I'm looking for a "tube" type sight glass capable of handling 600 psi (maybe up to 50 C). No problem finding the "disk" type, or flat glass with the rating, but I'd prefer a tube. Just the glass would do as we could make the end fittings. Have any of you guys come across any good suppliers? (Actually an R&D application rather than a model).
Thanks
At that pressure we would normally use a metal enclosure with a flat glass window.The window is the same length as a normal gauge glass would be.The common type used to be Klinger.I suppose a google will turn them up. Mark.
Here`s a link.
Thanks for the comment and link (I had already found them). I guess perhaps the design logic at higher pressures is that the "flat glass" is easier to fix securely; with a tube type there may be more risk of relative movement between the end fittings which could cause metal to glass contact, initiating surface defects, and BANG. I'll have a think about acrylic or polycarbonate. We'll have a safety screen as well.
