Acceleration Sensors

Precise measurement of acceleration, vibration and shock

Platform Acceleration Sensorsolution Althen Sensors

Acceleration Sensors for Measurement & Monitoring

Acceleration sensors or accelerometers let you make precise measurements of vibration or shock for a variety of applications. They are used to measure vibration, shock, displacement, velocity, inclination and tilt. Our accelerometers are based on several different technologies and include piezoelectric, strain gauges, MEMS, and capacitive sensors.

All sensors are highly resistant against shock and vibration and are suitable for a wide range of purposes. They operate at frequencies of up to 25,000 Hz, with measurement ranges between ±0.25 g and ±70,000 g, and can be deployed in temperatures ranging from -40°C to +140°C.

Wireless IoT Acceleration Measurement

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.

Measure and Monitor Steady and Unsteady Acceleration

Just as there are many different applications for accelerometers, there are many different ways to build them: We offer acceleration sensors with piezoelectric, piezoresistive, strain gauge, MEMS, and capacitive measurement technology. In order to pick the right accelerometer, you should first analyze the conditions and parameters under which the sensor will be deployed. Our experts at Althen are happy to give extensive, independent advice – and help you find exactly the right accelerometer for your task.

Our acceleration sensors are available with integrated or external electronics. We can also integrate our sensors into your application for you. Althen is your competent partner for accelerometers for any of the following fields:

  • Submersible and naval installations
  • Transport measurements
  • Bridge and tunnel construction, Structural monitoring
  • Environmental monitoring
  • Aviation testing, Explosion testing
  • Biomechanical studies
  • SAE and racing crash tests

We offer a special range of Euro-NCAP certified, miniature accelerometers for the automotive industry. In addition to NCAP certification, part of the portfolio is also certified for the use in crash tests according to SAE J211/J2570, ISO 6487 and World SID. Our sensors offer single- and multi- axis measurements. You can choose from versions with integrated measurement amplifiers or full open Wheatstone bridges. The sensors can be mounted by glue joints or using fasteners.

In addition to sensors with directly mounted, shielded, low-noise cables, we also offer models with plug connectors. These are particularly suited for mechanically critical positions where the cables are under great stress (such as on test dummies) and frequently need to be replaced.

But you can not only replace the cables. Several sensors for multi-axis measurement can also be repaired should a measurement axis get damaged from excessive load. The casings are available in stainless steel, aluminum, or fully welded titanium versions.

Simply get in touch and let us know your requirements.

Applications with Acceleration Sensors

Would you like to get to know our products in practice? Take a look at these interesting projects from our customers:

How Accelerometers Work

Piezoelectric Acceleration Sensors (AC Response)

Under acceleration, the seismic mass of the sensor 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.

Capacitive Acceleration Sensors (DC Response)

Capacitive acceleration sensors are based on changes in the electrical capacity of the seismic mass under acceleration. This is a widespread technology commonly used applications such as airbags and mobile devices. Our capacitive acceleration sensors are manufactured using microelectromechanical systems (MEMS) technology. Our high-end silicon MEMS accelerometers in instrumentation quality are resistant against prestress and produce very little noise.
