Read air tank pressure to dashboard?

[Trinitrotoluene]

Our team is using pneumatics this year, and we'd like to be able to view how much pressure is in our air tanks from the FRC Dashboard. We are using LabVIEW.

I have a complete pneumatic system hooked up. When running a self-test on the PCM, it registers that "Pressure is full" when the compressor is shut off, so it obviously knows what the pressure is. Is there any way I can get this value into the dashboard?

You need a separate pressure transducer in order to read pressure. The switch just measures whether a certain pressure is reached, not what the exact pressure is.

Thanks! So something like this?

Hi Wyatt,

The control system doesn't have a native way to read pressure, however we sell an analog pressure sensor that you can connect to one of your analog inputs. You can then calculate and display your system pressure on the dashboard.

Take a look at the REV Analog Pressure Sensor and let me know if you have any questions!

Edit: Looks like you found it!

Do you know how this would be programmed in LabVIEW?

It's an analog input. The voltage read by the analog input linearly corresponds to the pressure of the system.

Thanks for your help, guys!
