RE: Measuring CH water temperature?

["Neil Ball" <neilball@xxxxxxxxxxxxxxx>]

I would recommend you look for immersion sensors of a type/range
suitable
for you needs that can then be installed in matching sensor pockets that
are
plumbed into your pipework. The pocket usually comes in brass or stainless
steel and means the sensor element is not exposed to the water which would
damage it eventually. It also means the sensor is easily replaceable
without
draining down or compromising any water tight seals. It's what would be
used
in a commercial environment by a BMS/controls supplier. Sensors &
pockets of
various types should be available from Sontay or Titan, a quick Google
should take you to their websites.

Hi all,

For some reason, I now want to measure the temperature of my central
heating system. While I could tape a temperature sensor on the pipe,
I think the reading would be inaccurate and unreliable, I would like
to be able to immerse the sensor in the water itself. I'm going to do
a lot of plumbing with my central heating system soon, so I'd like to
plumb in the sensors while the system's drained and pipes cut/
disconnected, and connect the sensors up later on. Do anyone know of
something like a short pipe and a temperature sensor embedded in the
pipe ready for plumbing directly into a copper/plastic central heating
system? If not, can I put something similar together without
compromising the pressurised system? I don't fancy leaks like
everyone else :)

Thanks for your help in advance!

Regards - Piers
