FAQ
1. Q: Why go for piezoresistive (instead of capacitive) MEMS in this sensor?
A: By employing the piezoresistive technique, the sensor can output a true DC response (0 Hz), which is indispensable in capturing the whole low-frequency content of long-duration shock pulses, as in crash testing and blast monitoring.
2. Q: What installations happen to call for a 70,000g survival rating?
A: The reason why this very high rating must be permitted is that the forces which occur during ballistic impacts, pyrotechnic events, and explosive blast monitoring far exceed the sensor’s measurement range. The rating, therefore, enables the sensor to survive and the data to remain accurate.
3. Q: The sensor possesses a considerable zero offset (2.5V). What is the impact of this on signal acquisition?
A: Because of the big offset, your data acquisition system will have to have either AC coupling or a bipolar power supply. It is indeed a must if signal clipping is to be avoided and positive and negative shock pulses are to be correctly recorded.
4. Q: What is the reason behind the ±20,000g to ±50,000g range?
A: Occasionally, the sensor is taken to the limits of its range when there is an extreme transient event like projectile impact, armor testing, or an airbag detonation, when accelerations are likely to really go beyond the capability of a conventional industrial sensor. That is where these ultra-high ranges come in.
5. Q: Apart from the usual, how should this sensor be installed?
A: The sensor is capable of responding to frequencies as high as 20 kHz, so it must be firmly fixed with the M3 screws provided to a clean and flat surface. Because the case is conductive, a single-point ground connection must be used to reduce electromagnetic interference in a noisy testing environment.
