TDC1000-TDC7200EVM: Delopment guidance

Part Number: TDC1000-TDC7200EVM

Hi 

So I am trying to test the TDC1000-TDC7200 EVM. I have the 1 MHz sensor that comes with it. 

EXP set up. 

I have a plastic and a glass container. I am just attaching the transducer using a cellotape for now. I see the following issues:

- Tank level stays at either 2.74 cm or when I reset the TDC1000 at 2.18cm

- The TOF flight reading generally do not correlate with water level. e.g. when I have no water tank on the sensor, it still gives a reading of about 37224 ns. 

- When I put a water tank with ~4 cm water, the reading is 37233 ns

Can you suggest what I am doing wrong?

thanks and regards

    Hi Akeem

  • Hi Sanjay,

    Thanks for your patience, we have seen that the transducers do not work well if not secured properly in the containers. Please attach the transducer as in the document in the link : www.ti.com/.../snaa266a.pdf
    & try your experiment with the TDC1000-TDC7200EVM, follow the GUI instructions as the User's guide you should be able to measure the tank level.
