This K-type thermocouple temperature sensing wire is a common thermocouple wire and thermocouple standard wiring, which can be used for K-type imported and domestic temperature recording instruments.
The difference between precision wire and ordinary wire: the density of ordinary wire is lower than that of precision wire, and the gap is larger, which seems to be similar. Because the principle of thermocouple is that the thermoelectric electromotive force generated by two different materials of metal is only a few millivolts, so a little interference will reduce the measurement accuracy. Of course, users with low requirements can choose ordinary wire. The shunting effect of thermocouple wires in high temperature environment is caused by the reduction of insulation resistance of insulating materials due to temperature rise,
The precision line is insulated by double-layer high-temperature refractory glass fiber (ordinary single-layer), which effectively reduces the shunt effect and ensures the accuracy of long-distance measurement!
