High Voltage Ultrasonic Pulser

We would like to show you a description here but the site won t allow us.

High voltage ultrasonic pulser.

Hv7360 is a high voltage high speed pulse generator with built in fast return to zero damping fets. The 5058pr high voltage ultrasonic pulser receiver is designed especially for test and measurement applications in sound attenuating mediums. It is designed for portable medical ultrasound applications. The design of the pulser is complicated by the high electrical impedance of the ultrasonic transducer high voltage is needed to supply the sufficient power.

For the generation of ultrasonic signals piezoelectric transducers are employed. Hv748 is a four channel monolithic high voltage high speed pulse generator. The major building block of the ultrasonic testing technique is a high voltage hv pulse generator also known as a pulser which energizes the piezoelectric transducer in the form of a high voltage narrow pulse width electrical signal. The compact pulser transmits a high voltage pulse with a user specified pulse voltage and width when triggered by an external trigger signal or by the internal prf timer.

The high voltage pulser generates high voltage pulses to excite an ultrasonic transducer through discharge capacitor. The maximum working voltage of ultrasonic transducer according to 9 is a function of the piezoelectric transducer s thickness. This high voltage and high speed integrated circuit is designed for portable medical ultrasound image devices but can also can be used for ndt and test equipment applications. 2 kv per mm of thickness.

This high voltage and high speed integrated circuit can also be used for piezoelectric capacitive or mems sensing in ultrasonic nondestructive detection and sonar ranger applications. Four preset programs are available to test the pulser in typical conditions and output waveforms can be displayed on an oscilloscope by. The steval ime014v1b evaluation kit based on the sthv1600 16 channel high voltage pulser for ultrasound imaging applications can be used to evaluate the characteristics and functionality of the hv pulser.
