Miniature Accelerometers
-
Metra Mess- und Frequenztechnik in Radebeul e.K.
These piezoelectric accelerometers are particularly suited for small and light test objects. Of particular advantage may also be their high resonant frequencies. Due to the piezoelectric principle with its wide dynamic range both high acceleration and lowest vibration can be measured with the same sensor.

Industrial Accelerometers
-
Metra Mess- und Frequenztechnik in Radebeul e.K.
These piezoelectric vibration transducers have been designed for application under rough environmental conditions. They are dust and water protected. Their mounting base is insulated to avoid ground loops which may cause errors, particularly, close to big machinery.

Event Messengers
-
Metra Mess- und Frequenztechnik in Radebeul e.K.
When analyzing vibrations with VibroMetra, the measured data is displayed optically in the instruments first, or data is saved if required. Event messengers extend the instrument's possibilities of transferring data by additional outputs.

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. 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.
