Depending how close the stirrer comes to the side of the bowl, I would cons= ider clipping a thermocouple probe to the top edge and having it run down t= he inside of the bowl. I'm thinking in terms of a stainless encased probe h= ere, and gently bending it to the profile of the side of the bowl, so it sh= ouldn't be more than about 2.5mm high above the bowl lining. For contents at around 200C you will almost certainly need a thermocouple a= s I don't think PRT probes for that temperature are too readily available (= you are getting into soldered termination melting realms, so unless the lea= ds are welded they will cause problems). -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of= Brent Brown Sent: 27 March 2018 11:43 To: Microcontroller discussion list - Public.
