Independent vibrator test system

Because vibrator controller QC systems use the same hardware and software as the vibrator control systems they are testing, a totally independent cross-check is the only way to ensure correct vibrator operation.

Verif-i Sandwich Box vibrator test system - key features

Ease of use

Verif-i’s Sandwich Box vibrator test system can measure all aspects of vibrator performance in one simple operation, using magnetically-mounted accelerometers coupled with our dedicated software.

The system allows a comprehensive evaluation of vibrator operation without specialised knowledge of vibrators or computers. The software features an intuitive user interface and automated data processing. Only one 25 metre cable is needed to connect the vibrator to the acquisition unit.

A real time display of accelerometer and reference signals during the sweep highlights any problems during data acquisition. Analysis and display of all plots at end of sweep is accomplished with a single mouse click.

Functionality

Supplied complete with two calibrated 30 mV/g accelerometers, AC/DC power supply and all required cables, the acquisition unit is housed in a rugged Peli box and connects to a Windows PC via the USB port.

The unit uses eight Sigma Delta converters for zero sample skew data. The gain of each channel is automatically set by means of a test sweep to maximize dynamic range of the acquired signals. Raw data can be saved to the PC’s hard drive in SEG-D format files for post-processing and results can be saved as graphics files.

All acquired signals, including a weighted sum force analogue signal, are buffered and may be connected to a seismic instrument for independent recording.

There are eight channels which may be configured as voltage inputs or for use with accelerometers.
