Description

Thermocouple Temperature Wire Structure

This work is about temperature measurement, especially a thermocouple temperature line structure.

A thermocouple is a widely used temperature sensor. When the traditional thermocouple structure is applied to the temperature wire adapter of a multimeter, the temperature wire is mainly connected to the inside of a metal end formed by a hollow copper tube or copper column, and through the metal end and The measuring port hole in the meter jack is butted. Accordingly, the temperature effect voltage signal of the thermocouple temperature wire will be transmitted to the metal terminal, and then transmitted to the measuring rod in the socket of the electric meter through the metal terminal, thereby achieving the purpose of temperature measurement.

However, in the existing thermocouple structure, due to the different materials of the measuring probe and the metal tip, the joint is where the room temperature thermocouple of the socket is generated, and the thermocouple effect voltage generated between the two is not the real temperature. In addition, the temperature effect voltage of the measurement object of the measuring probe will transmit the temperature voltage through the metal end, due to the room temperature heat generated by the junction of the temperature wire of the measuring probe and the metal end The galvanic couple effect voltage cancels each other out, so the measured deduction temperature of the measuring terminal of the ammeter must be synchronously and stably deducted from the room temperature thermocouple effect voltage at the joint of the metal terminal, otherwise the measured target temperature will be caused by the inaccuracy of the ammeter. Simultaneously offset the room temperature at the junction of the metal terminals, but it does not match the actual temperature, which affects the accuracy and precision of the measurement results.

In view of this, the author of the present invention, aiming at the above-mentioned prior art, devoted himself to the research and cooperated with the application of theories, and tried his best to solve the above-mentioned problems, which became the goal of the author's improvement.

One of the purposes of this creation is to provide a thermocouple temperature wire structure, the insulating end of which is made of plastic material and is not easily affected by external temperature (such as room temperature), so that measuring instruments such as electric meters will not be affected by the temperature received by such as The temperature difference is caused by the influence of external temperature such as room temperature, so as to maintain the accuracy and precision of the measurement results.

In order to achieve the above purpose, the present invention is a thermocouple temperature line structure, which includes a base, an insulating terminal, and a temperature sensing group. The insulating terminal is fixed on the base, and the insulating terminal is provided with a positioning part. The temperature sensing group includes a temperature wire passing through the insulating end and an elastic wire extending from the temperature wire and protruding out of the positioning part.

Compared with the conventional one, the thermocouple temperature line structure of this creation can measure the temperature of the object through a thermocouple temperature probe and obtain a measurement signal, so as to transmit the measurement signal to measuring instruments such as electric meters . Since the insulating terminal is made of plastic material, it is not easily affected by external temperature and undergoes instantaneous changes. Therefore, there will be no temperature difference between the temperature probe and the temperature sensing group of this invention, so the accuracy and precision of the measurement results can be maintained. In addition, the insulating terminal is made of plastic material, which can simplify the manufacturing process and assembly, and can reduce the overall cost of the thermocouple temperature line structure, increasing the practicability of the invention.
