High Sensitivity Accelerometers
Metra Mess- und Frequenztechnik in Radebeul e.K.
The piezoelectric accelerometers on this page are intended for the measurement of lowest vibrations. Typical fields of application include the monitoring of buildings, dams, bridges, oil platforms and pipelines. These sensors are often called seismic accelerometers because they are used to monitor construction activity, volcanoes and earthquakes. Their high sensitivity is achieved -unlike other high sensitivity accelerometers- by the sensing element itself and not by internal amplification. From this results highest resolution and lowest noise.

PC Vibration Measuring System VibroMetra
Metra Mess- und Frequenztechnik in Radebeul e.K.
*The system was designed for typical tasks of vibration measurement. No ballast by unwanted functionality. *The system is modular making it upgradeable and particularly economic with fewer channels.*The necessary hardware is very compact which makes it particularly suited for mobile use.*Short installation and training time. After a few minutes you may start with the first measurement.*Off-line measurement: VibroMetra permanently saves the raw data stream of the sensor signal in the background. By this means you may analyze your measurement later again with other settings or other software instruments.*Data export as graphics, text or binary file

Universal Accelerometers
Metra Mess- und Frequenztechnik in Radebeul e.K.
There are models with charge output and with IEPE compatible voltage output. The transducers of KS series have a shear type sensing element making them less susceptible to thermal transients and base strain. The accelerometers of KD series have a compression type sensing element combining rugged design, precision and low cost.
