LTME is a high-end capacitive MEMS accelerometer which is specially designed for strong motion class B seismic measurements. Thanks to its extremely low noise, low power and wide frequency response the LTME family guarantees accurate and stable seismic measurements without the need for recalibration or maintenance during the lifecycle of the system.
LTME is available in three dynamic ranges 90, 100 and 110dB and different full-scale ranges depending on the model (±2g, ±3g, ±5g).
The broadband linear response is from DC to some hundreds of Hz (different for each version).
LTME sensitive elements are mounted orthogonally and housed in hard coating aluminum case IP67; IP68 is available optionally.
The resolution of the entry level model 90dB, meets all the requirements for strong motion event monitoring. Already in presence of light tremors, the data output is completely overlappable with mechanical force balance. The LTME response fades into noise when the ambient noise is low, whereas a true force balance can provide consistent information.
The graph below is a comparison between one of the most popular true force balance mechanical accelerometer for seismology and LTME.
