We use a lot of electronic products in our life. It can be said that we can't live without electronic products. As we all know, there are all kinds of resistance wires in our electronic products. These resistance wires can ensure our safety when using electronic products. Compensation wire alloy wire should be familiar to everyone. It exists in almost all electronic products. In order to ensure the safe use of electronic products, the safe use of resistance wire is also very important. Let's have a look.
1. The alloy wire of compensation wire must be correctly selected according to the type of thermocouple used and the occasion used; 2. It shall be as close as possible to the two contacts of thermocouple terminal, and the temperature of the two contacts shall be consistent as far as possible; 3. The temperature at the connection with the instrument terminal shall be the same as possible. Where there is a fan in the instrument cabinet, the contact shall be protected to prevent the fan from blowing directly to the contact; 4. Generally, it is better to control the length of thermocouple compensation wire and alloy wire within 15m. If it exceeds 15m, it is recommended to use temperature transmitter to transmit signal; 4. The alloy wire of compensation conductor must be far away from the power line and interference source; Where crossing cannot be avoided, cross mode shall be adopted as far as possible, and parallel mode shall not be adopted; 5. In order to improve the anti-interference of thermocouple connecting wire, shielded compensation wire can be used.
