Tip of the Month:
ISO 17025 Proficiency Testing
|
Moving into Quarter 4 of this year, remember that any ISO 17025-accredited providers should have already conducted annual proficiency testing, or should be scheduling it soon.

University of Buffalo Calibrates Seismic Sensors for Earthquake Simulation
By Kacey King Redmond, Marketing Communications
|
The University of Buffalo (UB) supports both research and commercial projects focused on structural engineering. UB purchased a low-frequency shaker and was trying to develop its own control algorithms and report processing for low-frequency calibration of seismic sensors. UB gets most of its commercial work by word-of-mouth. Its main work is with customers who are seeking seismic certification ...

Blast from the Past: Improved Low-Frequency
Accelerometer Calibration
|
Discussion about accelerometer calibration often refers  primarily to the measurement of voltage sensitivity across a frequency range. The most common way to calibrate accelerometer sensitivity is by comparison to a reference transducer, generally another accelerometer designed to have stable low noise sensitivity in the conditions of calibration. Comparison methods are performed by back-to-back measurements, typically as a stepped sinusoid across an appropriate frequency range. The Sensor Under Test (SUT) is mounted...
