Accelerometer
EMIC offers many kinds of accelerometers available for various vibration measurements. They are a ultra small light weight accelerometer for highly precise measurement, a special tri-axial accelerometer for simultaneously measuring a vibration in three orthogonal axes, a large output accelerometer for measuring an earthquake and a suitable accelerometer for measuring and analyzing a building structure.

Earthquake Early Warning
MyShake
UC Berkeley Seismological Laboratory
MyShake is a free app for Android phones that has the ability to recognize earthquake shaking using the sensors in every smartphone. The app runs “silently” in the background on your phone using very little power – just like the step-tracking fitness apps. When the shaking fits the vibrational profile of an earthquake, the app sends the anonymous information to our central system that confirms the location and magnitude of the quake.

Emergency Alternative EDFA system
Telecommunication systems are vitally important in our daily lives, even more so during the rescue and recovery processes upon natural disasters, such as the earthquake hitting the east-coast of Japan in 2011. The deadly earthquake rattled the nation coast before unleashing a deadly tsunami that swept away cars, homes and businesses as it touched land. The communication infrastructure was among the victims. Rapid rebuilding of the telecommunication system becomes an absolute priority.

GEOPHYSICS, SEISMIC, and ATMOSPHERICS RESEARCH RECEIVER
Type RAS-1
Called the RAS-1, the receiver is designed for ultra low and very low frequency scientific research work, including the exploration of low frequency emissions due to seismic and earth-quake activity, study of atmospheric phenomenon such as "whistlers", and low frequency Sudden Ionospheric Disturbance (SID) and electromagnetics phenomenon. The RAS-1 will receive signals from under 200 Hz. To over 250 KHz in both narrow bandwidth modes as well as broad badnwidth reception.

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.

Servo type Accelerometer
A motion is sensed by a displacement detector, a current is fed to the coil to get back the pendulum mass to the original position. This current will be proportional to the acceleration, that is converted to an output voltage. The Servo type accelerometer is for the Earthquake Monitoring or measurements of micro tremor on the Civil Engineering Structures because of its higher sensitivity and stability or more accurate phase responses in the lower frequency range than those of other vibration transducers.
