A Suggestion
PDTC: Pressure Detector-Creates a spark when pressure changes.(Not a good description but i cant really think of a better one.)
Does not conduct heat, Indestructible.
You can set the temp of the PDTC to change which pressure it detects.(like how PUMP and GPMP works.)
Use tmp to change if it sparks above that pressure or below the pressure.(tmp=0:sparks when pressure is above its temperature,tmp=1:sparks when pressure is below its temperature.)
Does not create a spark when pressure is equal.
It would work well when used with PUMP.
I have tried something like that but the best pressure detector i could make was DTEC(PSTS) and PSTE, but it wouldn't work with negative pressure and isn't as customisable as my suggestion.
Sounds good.
Pressure sensor would be cool. However, for now you can use vaporization temperature of DSTW to detect negative pressure. It works quite well. I used it on an EXOT/ISOZ Reactor I made a few weeks ago to detect if the reactor housing is near 0 or near -30. The lower your pressure is, the lower the temperature required to change DSTW to WTRV. I think it works in reverse too. but not too sure, haven't tried it.
You may be happy to hear I already have code for this...
