Model based calibration of accelerometers

A novel procedure for the calibration of accelerometers is transferred to industry. The procedure, developed recently at PTB particularly for the field of high intensity shock calibration, allows in contrast to present calibration methods the determination of the input/output behaviour of a transducer also for transient. The novel method is based on an analysis of a second-order dynamic model for the input/output behaviour of the accelerometer. The project is carried out jointly with SPEKTRA Schwingungstechnik und Akustik GmbH Dresden. SPEKTRA provides calibration systems and is accredited for the calibration of accelerometers.
