["Pulse" piezoceramic transducer]

A piezoceramic acceleration sensor "Pulse", devised by the Gorky Scientific-Research Radiphysical Institute is described. The use in the sensor's design of a flexing sensitive element provides for high sensitivity and great power output of the instrument. This helps to easily coordinate the operation of the sensor with that of the recording devices and to record both the low-frequency curves, viz. ballisto-, kineto-, seismocardiograms, tremorograms and the high-frequency ones, such as phonocardiograms, Korotkov's sounds, laryngograms.
