Accelerometers and Acoustic Emission Sensors from Kistler

Kistler’s product portfolio includes a variety of single and triaxial accelerometers that can consistently endure the most demanding applications while providing reliable results.

Very high frequency activity is routinely measured with one of the several miniature piezoelectric accelerometers. Typical application examples for these sensors are environmental testing in space loads, Noise Vibration & Harshness (NVH) in automotive or modal analysis.

Whereas for applications where static or low frequency activity is of interest MEMS Variable Capacitance accelerometers are the right choice. MEMS Variable Capacitance accelerometers might be used for ultra-low frequency measurements such as automotive and railway durability testing, in flight flutter testing in aviation, vibration monitoring in railway or bridge structural monitoring for example.

With Acoustic Emission sensors the measurement of acoustic waves on metallic surfaces up to 1MHz are possible. These sensors can be used for non-destructive testing or permanent online monitoring.

Additional specific products such as rotational accelerometers for measurements on an oscillating specimen, impedance heads and impact hammers for modal analysis are also available.
