<p>PROBLEM TO BE SOLVED: To solve problems concerning measuring in a nozzle part, and more precisely grasp temperature fluctuation of molten resin by constituting so as to measure temperature outside of a nozzle part, and measure in the center of flowing molten resin. SOLUTION: An introducing opening 2 of molten resin butted into a nozzle tip 11, and a molten resin passageway 4 communicating with the introducing opening 2 are bored to a body 1. A temperature sensor 6 is installed on the longitudinal axis of the introducing opening 2. Through the butting of the introducing opening 2 into the nozzle tip 11, a temperature sensor terminal of the temperature sensor 6 is positioned opposite to the flowing direction of molten resin, thereby the temperature of molten resin flowing from a nozzle 10 can be measured. And a pressure sensor 13 is installed from the upper part of the body 1 toward the molten resin passageway 4 near the temperature sensor 6.</p> |
