Thermal accelerometer filled with gas inside the sensor instead of moving mass , so that don’t have stick & drop test issues.
The gas inside the thermal accelerometer is a natural low-pass filter, it is not sensitive to the high-frequency vibration(eg:motor's vibration ).
This is mainly because our thermocouple has a long (millimeter) distribution of cold and hot poles,the offset of our X/Y axis does not change much before and after SMT.
The zero-g offset is very low via our factory trim.It has a high tolerance for stress and will not change greatly due to the stress produced by SMT.
