These piezoresistive accelerometers are based proven MEMS technology, in which four variable resistors are configured as a Wheatstone bridge. In the ASC Crash Sensor series the uniaxial ASC 66C2 features the widest dynamic range from 0 Hz to 4 kHz and the highest impact resistance up to 10,000 g. In addition, the lightweight design allows its use in applications where the mass load of the test structures has to be minimized.
The accelerometers feature a lightweight, reliable aluminum housing with protection class IP65 and an integrated cable with configurable length and connectors.
Piezoresistive accelerometers are used in high-impact and shock applications such as side and frontal impact tests in the automotive sector. With a measuring range of up to 6,000 g they therefore belong to the category of ASC crash sensors, which can be configured with TEDS and EQX data.
