Epson Electronics America Launches High-Performance Quartz MEMS Inclinometers & Accelerometers for Seismic, Industrial and Modal Analysis Applications New devices boast the compactness and energy efficiency of MEMS sensors with the high performance of The Wilcoxon Research Model 731A, an ultra high-sensitivity industrial seismic accelerometer designed for measuring both seismic and ultra low-level, low-frequency vibration on structures and objects, is now available from Meggitt Sensing Systems. Metrix seismic accelerometer sensors are capable of sensing a wide range of vibration frequencies, this seismic accelerometer sensor is ideal for use on a variety of machines. A built-in amplifier provides a high level, low impedance output for connection They tested the LIS331DLH MEMS accelerometer in an iPhone and compared it to the earthquake sensor EpiSensor ES-T force Berkeley Their hope is to create an urban seismic network that could transmit real-time ground motion data to a central location. High Wycombe, United Kingdom - 24th May 2007 - Monitran, a world leader in the design and manufacture of vibration sensors, has launched a high-sensitivity, low-frequency seismic accelerometer. The MTN/1450 serves three key markets: geological surveying Meggitt Sensing Systems has released a highly-flexible seismic industrial accelerometer known as the Wilcoxon Research Model 731A for monitoring the low-level as well as the seismic and low range vibrations occurring on the objects and structures. .

They hope that the sensitivity will improve as cell phone accelerometers get better. There are some obvious issues that would get in the way of using such a phone-based seismic network, however. For one, isolating the shaking due to the earthquake from In the 1990s MEMS accelerometers revolutionized the automotive airbag The current state of the MEMS sensors, suggest the authors, could be used for the creation of an urban seismic network that could transmit in real-time ground motion data to a Trimble has introduced an integrated GNSS reference receiver, broadband seismic recorder and a force-balance triaxial accelerometer for infrastructure and precise scientific applications. The Trimble SG160-09 SeismoGeodetic system provides real-time Traditional accelerometers use a “seismic mass” attached to a spring encased in some sort of housing. As the device moves the mass moves on the spring and the device can measure the movement. Using multiple units a device can determine which way the it .
