TDC1000-C2000EVM: TDC1000

Part Number: TDC1000-C2000EVM
Other Parts Discussed in Thread: TDC1000, , TUSS4470, BOOSTXL-TUSS4470, PGA460PSM-EVM

 

Gentlemen:

We intend to make water level measurements in low level water tanks (around 10 cm depth, with variations around 5 mm). The application will be in field situations (outer environment).

Your technical notes about the TDC1000 Ultrasonic AFE indicate a solution that seems adequate for our purposes, with depth resolution better than 1 mm for a 1MHz transducer.

Your notes and user guides consider two boards:

TDC1000-TDC7200EVM

TDC1000-C2000EVM

Because we have a very small volume for housing the electronics, could you please inform us the dimensions of the two boards (Length, width, and approximate maximum thickness with the onboard components)? It would be of great help for us. Because of the indication of two boards, could you please also inform what would be the best for our low level water measurements?

Thank you in advance for your answer.

    Hi Harry,

    The TDC1000-7200EVM has been obsoleted, so you're only option to evaluate the TDC1000 device is to use the TDC1000-C2000EVM.

    The dimensions of the TDC1000-C2000EVM are as follows: 13.2cm x 8.6cm x 1.5cm (L x W x H). You can find the 3D STEP file of the TDC1000-C2000EVM here: https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/1023/TDC1000_2D00_C2000EVM_5F00_3DStep.step 

    An alternative to the TDC1000 device is to use the TUSS4470 at 1MHz. The BOOSTXL-TUSS4470 is the recommended evaluation tool for the TUSS4470.

    You can see the differences between these two devices on the Ultrasonic FAQ page here: https://e2e.ti.com/support/sensors/f/1023/t/748143

    Gentlemen:

    Thank you for your prompt answer. 
    The length of 132 mm of the described dimensions of "132 mm x 86 mm x 15 mm" (L x W x H)  of the TDC1000-C2000EVM board exceeds our available space.

    You also mentioned the alternative device TUSS4470 at 1MHz, with the BOOSTXL-TUSS4470 as evaluation tool for the TUSS4470.  

    Could you inform me the dimensions of the furnished boards? (It seems that now there are two boards, if I am not mistaken).

    Thank you in advance for your answer.

    Harry,

    For the TUSS4470, there are two boards to consider:

    1) BOOSTXL-TUSS4470: this is the full evaluation module available for purchase through the TI eStore. It's dimensions are 1.8" x 2.25" x 1" (L x W x H).

    2) TUSS4470PSM: this is a small form factor proximity sensor module reference design measuring 0.42" x 0.8" x 0.4" (L x W x H). This solution is not available for purchase, but can be fabricated and assembled with the linked project files from the product page: Direct-Drive Ultrasonic Proximity Sensing Module Design Files (TUSS4470PSM)

    If you cannot get boards built, and need a small off-the-shelf solution, the PGA460PSM-EVM is available, but only support transducers up to 480kHz. You would need to replace both the transformer and transducer on this EVM since it comes standard with a 40kHz transducer and transformer combination. A high frequency transducer, such as a 400kHz transducer, can detect up to 10cm no problem, but may be limited to a 1~3cm minimum.

    Gentlemen:

    Once more, thank you for your prompt answer.

    The dimensions of item 1 of your answer seem to be OK for our purposes. It remains only one doubt, related to the ultrasonic sensor.

    In the first message sent to T.I. I mentioned the TDC1000 configuration for water level measurements. Our intention was to use the transducer SMD15T21R111WL provided by STEMiNC, as suggested in the notes of T.I.

    The last question is: is it possible to use the transducer SMD15T21R111WL provided by STEMiNC together with the TUSS4470 configuration?

    Thank you in advance for your attention to this question.

    Hi Harry,

    Yes, it is possible to pair the TUSS4470 with the 1MHz Steminc SMD15T21R111WL  transducer.

    You can see example time-of-flight results of this combination in the Logarithmic Amplifier for Ultrasonic Sensor Signal Conditioning app report, section "4.2.3 Fixed Gain at High Frequency".
