What Does an Accelerometer Do...?

What does an accelerometer do and why is it so important to keep it calibrated?

So many everyday devices are equipped with accelerometers, but how many of us actually know what they do or even what an accelerometer is? Read below to get a quick overview of what accelerometers do and how calibration plays a pivotal role in their functioning.

An accelerometer measures vibration and acceleration. The force caused by vibration or changes in motion cause mass to squeeze and create an electrical charge that is based on the force exerted upon it.

Accelerometers are found in many devices. You probably own something that uses an accelerometer. In fact, all smartphones use accelerometers. Guidance systems for aircrafts, missiles and even vehicle navigation systems all rely on these devices. Drones also use them for flight stabilization.

One of the most important roles an accelerometer plays is working inside industrial hygiene equipment. Industrial hygiene instruments are responsible for keeping people safe at work by measuring various elements within a variety of occupational environments. Workers using vibrating machinery such as jackhammers can develop hand-arm vibration syndrome from over-exposure. Accelerometers are utilized by hygienists to measure the vibration level coming from these instruments.

If your accelerometer is not calibrated, it may lead to incorrect readings which could result in workplace injury.

CIH Equipment uses the Bouche Labs Model 5000c Comparison-Accelerometer Calibration System using a Bouche Labs Model 1000A Primary Vibration Standard Shaker with a range of 10 Hz to 10 kHz. These calibrations are NIST traceable which ensures an extremely high standard of calibration.
