Applications for Acceleration Sensors
- Automotive industry/racing (transmission testing, crash testing, brake controls, engine diagnostics, etc.)
- Construction (geophysical and seismic measurements, bridge and tunnel construction, crane controls, etc.)
- Aerospace (flight simulation etc.)
- Sports and entertainment (theme park rides etc.)
Abnormal accelerations, vibrations or high temperatures give early signs of machine failure due component imbalance, misalignment, wear or improper use of equipment. Those can be now effortlessly identified without manual measurements or expensive wired equipment to increase machine uptime and extend mean time between failures.
Together with our technology partner Treon we supply a smart industrial IoT measurement solution for condition monitoring applications. The system consists of wireless battery powered industrial sensor nodes and a gateway for communication to transmit data to the cloud.

Triaxial Accelerometer in HIC Impact Tester
To create a perfect playing field, it needs to have the right bounce, damp, level, profile and many more factors. A HIC Impact Tester with a triaxial accelerometer determines the HIC and G performance (acceleration due to gravity) by dropping the HIC head from a selected height.
How Accelerometers Work
在加速度下,地震传感器的质量causes a change in electrical charge in the piezo element, which can be read out as a charge Q that is proportional to the acceleration. Piezoelectric elements behave like a capacitor providing voltage at a set internal resistance. With an optional charge amplifier integrated in the sensor casing (IEPE interface), the output is converted into a voltage.
Piezoresistive Acceleration Sensors (DC Response)
Direct current acceleration sensors are also called piezoresistive acceleration sensors. A piezoresistive accelerometer is based on changes in electrical resistance in a strain gauge (part of the sensor’s seismic system). To compensate for temperature fluctuations, these sensors require an additional internal or external temperature compensation for their output. Modern piezoresistive sensors accomplish this using special integrated circuits for all forms of on-board signal conditioning as well as on-site temperature compensation. You can either use these sensors with conventional glued-on strain gauges or opt for microelectromechanical systems (MEMS) technology instead.
