I have a PID controlled Gaggia Coffee that I've added pressure modulation with phase control to taken from the espresso for geeks project linked below except using an Arduino. Does anyone know of any food safe pressure transducers that could be used in an application like this?
He was using a transducer similar to the below. The body is 316 SS which is fine in food applications but I'm not sure on the internals that are touching the fluid stream. I could put a long capillary tube on it to limit the contact with the water for espresso but I would prefer to use known food safe materials. I believe the Decent machine has a pressure transducer so these must be on the market, I'm just not certain where they are.

Thanks, I'll keep an eye out for one if a more cost effective option doesn't pop up.
