Off the top of my head... considering both gauges are analog in nature and considering both would have had some form of factory calibration its understandable they may not have adhered to the same calibration standard. Also, its conceivable the older gauge you are using may have drifted or been knocked out of calibration over the years. If it was a huge concern and I was to suggest anything it would be to simply replace the pressure gauge with one that would allow for more granular readings... like 0-10 bar or better yet 0-5 bar (instead of your current 0-14 bar gauge).Amberale wrote:Hi folks.
I have a question for those who have plumbed their Bianca.
I have an in line adjustable pressure regulator which drops my pressure to 2 bar.
I have tested this at the connection that feeds the machine with a different gauge which also shows 2 bar.
However at rest my pressure gauge shows 3-4bar.
Everything works but I am curious about why.
Now I'm off to clean these filthy things.
I've included a shot of my gauge situation. As you can see both of my gauges are close to providing the same reading but I personally don't think you have an issue as long as you can use your regulator to dial down the pressure and the gauge on your Bianca registers your desired pressure setting. Just FYI: With my old Cimbali Jr as well as my Reneka Techno I was advised to set line pressure at 2 bar.
