Do you need to use TC extension wire to connect a thermocouple or can you use shielded cable?
You must use thermocouple wire (of the same type as the thermocouple) to extend the circuit. If you switch to a different wire the point of connection between the two becomes a thermocouple junction itself, and the resulting voltage from that junction will skew your reading. You can use any wire to extend a thermocouple connection if you know the temperature of the junction where the thermocouple wire ends--this becomes the reference junction.
Can copper wire be used for thermocouple extention?
No. A thermocouple is made from two dissimilar wires. At the junction of these two wires, an electrical signal is generated that is measured in millivolts. If you insert another type of wire, such as copper, then you have introduced another electrical junction. Your signal will be (millivolt from junction 1 + millivolt from junction 2). <><><> Maybe. A thermocouple measures the temperature difference between the sensing junction (where the two different metal wires meet) and the other end of the wire, the reference junction. If you extend a thermocouple with copper wire, you will measure the temperature difference between the junction and the location where the copper extension is spliced on. If the copper splice is the same temperature as the reference junction, or if you can measure the temperature at the splice, then it will be fine. In general, it is better to run the thermocouple wire to the reference junction.
What is the function of thermocouple?
The thermocouple does not actually measure temperature, but the temperature difference between two points. If the temperature at one point is known (reference junction) then the temperature of the other point (sensing junction) can be calculated.
Thermocouple instruments are also known as?
The thermocouple is a sensore used to measure temperature. The thermocouple are made with two wires of different metals. joined together at one end to from a junction the thermocouple outputs in a a Milli volts .

Does a thermocouple have to touch at the tip or sides to operate correctly?
All thermocouples (whether type J, type K, type T, etc.) measure the difference in temperature between the Tip (junction between two different metals), and the other end of the thermocouple wire, often referred to as the "cold junction." There must be two such junctions somewhere for the thermocouple to operate correctly; typically the measurement junction is at the tip. To measure the temperature of some thing, try to put that junction as close as possible to that thing. However, since the thermocouple is metallic and the measurement relies on detecting tiny voltages, connecting the tip electrically to a metallic surface could affect the measurement. For that reason thermocouples often have insulated tips.
What is a thermocouple thermometer?
Thermocouple is made up with the junction of two different metals(e.g. antimony and bismuth). This is the device used to measure the temperature due to the fact that when two junctions are placed at different temperature a potential difference developed (thus electrical signal) which is proportional to the difference in the temperature of the two junction. This is very sensitive device.
How does a thermocouple work on a gas boiler?
A Thermocouple is simply a temperature-sensor consisting of a junction between two metals, where the tiny voltage between them varies with temperature. This change in voltage can be detected and acted upon by the electronics controlling such things as boilers.
Working of thermocouple?
A device for accurate measurement of temperature difference between two junctions. A thermocouple consists of two dissimilar metals joined at two joints in a loop so that the difference in voltage can be measured. If the temperature of one junction is known, the other junction temperature can be calculated. Since voltage changes in proportion to temperature, the voltage difference indicates temperature differences.
What does thermocouple means?
sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured.
How do you convert output voltage of thermocouple into temperature?
You need to know the temperature of the reference junction and the voltage difference between the reference and sensing junctions. First, you convert the reference temperature to a voltage using the reverse equation or table for your thermocouple type. Then you sum that voltage with the measured voltage. Finally, you convert the summed voltage back to a temperature using the equation or table for the thermocouple type you are using. If the reference junction is at zero degrees C, you can skip the reference summing part. Before computer processing was easy and cheap, the reference junction was often kept in an ice water bath for that reason.
What must happen to the voltage and resistance for the circuit to get cold?
For the circuit to get cold it must include a reversed junction thermocouple like in an electrical thermocooler.
