Hi Everyone,
I thought I start this topic, to gather as much information as we can, in the hope for an ultimate recipe, to eliminate the vibration of the needle.
I'm far from expert in this topic, so every input would be greatly appreciated.
I'm aiming to start the experiment next week, where I'm willing to test the the following variables on a freshly rebuild machine with a stainless steel 41.3mm (1 5/16") glycerine filled gauge:
- Water filled / air filled capillary tube
- Length of capillary tube (short straight / short single coil / longer 5-10 coils)
I would appreciate some input on theoretically ideal length, if such exists.
- Height of gauge in reference of sampling point.
- Sampling point: boiler in-feed / outfeed
Sorry I'm not planning to test the pump outfeed (T piece on PTFE tube), as I can't see it any chance for it being any better by going closer to the vibratory pump.
- Routing
I would also appreciate some input on this.
I'm open to test other reasonable variables too, feel free to give suggestions
For your reference, I attach photos of my actual kit.
Also link a couple of videos I made last year
Bad one:

Good one (I suppose):

Thank you in advance for all your support and expertise.
