Thermocouple Wire
A Thermocouple is a temperature measuring device consisting of two conductors of dissimilar metals or alloys that are connected only at the ends. When the ends are at different temperatures a small voltage is produced in the wire that can be related directly to the temperature difference between the ends. If the temperature at one end is known, the temperature at the other end can be determined.
Application:
Thermocouple wire or extension grade wire is recommended to be used to connect thermocouples to the sensing or control instrumentation. The conditions of measurement determine the type of thermocouple wire and insulation to be used. Temperature range, environment, insulation requirements, response, and service life should be considered.
What do we have?
Thermocouple wire ( extension/compensation/compensating):
Type: K, T, N, E, J, L, B, R, S
Insulation or jacket: PVC, Telflon, PFA; Silicon rubber, Fiberglass, Quartz Fibre.
Sheild: Tin-coated copper braid/Stainless steel braid sheild.
Calibration Type Characteristics
Type J (Iron vs Constantan) is used in vacuum, oxidizing, inert or reducing atmospheres. Iron element oxidizes rapidly at temperatures exceeding 1000ºF (538ºC), and therefore heavier gauge wire is recommended for longer life at these temperatures.
Type K (CHROMELvs ALUMEL) is used in oxidizing, inert or dry reducing atmospheres. Exposure to vacuum limited to short time periods. Must be protected from sulfurous and marginally oxidizing atmospheres. Reliable and accurate at high temperatures.
Type T (Copper vs Constantan) is used for service in oxidizing, inert or reducing atmospheres or in vacuum. It is highly resistant to corrosion from atmospheric moisture and condensation and exhibits high stability at low temperatures; it is the only type with limits of error guaranteed for cryogenic temperatures.
Type E (CHROMELvs Constantan) may be used in oxidizing, inert or dry reducing atmospheres, or for short periods of time under vacuum. Must be protected from sulfurous and marginally oxidizing atmospheres. Produces the highest EMF per degree of any standardized thermocouple.
Type N (Nicrosilvs Nisil) is used in oxidizing, inert or dry reducing atmospheres. Must be protected from sulfurous atmospheres. Very reliable and accurate at high temperatures.

- Q:I want to install 110W bulbs instead of 55W bulbs on my 2003 subaru legacy so i can see better at night. the stock bulbs are not bright enough. will i melt the wiring with the extra current?
- Hotter headlights might damage the housing due to the heat as you're doubling the output. The current and wiring should not be an issue, however. Anything brighter than OEM is illegal and might earn you a ticket from local law enforcement . Parts on a car are designed to work safely. So the reason you have 55W bulbs are so as not to blind other drivers. This is something few people consider when buying auto accessories. Make sure that the headlights are aimed properly, so the proper amount of light is on the road. Brighter headlights will not solve this problem. Driving lights might be a better alternative, but make sure that they are low beams and aimed to the road and not the trees. Hella makes a good set.
- Q:I have a small John Deere tractor i keep at my lake lot. I have a big problem with rats chewing up the wiring. They have gone as far as getting into storage shed, get into the range cubes i keep for cattle feed and make a nest under the hood of the tractor.Is there any kind of electrical tape to wrap the wires with to keep them away. They chew not just threw the insulation, but even the copper wire.
- Hi there. I had the same problem near my barn The oly thingthat worked was rat traps and rat bait. But becareful whne you go to use the tractor afterwards. I forgot about a rat trap it hit the cooling fan and . bits of rat flew everywhere I have heard that tractor supply sell a spray for this but i have never been able to find it.
- Q:Wire red line green line, which is the zero line and the line of fire?
- In fact, electricity in the red and green are all FireWire, but in 220 volts together with the general default for the red line of fire, but still have to measure the specific, because not all of the electricians are the construction of this
- Q:help! i have been searching but counldn't find the inventor HELP!
- Wire was around before Edison, he invented the phonograph. He couldn't have done it without wires. Ben Franklin invented the lightning rod, I guess you could consider that the first use of an electrical distribution method.
- Q:I have a problem, i have bought headphones multiple times they die out way to fast because when i wrap up the wire around my Mp3 the wire loosens up because it gets slightly tugged on, now can you tell me some solutions to this, besides wrapping it up loosely!
- There is no solution other than that. The inside of earphone / headphone cables is copper wiring, and after constant bending and straightening (much like a normal piece of metal) it will snap. This causes the sound to cut out and cut in as sometimes the snapped edges will still touch each other to pass the electricity through and sometimes won't. Only advise is to not wrap them so tightly as copper wiring isnt very durable. Maybe try and get a case that keeps them wrapped loosely.
- Q:i have to do all 20 chapters and I was wondering if there was a site where I could find all the answers for each chapter and not read the book?only relpy if you know of a site that could do that for methanks
- This is a VERY scary question! Please, post your full name and address so that I don't hire you by accident to do any electrical wiring in MY house!
- Q:I want to install two separate outdoor lights. How do I do that from one wire? How can I make one wire into two wires and what would I need? Thanks.
- You need 2 wires a positiv and ground. You need a complete circut. Make sure the power is off and strip the line to see if you have 2 wires inside. if not then seek good help otherwise you might just burn your flat down
- Q:fore an electric stove of 3000 watts, taking into consideration that the voltage in my country is 220volts
- Use Ohms Law, compute the (Current + Future Load + allowance), 10% would be enough if it is a direct cable to your stove, but if you want to add more load, then you have to consider them in the calculation, and when you consider the size of wire look at the manufacturers table for the correct size. Below is the formula: PPower in Watts ICurrent in Amps EVolts RResistance in Ohms EI*R PI*E IP/E Always put a separate circuit breaker when your add something this big to your line.
- Q:Hi, I am building a greenhouse in my backyard and had a few questions as to how i should wire it. The appliances I will have in the greenhouse include.A 400 watt light.a 115 volt pump, an oscillating fanand a ventilation fanI can't remember the wattage of the two fans. But my question is will I need to run more than one wire out to my greenhouse? The wire I have says its max voltage is 600. any tips and advice would be nice.
- Many extension cords particularly are not rated for out of doors exposure. you're able to get away with it, yet a bigger way could be to purchase some form UF romex. probably 14-2 with floor would be ok for what you're doing. placed a plug on each and every end and Voila! you have an out of doors twine.
- Q:There is a group of 220V wire close to the walls of my house and live, and that side of the wall is just my bedroom bed, do not know for a long time will not cause harm to the human body? More
- . the general radiation and distance, high-voltage lines and residential safety distance: 1KV the following distance of 4 meters; 1-10KV the general distance between the radiation and distance, Distance of 6 meters; 35-110KV distance of 8 meters; 154-220KV distance of 10 meters; 350-500KV distance of 15 meters; . as long as the opaque objects can block the wire radiation, wire insulation, Body will block the radiation.
