Hi
I'm doing a project to automate my heating with MAX gear and FHEM (some details on my blog at gw0udm.wordpress.com if anyone is interested). I've got a combi-based system and I'd like to find a way of monitoring the pressure in the system and logging it, also so that I can get advance warning if the pressure is dropping.
I've found a few transducers on ebay which are presumably more designed for cars but I don't see why I couldn't use one -eg:
http://www.ebay.co.uk/itm/0-5-4-5-V...470230?hash=item236328bf96:g:uqgAAOSwFNZWxZe-
All the ones I can find seem to use quite a small thread, but I can't seem to find anything which I could use to connect this in to the main heating system (mostly 15mm pipes). Have I missed something? Has anyone else tried to do thos?
I'll need to get a plumber to do this for me anyway but would like to make sure I can get all the bits first.
I'd welcome any thouhgts
