New type description [Technical field to which the new type belongs] This creation is about a temperature sensor, and especially about a thermistor temperature sensor. [Previous technology] Thermistor temperature sensor is a type of temperature sensor that uses a thermistor as a temperature sensing element. It is often used in air-conditioning systems, cold beam refrigeration equipment, and # heat treatment equipment. However, the conventional thermistor temperature sensor is connected to the thermistor temperature measuring element sealed in a metal or plastic container with a group of wires. However, this thermistor temperature sensor can only measure the temperature of a single reference point, and responds slowly to changes in the temperature of a wide range of targets, and because of the temperature of the conventional thermistor temperature sensor Conduction must be performed on the surface of the metal or plastic container and the internal package. The measured temperature and the actual temperature often have considerable errors. In addition, the conventional offering — Jain ’s thermistor temperature sensor cannot measure the strict surface production of other parts with the shape of the target object. Therefore, it is necessary to provide a fast response, reduce the measurement surface borrow + denwa A comprehensive contact thermistor temperature sensor with large column area and accurate measurement.
