Product Description
The part number 21000-34-05-00-030-03-02 does not conform to the standard numbering conventions of major manufacturers like Bently Nevada. Based on the structure, it is highly likely a Velocity Seismic Transmitter or a 4-20 mA Vibration Sensor. This type of device is designed to monitor the overall vibration (in velocity units like mm/s or in/s) of machine housings, structures, or bearings. It typically integrates a piezoelectric sensing element and built-in electronics to output a standard 4-20 mA signal proportional to the vibration level, which can be easily connected to PLCs, DCS, or control systems for continuous monitoring and alarm functions.
