Our temperature probes use RTD (resistive thermal device) Pt100 sensors instead of K-type thermocouples (TC) as they offer greater accuracy over the brewing temperature range. RTDs also remain more accurate over time (less drift which means less re-calibration).
The diameter of the outer flange (the flat disc part) is 1.988" (50.5mm). The 1.5" TC flange works directly with 1" (25mm), 1.33" (33.7mm), or 1.5" (38mm) Tri-Clamp fittings. Tri-Clamp probes with 1.5" TC flange can be used in 2" Tri-Clamp fittings (or vice versa) with a suitable adapter/reducer (not included).
Note: The flange size refers to the outside diameter of the tubing that it makes a connection for, not the flange diameter.
Are temperature probe tips interchangeable?
Yes. Any of our temperature probe tips can be used with any of our temperature probe cables.
