YD-12 Automatic Vibration Calibrator

YD-12 uses a 7.5-inch TFT touchscreen with 640 × 480 resolution. Its internal acquisition and communication board uses a 500 ksps, 16-bit A/D converter. An ARM9 embedded system processes absolute vibration data in real time and controls calibration.

The introduction describes uploading data to a PC or laptop over RJ-45 for offline printing of sensor linearity data, amplitude-frequency data and their curves. The specification table instead lists USB transfer and automatic testing while connected. The relationship between these interfaces is unconfirmed.

The catalog lists the following velocity-sensor families as calibration applications: Bently BN9200/74712/330500/190501, epro PR9266/9268, Schenck VS-069/169 and VS-068/168, and Shinkawa CV-851/852. It also names BN330400 and Entek9200 alongside acceleration, velocity and eddy current sensors. Confirm the connection and calibration arrangement for the exact sensor configuration.

The catalog requires a protective-earth connection for the three-wire 220 VAC supply.

The introduction specifies RJ-45 upload and the technical table specifies USB upload. Both statements are retained. This reference does not establish whether both are fitted, optional or associated with different configurations.
