A thermocouple is just two wires of different metals, joined at one end. If you know the wire materials for the type thermocouple you want, you can weld the tips together so the cost is in the wire. Fancier store-bought thermocouples can have color-coded wire, insulated junctions and other features that add to the price.
Thermocouple wires typically contain a small percentage of platinum, usually less than 10%. The exact amount of platinum in a thermocouple wire will vary depending on the specific type and manufacturer of the wire.

Is platinum wire a element?
Platinum is a chemical element.
Why is platinum used to make wire?
Platinum is used to make wire because it has high electrical conductivity, is resistant to corrosion, and has a high melting point. These properties make platinum ideal for applications that require durable and reliable wire, such as in the electronics and aerospace industries.
Why is it necessary to clean the platinum wire between flame tests?
because platinum wire loops dont impart any color of it own.... NICHROME wire are also used..
What is platinum thermometer?
A platinum thermometer is a type of resistance thermometer that uses a platinum element as the temperature-sensing material. Platinum is often chosen for its high accuracy and stability over a wide range of temperatures, making platinum thermometers suitable for precision temperature measurement applications.
What is the evidence that indicates that only physical changes occur when a platinum wire is heated in a Bunsen burner flame?
The evidence that indicates only physical changes occur when a platinum wire is heated in a Bunsen burner flame includes the fact that the platinum wire does not combine with oxygen or any other element in the flame to form a new substance, and the wire retains its chemical properties after cooling down. The color change of the wire due to heating is a reversible physical change, and the wire can be restored to its original state without any alteration in its composition.
Which materials could you use to create a thermocouple?
To create a thermocouple one needs thermocouple wire, a means of spot welding the wire, and wire strippers. A thermocouple is used to measure temperature.
What is maximum voltage produced in thermocouple?
A:The best platinum thermocouple can give upto 64mv
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.
How do you splice thermocouple wire?
One splice that would work is a western splice.
What is the maximum power in Watts that can be attained from a thermocouple?
not much, but it will depend on the type of thermocouple
What is the best wire that is used in rings?
If your ring is gold and you gold wire and if your ring is platinum ring then using platinum wire...
Is platinum wire a element?
Platinum is a chemical element.
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.
Why is platinum used to make wire?
Platinum is used to make wire because it has high electrical conductivity, is resistant to corrosion, and has a high melting point. These properties make platinum ideal for applications that require durable and reliable wire, such as in the electronics and aerospace industries.
Why is it heating a platinum wire in air is a physical change?
Heating a platinum wire in air is a physical change because it does not change the chemical composition of the platinum wire. The heat causes the platinum wire to expand and may change its physical appearance, but it remains chemically the same.
Do automotive sensors have platinum?
The MAF sensor has a tiny platinum wire in it.
Why is it necessary to clean the platinum wire between flame tests?
because platinum wire loops dont impart any color of it own.... NICHROME wire are also used..
