Abstract
A temperature sensor has a sensor tip and a front for measuring the temperature of the inner walls of tools, particularly inner walls of injection molding tools. The tip of the temperature sensor has two thermocouple wires of a thermocouple. Each thermocouple wire of the thermocouple guided to the front is welded to the sensor tip up to a depth which is larger than the total processing depth behind the front. The sensor tip is processable by removing of material at the front up to that processing depth.
Claims14
A temperature sensor having a sensor tip and a front surface for measuring temperatures of tool inner walls, and two thermocouple wires of a thermocouple wherein each of the thermocouple wires is guided in a respective bore defined in the sensor and at least one of the thermocouple wires is guided in its respective bore through the sensor tip up to the front surface, wherein each thermocouple wire guided to the front surface is welded to the sensor tip in a welding area up to a depth which is larger than a given minimum processing depth behind the front surface.
