Overview Manuals Specifications Applications Communication & Connectivity Installation & Integration

Features:

  • Piezoelectric velocity measurement with embedded integrated electronics in the 330500-06-02 solid-state design
  • Absolute vibration sensing for bearing housing, casing, and structural monitoring in rotating machinery
  • Flexible mounting orientation without mechanical wear or degradation for extended service life
The 330500-06-02 operates as the Velomitor Piezo-velocity Sensor in industrial machinery protection systems, providing accurate absolute vibration measurement to all monitoring modules within the system. It continuously senses bearing housing, casing, or structural vibration relative to free space and transmits velocity data through solid-state integrated electronics to support steady state operation of all condition monitors and protection modules. Consistent measurement accuracy is standard with the 330500-06-02, however using an optional multi-sensor configuration will allow comprehensive coverage of critical rotating equipment in the event of localized vibration anomalies.

The 330500-06-02 provides essential vibration sensing functions common to the entire machine train, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall protection system. One or more 330500-06-02 sensors are required per machine depending on the desired monitoring coverage level. The 330500-06-02 occupies minimal surface mounting space on the machine housing and is always located at the designated vibration measurement point on the bearing housing or structural member.

For comprehensive machinery protection applications, the monitoring system requires additional 330500-06-02 sensor modules installed at complementary measurement points. In addition to standard single sensor operation, the multi-point configuration also performs cross-channel vibration analysis. The monitoring system executes correlation using the internal signal processing specified in the sensor interface options. Using this method, the protection system continually monitors the health and output stability of all installed 330500-06-02 units.

The 330500-06-02 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).
