Watts 082 is a 10 kΩ temperature sensor designed to be strapped onto a pipe, and which can be used with select Watts Radiant control sensor inputs. It is most commonly used to monitor supply and return water temperatures. It has a brass sleeve for fast response, a wide operating range, an indent to allow pipe strap-on installation, and 8 ft (2.4 m) of 2-conductor wire.
