| MicroSMA is a MEMS (Micro Electro Mechanical System) accelerometer offering excellent noise performance, low cost, robustness, immunity to electromagnetic interference and small size. It is field configurable for one, two or three components, compatible with NetDAS and DAQ24USB and runs from USB power. MicroSMA implements a FBA (Force-Balance Accelerometer) on a silicon chip providing excellent linearity and a high degree of ruggedness. Since MEMS technology does not employ a magnetic coil there is negligible pickup of spurious RF signals. The unit is available both with and without an enclosure for external or internal mounting. |
