velocity seismic vibration prop calibration method
Select a Calibration Source:
Choose a known, stable vibration source. This could be a calibrated shaker table or a mechanical vibration source with a known frequency and amplitude.
Install the Sensor:
Mount the velocity seismic sensor in the desired location where it will be used for measurements. Ensure that it is securely attached and aligned properly.
Set Up the Calibration Equipment:
Connect the seismic sensor to the calibration equipment. If using a shaker table, ensure it's properly set up and connected to a signal generator.
Generate Vibration Signals:
Generate a range of vibration signals with known frequencies and amplitudes. This should cover the expected operating range of the sensor.
Measure and Record Responses:
Record the sensor responses to the generated vibrations. Measure the output signals of the sensor for each frequency and amplitude setting.
Compare Measurements:
Compare the measured responses of the sensor with the known input values. This helps identify any discrepancies and allows for calibration adjustments.
Adjust Calibration Settings:
If discrepancies are found, adjust the calibration settings of the sensor. This may involve adjusting gain, sensitivity, or other relevant parameters to align the sensor's output with the known input.
Repeat if Necessary:
Repeat the calibration process until the sensor consistently provides accurate and reliable measurements across the desired range.
Documentation:
Document the calibration results, including any adjustments made to the sensor. This documentation is crucial for maintaining a record of the sensor's calibration history.
Regular Maintenance:
Schedule regular maintenance and recalibration to ensure that the sensor continues to provide accurate measurements over time.
Always follow the specific calibration procedures recommended by the sensor manufacturer, as details may vary depending on the model and technology used
