wow high tech ar...
but sorry to ask there is a 0.05bar dead band pressurestat.
electronic one more durable and better ?
Thanks for teaching.
0.05 bar pressurestat data sheet:
http://www.barksdale.com/download/?dl=505
mine is 0.2-0.3bar , due to the durable issue, I have given up the upgrade.

用壓力控制，保證打奶壓力
其實PID 去控制水溫，反應會快d
用壓力PID去控制會有delay

現時個控制是0.80bar,加熱去到0.88bar
水溫98~99
仲試緊setting

改左，我吾使較PStat去改壓力
if you own a dual boiler machine, dont waste money to do upgrade like this.
It wont give you too much different.

Someone come with a "home made" pressure profile upgrade, which is great.

Ps .請大家吾咁輕易去改expo bar ,基本每一樣都要定做

Do you keep the original PSTAT (set to just higher than the PID pressure) in serial with the PID control (SSR) ? In case of the PID fail (always on), the PSTAT could be the final protection.

It has a safety valve @ 2 bar something
I tested, no problem.
I foundD out inside no space to keep the original pstat.
Also You have to refit the copper tube.

Alexfan I like you pressure profile upgrade. Is it good?
