- The Magnetostrictive Dynamic Strain Sensor is a permanent-magnet constant-flux excitation sensor and thus requires no other electrical excitation or power source. It does not require any signal conditioning. Since it is a constant-flux dynamic sensor, it does not generate any offset voltage and it does not exhibit temperature or drift problems. Furthermore, the sensor is rugged, simple and inexpensive.The sensor's time-averaged output is constantly zero. The sensor detects only dynamic events such as impact, crash, firing (or misfiring) of an engine cylinder, piston slap, vibrations of a machine component, vehicles passing through a bridge, etc. Therefore, the sensor has many promising automotive applications including crash and misfire detection.
