Analog Devices Inc. ADXL100x MEMS Accelerometers

Analog Devices Inc. ADXL100x MEMS Accelerometers deliver high-resolution vibration measurements for industrial-condition monitoring applications. The accelerometers are available with full-scale ranges of ±100g (ADXL1001), ±50g (ADXL1002), and ±500g (ADXL1004).

The ADXL100x Accelerometers offer a range of ultra-low noise densities from 25μg/√Hz to 125μg/√Hz, over an extended frequency range. These devices exhibit stable and repeatable sensitivity and are immune to external shocks up to 10,000g.

Analog Devices Inc. ADXL100x MEMS Accelerometers include an integrated full electrostatic Self Test (ST) function and an OverRange (OR) indicator. The ST function and OR indicator enable advanced system-level features useful for embedded applications. The accelerometers also facilitate wireless sensing product design with their low-power 3.3V to 5.25V single-supply operation.

Available in a 5mm x 5mm x 1.80mm LFCSP package, the ADXL100x MEMS Accelerometers are rated for an industrial -40°C to +125°C temperature range.

Choosing the Right Accelerometer for Predictive Maintenance
Monitoring a machine’s health status enables predictive maintenance, allowing industries to anticipate breakdowns and realize substantial operational savings and downtime. To determine when it is the right time to trigger a maintenance operation, the manufacturer uses parameters such as vibration, noise, and temperature measurements. In a rotating machine (engine, generator, etc.), an abnormal vibration can signify a faulty ball bearing, axle misalignment, imbalance, or excessive looseness. Avoid being caught off guard and detect the first signs of an anomaly with a low noise, high bandwidth accelerometer.

Choosing The Most Suitable Predictive Maintenance Sensor
Predictive maintenance (PdM) involves techniques such as Condition-based monitoring (CbM), machine learning, and analytics to predict upcoming machine or asset failures. When monitoring the health of a machine, it is critically important to select the most suitable sensors to ensure faults can be detected, diagnosed, and even predicted.
