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: Upstairs toilet water seepage for a long time, my house is a large number of walls, has been unable to discuss the argument, the recent short circuit, and suspected to be the reason for water seepage, but upstairs and his insistence, even if there is a leaking can not affect wire. Because of this ignorant, so here to ask you, leakage of water will lead to short wire inside the wall? Thank you for answering. Question added: 1: is the old house, the wire is replaced seven years ago. 2: upstairs tenants insist on not admit leaking, but also invited his decoration master to see, they say no matter what the situation, even if the water leakage will certainly not lead to short circuit. For his argument doubt, so I would like to ask, is not any case, the leakage of water will not be inside the wall bubble to a short circuit? More
- If your wire in the thread when the insulation will break even if it is a little bit, or the existence of quality problems with the wire encountered when the water or moisture will cause a short circuit. (Upstairs tenants do not admit that the water is not admitted, but also invited his decoration master to see, they say no matter what the situation, even if the water leakage will certainly not lead to short circuit.) Is his decoration master? Funny right? First of all, you have to find a professional electrician master to let him use [shake table] or megger to detect whether the line there is a short circuit phenomenon, if there is upstairs in the upstairs and then check, and then consult.
- Q: My instant electric water heater is 4500 watts need to use the number of square wire electrician said 4 square wire can I see a lot of people say that the 6 square of the job Will you 4 square line can withstand it? Question added: how can we know that the line is the national standard or non-national standard ah line is the original developers to help me installed a 4 square does not know is not how to identify the national standard?
- Extension line, plus a pair of joints just fine, and only added the connector will not affect the signal
- Q: Can anyone help me out! Does it have any ruled for electrical wiring? i know like the Neutral Wirer always goes to the light. The Live wirer should go to a switch. Does it have any more tips for me?
- Precisely what do you need to know? Is it a three way switch? A single pole switch? At home or at work? Different methods can be used in commercial buildings than residential work.
- Q: Hi, My house has a wire for a light sticking out of the wall on the outside of the house. Problem is that there is no electrical box, so I have nothing to mount my light too. The outside is wood. Does anyone have any suggestions, that will work, and is safe? Thanks for your timepb4sc
- install a water tight box. then install light on box. tools drill,screwdriver,screws,drill bit
- Q: What is the difference between YC and YZ cable?
- Most of the current use of CPVC, PVC as the base material, into other polymer materials to improve the high toughness of the high-voltage power cable sheathing. Mainly used for cable laying to guide and protect the cable when the role. State Grid Corporation of the team to answer your questions, I hope you can help!
- Q: I'am going to put in baseboard heat in my basement,the unit I want to put in is 240 volts 1000 watts, what size wire should I use or can I run 2 12-2 lines from 2 differnt lines?
- As the other electricians have said (and I am one also), you need one 12/2 cable connected to a new 2-pole 15 or 20 amp breaker in your panel (the black goes on one terminal and the white on the other). You can't hook it up to two separate 120volt breakers or circuits -- not safe and not to Code. And you need to tag both ends of the white wire with red or black tape to identify them as line wires and not neutrals.
- Q: Does anyone know of any places that offer emergency electrical wiring assistance in Florida for the low income? I own my home and live in Lakeland but this home was built in 1970, my electrical socket in the living room shoots sparks the circuit panel is old and a bit rusty and shot sparks last night my lights go out just about every other day for short periods of time I dont know what to do and cant seem to find help if anyone knows anything PLEASE let me know, im so scared im going to come home to a burned down house im so poor i cant even afford homeowners insurance so im in a bind!
- Try just shutting of the circuit breaker to that part of the house until you can afford to have this fixed. That is the safest solution.
- Q: i dont know if this is to confusing to understand but i was jw if i could make heat using electricity and electrical wiring that can stay warm and can heat things up and that is rechargable that i can put in a coat or anything fabric or shirts or shoes can anyone help me out with this?
- There are electrically heated garments, (motorcycle gloves eg.), but you couldn't comfortably carry enough rechargeable batteries to make it practical, (yet), to heat your whole body for more than a few minutes.
- Q: I have a spot in a room where there used to be track lighting. I'm going to be moving the electrical to the center of the room for a fan. Can I just used wing nuts and add to the existing wiring - will that be ok hidden behind the ceiling sheetrock? I need to add about 8 feet of wire to the center of the room from the current spot.
- What JakeB said is right. Or find where the wires are coming from that went to the track light. Use the old wire to pull new longer wires in its place reconnect the new wire ,remove the short old wires and then wire up the fan.
- Q: I have a '49 ford truck, w/350 v8 Chevy engine. The fan is currently hot wired straight to the battery. How do I connect it to the ignition so the fan goes off when I shut off the engine?
