납땜 철 온도계 고온 온도 온도 와이어

온도 감지 와이어 is an 중요 작은 부품 의 전기 납땜 철 온도계. The 온도 is 0-600 degree . It can resist corrosion and oxidation and is easy to replace. The electric soldering iron tests the temperature by touching the temperature-sensing wire.
열전대 are commonly known as "thermocouples" and there are many types.

작동 원리 of the 온도 감지 line:
There are 3 terminals on the temperature sensing line, 2 of which are divided into positive and negative, and the third is for automatic compensation. In terms of the design of the temperature sensing line, some are two-wire system and some are three-wire system. Short-circuit the " plus /-" of the temperature-sensing line with the third line respectively, and end with the output temperature being normal. But the basic principle is to use the corresponding relationship between a certain material and the temperature change, and form a closed loop through two material conductors with different components. When there is a temperature gradient at both ends, there will be current passing through the loop. There is an electromotive force - thermal electromotive force, which is the so-called "Seebeck effect". After the potential signal is amplified by the amplifier circuit, it is converted into an AD signal and displayed with an LED or pointer.

언제 테스트 납땜 철 팁, 지불 주의 to:
1. Before testing the temperature of the electric soldering iron, the electric soldering iron must be heated to a temperature that can melt the tin wire normal before testing;

2. Keep the electric soldering iron and temperature sensing line clean, remove the tin remaining on it, put the electric soldering iron close to the test area, and then add a little tin bead on the tip of the soldering iron;

3. Put the electric soldering iron in the middle of the temperature-sensing line, 30 degrees with the temperature-sensing line, keep it for about 4-5 seconds, and the temperature of the soldering iron head will be displayed.
