Sampling Rate
Sampling rate is defined as the rate at which the instrument’s electronics communicate with its load sensor. A faster sampling rate more accurately captures the peak load which occurred during the test. This is especially apparent in applications where the load builds up and falls very quickly – such as the break testing of glass or ceramics. The graphs below illustrate the advantage of a fast sampling rate:
The graph at left shows that an instrument with slower sampling rate may not accurately detect the true peak. In the graph at right, the faster rate accurately captures the true peak.
Sampling Rate vs. Output RateWhile Mark-10 instruments internally sample at up to 14,000 Hz, a typical streaming output rate to MESURgauge software is approximately 25 - 50 Hz. If a faster data collection rate is required, our Series 7 force gauges and indicators can collect data at up to 14,000 Hz, store the data internally, and bulk-download the data to a PC when the test is complete.
