Good PR: PCB's sensors are advancing dummy data acquisition and test vehicle instrumentation

摘要

Piezoresistive crash accelerometers are used exclusively in automotive ATD applications as opposed to AC coupled accelerometers. Piezoresistive accelerometers have the capability to measure DC or steady-state accelerations and allow acceleration data to be easily integrated to provide velocity information during crash events. Vehicle safety tests may be performed at a component level with only a portion of the AID used or as a complete system. Tests may involve a sled, pendulum, or drop test apparatus requiring a specific transducer mix for each test setup. Testing may be generated for R&D, certification requirements, or calibration purposes. Various test standards recommend transducers for use in instrumenting ATDs with performance characteristics and physical dimensions identified.
