MMF > High Sensitivity

High Sensitivity Accelerometers: 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.
Model KB12(VD) has an unusual design featuring air damping for a low resonance peak and friction coupling for overload protection.
