Thermocouple wire, is used to connect to the control room of the cold junction of the thermocouple display instrument, the cold end temperature compensation. And because the thermocouple variety, different types of thermocouple to be equipped with corresponding thermocouple wire. But when in use, for a variety of thermocouple wire is comprehensive use, many people can't tell.
the following project will tell you J type, T, K type thermocouple line how to distinguish.
a: look at the color of the insulating layer:
by insulating layer to determine the dividing thermocouple wire color number, but this method only the thermocouple wire, if the thermocouple compensating conductor shall not apply.
a red and a yellow number K type dividing
a red and a white number J type dividing
a red and a blue number T index
2: see the thermocouple wire - Wire
J type dividing thermocouple wire, one of the root material is iron, can use a magnet to absorb;
J type dividing thermocouple wire, one of the root material is copper, we can see the obvious yellow wire
the above two methods is experience, not necessarily is suitable for any occasion, if need to be very accurate thermocouple wire dividing, can try to measure the electromotive force.
more high quality thermocouple sensor
key words: thermal resistance, thermocouple, thermal resistance, platinum resistance, PT100, PT1000, pressure thermocouple sensor, digital temperature thermocouple sensor
