Abstract
A hose for carrying liquid, such as hot melt adhesive, within a predetermined elevated temperature range. The hose includes a tube or body portion which has an inlet end adapted to connect to a source of liquid, such as a supply tank, and a discharge end adapted to a connect to a liquid dispensing apparatus, such as an adhesive dispensing gun. At least two temperature sensing devices, each having an output end, are also operatively associated with the tube to sense the temperature of the liquid therein. An adapter has a first end selectively connected to the output end of the first temperature sensing device. The adapter also has a second end adapted to connect to a controller which is compatible with the first temperature sensing device and not the second temperature sensing device. With the first temperature sensing device connected to the adapter, it is operative to sense the temperature of the liquid in the tube. In contrast, because the second temperature sensing device is not connected to the adapter, it is inactive and provides no temperature information concerning the liquid in the tube. The hose further includes a second adapter which is capable of replacing the first adap…
