Legality of using a pressure sensor on the high pressure circuit?

[dtengineering]

Wow! You're right... R82 does exclude pressure transducers from the high pressure side of the robot. You're also right that the high pressure side is the place where it makes the most sense to place them!

I know we've used transducers on the the high pressure side in the past... I'll echo the suggestion to submit a Q&A... it seems silly to outlaw a useful instrument such as this.

Good catch... even if the rule doesn't say what I, personally, think it should say!

In some earlier games, this was permitted. (See the diagram on page 26 of the 2005 robot rules.)

I completely agree that transducers should be allowed on the high-pressure side. In fact, I'd go further and say they should be allowed in place of the Nason switch.

There's no huge difference between reading a digital input for the Nason switch, and reading an analogue one for a conventional pressure transducer. The internal mechanical logic of the Nason can be accurately represented with a transducer and a snippet of built-in code.

Not so easy to bypass a pressure transducer to test and set the pressure relief valve. I'd keep the simple pressure switch.

Cheaper too.

Complicates inspection, so I'd vote no.
