at any angle without performance degradation. The 330500-04-02 has made improvements in several areas over previous velocity sensor designs in addition to incorporating solid-state electronics that eliminate mechanical wear and degradation.

The 330500-04-02 provides essential vibration measurement functions critical to machinery protection systems, and is a key component of the monitoring path, directly affecting the proper detection of rotor-related malfunctions such as unbalance and misalignment. Proper installation of the 330500-04-02 on bearing housing or machine casing is required for effective operation. The 330500-04-02 occupies minimal mounting space and is always positioned to ensure optimal transmission of rotor vibration to the transducer location.

For displacement measurement applications, the 330500-04-02 requires careful consideration of electrical noise management. In addition to standard velocity output operation, the integration process also performs signal conditioning. The 330500-04-02 displacement configuration executes measurement using the internal circuitry specified in the transducer options. Using this method, the system continually monitors signal integrity. If the system detects that electrical noise from interference and the transducer circuit is being amplified during integration, it may degrade performance of the 330500-04-02 transducer and produce inaccurate displacement data, requiring proper grounding and shielding practices.

The 330500-04-02 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 330500-04-02 Velomitor Piezo-velocity Sensor is designed to measure absolute (relative to free space) bearing housing, casing, or structural vibration in industrial machinery. This specialized piezoelectric accelerometer incorporates embedded integrated electronics in a solid-state design, ensuring reliable performance without mechanical degradation or wear. Because the 330500-04-02 incorporates solid-state electronics and has no moving parts, it can be mounted vertically, horizontally, or at any other angle of orientation, providing flexibility for various installation requirements. This 330500-04-02 sensor is specifically configured with a 1/4 - 20 UNC Mounting Thread Adaptor and carries ATEX (European) Agency Approval, making it suitable for hazardous area applications in European industrial environments.

This 330500-04-02 sensor is specifically designed for machinery protection applications where accurate vibration monitoring is critical. Most common machine malfunctions such as unbalance, misalignment, and other rotor-related issues originate as an increase or change in rotor vibration. For any individual casing measurement to be effective for overall machine protection, the system must continually transmit a significant amount of rotor vibration to the machine casing or the mounting location of the transducer. The 330500-04-02 excels in these applications by providing consistent, high-quality vibration data that enables early detection of developing machinery problems. Careful installation of the 330500-04-02 on the bearing housing or machine casing is essential, as improper installation may decrease the transducer amplitude and frequency response and/or generate false signals that do not represent actual vibration conditions.

When integrating the 330500-04-02 Velomitor output to measure displacement, special consideration must be given to electrical noise management. Electrical noise from interference and the transducer circuit can be amplified during integration, potentially degrading the performance of 330500-04-02 transducers and producing inaccurate displacement data. Proper grounding and shielding practices should be followed to maintain the measurement integrity of the 330500-04-02 in displacement monitoring applications.
