Hello list.

I'm a long time lurker (~18 years?), usually have nothing to add above the
excellent content here.

I need to monitor the temperature of the liquid in a cooking vessel which
contains a rotating paddle/scraper that precludes me from simply inserting
a fixed probe. My first thought is to have a battery powered temperature
transmitter attached to the paddle - this would also provide a reading that
is averaged through the entire bowl as it moves through potential hot/cold
spots in the liquid. The sensor/probe itself could be mounted on the paddle
such that it is submersed in the liquid while the electronics could be
strapped to the paddle shaft that remains above the fill line, with a short
heat-proof cable in between. There will be steam and heat and oil splutter
there but I'm sure some protective measure could be employed to house the
electronics. The height of the liquid may be up to around 40cm, and get up
to 200degC.

A receiver could then display this temperature and eventually use it as
part of a control process.

Has anyone done something like this? Or any advice to offer? An off-shelf
solution would be preferred but I'm not finding much. (Lots of wireless
sensors but either for ambient temps, or without rugged transmitters). I'm
thinking maybe build a small battery powered board with a 433MHz tx module
and a suitable receiver but am hoping for something perhaps quicker to get
up and running.

TIA.

Kris.
