ultrasonic transducer

i am using multisim 10. i want to simulate ust-40r (or 400st/r160) ultrasonic transducer. i cant find the spice models for it. please help

also suggest if there is any alternative that i can use for simulation purposes.

Hi, 

 

It is very unlikely that you will find a SPICE modle for  this component.  The only component that I can suggest you look at is the voltage control resistor  which can be found in the Basic Virtual family.  The input to the control resistor is voltage so you can use various voltage sources to control the resistance.

Hai,

Can I see your circuit please.
Just want to make a reference..

Thanks.

An ultrasonic transducer is probably a piezoelectric device. As such it will look like a capacitor possibly with a resistor to represent the power and a voltage or current source to represent the response to mechanical stress. Finding a suitable equivalent circuit and determining how to model it will likely require detailed information about the internal structure of the transducer and only be available from the manufacturer, if at all.
