hi,
Attached the LTS 'asc' file, just click and run.

Hi eric,

can you share your LTspice library folder, it seems my library does not have few components of schematic and is giving error in simulation.

 

hi,
My Lib folder is over 30MegaBytes.!
Which components are you not seeing on the asc file.?

1. 2n7002
2. Lm393
3. CA3140

What is new in this circuit from previous circuit that you have posted.?

 

hi,
Unzip this file, place the files in your lib folder.

Still I am getting the same error, also the format of the files is different......

 

I have just download the zip and it works OK for me.??
What format is different.?

It is .mod file, I copy pasted the 3 files to lib folder and started the .asc file you sent, but still showing error that the components not found..!!..Is there any step that I am missing?..

 

hi,
Unzip this file it contains the 'asy' files

Where should I place the .mod file, the .asy files are working, but the .mod file is still not found by the simulator....

 

Put all those files in same folder as the TX1Mhzb.asc file

Yes, I placed the .mod file in the same folder as .asc file still getting this error :
Fatal Error: Could not open include file "LM393A.5_1_ti.mod"

 

hi,
Do you have a colleague who is familiar with LTSpice.?
It will be quicker to find the problem at your end.

No, no one is familiar with LTSpice. But I am finding, I got the issue..I am fixing it...
I am not able to edit the 2n7002 model, I have fixed the fatal error problem, but when i tried to edit the 2n7002 model, it say's component cannot be edited...!
Solved, I am able to simulate the results now..

 

Hi,
Thats good news.!
When you are ready post any asc files you would like me to check through with you.

Hi Eric,

Please find the attached .asc file. I am planning to build the TX something like that, but the output from echo side is kind of steady...

 

Missing 0V/Common connection between the circuits.




Added: set a 0.1m delay before plotting, to not show the TX period.

Can you edit it and send the .asc file, I am having trouble setting it up...I have to take a day or two to get familiarized with LTspice..

Hi EricGibbs,

Please check the following .asc file and provide your output on it.

Also, I guess the circuit that we designed is simulating well, but the only thing is the transducer could get an echo back from the container. Any idea is to what else can we do so that we could get echo back from inside the steel container.

 

hi,
I will at the simulation,
Why have you have changed the TX circuit back to the original design.? also you have two transducers across the pz to 0v output.
Both of the transducers are not a correct representation of a real transducer.
