Accelerometers are used in so many everyday devices but how many of us actually know what they do? Read below to get a quick overview of what accelerometers do and how calibration plays a pivotal role in there functioning.
An accelerometer measures vibration and acceleration. The force caused by vibration or changes in motion cause the 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 smart phones use accelerometers. Accelerometers are found in the guidance systems for aircrafts and missiles, drones use them for flight stabilization, they’re even in your car.
One of the most important uses of accelerometers is in industrial hygiene equipment that keeps people safe in the workplace. Hand and arm vibration testing during the use of manually operated jackhammers and gripping vibrating machinery can reveal problems that can cause medical issues in workers.
If your accelerometer is not calibrated, it may lead to catastrophic failure in your equipment. When the accelerometer in industrial hygiene equipment is not calibrated it can 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 10Hz to 10kHz. These calibrations are NIST traceable which ensures an extremely high standard of calibration.
