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: Air conditioning to use 4.0 square wire. What exactly does this 4.0 square wire show? Do not use words, do not understand with Mandarin.
- It means that the wire diameter of more than 2 mm above the wire can be used.
- Q: I am prepping it for a derby and accidentally cut the fuel pumps electrical wire harness thinking it was stereo or tail lights. I just want to hook it up to start it and move it to the shop where i can really tear into it. There are 4 wires. Black, purple, grey, and black w/ yellow stripe. I want to bypass the electrical connectors and just splice it into the wires that run along the drivers side floor. What color wire is what and what color do i splice it to?
- you will would desire to make certain in case you have potential and floor to the gas pump. regrettably you will would desire to drag the tank off to make certain the relationship. The helpful cord from the relay is a grey cord. the floor cord is a robust black cord. you are able to connect a attempt mild between the two terminals and turn on the significant. the sunshine could come on for extra or less 2 seconds and then pass off. Or in case you're cranking the engine, the attempt mild could be on once you're cranking. No mild,then you definately've a potential or floor concern. mild on, then you definately probable have a dud gas pump.
- Q: i am remodeling a bathroom. i see that the wiring is old. the main service panel was just replaced but the wires werent since i already have the bathroom walls opened up. i want to replace the wiring.the electrician said to use 12-2 wires for outles and 14-2 for light switches and fixtures.ok. i got that. ive been looking on diagrams that have outlets switches and fixtures and none of them tells what type of wire to use wheredo i need to bring two wires from the service panel up to the bathroom? one 12.2 and one 14.2?i have a VERY LIMITED space for more breakers and i dont want to have a breaker for just the outlet and a breaker for just the switch and fixture. i want to put the entire circuit into one breakeri read in some websites to never mix 12 wire with 14 wire. but that i should use 12-2 for outlets and 14-2 for switches. how can i do that?do i just use the 12-2 wire? also. the breaker i have for the bathroom i believe its 20 amp.
- Bathroom Electrical Wiring
- Q: I have an old house (built in 1962) and after testing all of my outlets, have confirmed that none of them are grounded. The house is made of brick, so it would be extremely expensive to run new circuits through the house. I really only need 1 or 2 outlets to be grounded so that I can protect my expensive equipment from damage. So what I wanted to know is if I could buy a spool of 10 gauge solid copper core insulated grounding wire, drill a hole through the brick behind the outlet, connect to the outlet and run the other end of the wire around the outside of the house to the main box. Would that be safe? Would it hold up to power spikes?
- Yes you can do that but you don't have to go to the box if you have metal cold water pipe. If the pipe is plastic then yes but you cpuld drive a metal stake into the ground 6 feet and ground to it. you can get grounding stakes at a hardware store or electrical supply so find out which is cheaper wire or stake. on the wire it doesn't have to be solid just #10 and daisy chain it. go from the farthest box outside to the scond box then to the Elecrtical supply. I assume you have a slab floor if not go to the basement and across to the box or attic to the box. An alternate solution is to just change the sockets and don't ground them. it is not really necessary most equipment has planned for an ingrounded socket. you change the socket so it will plug in without cutting off the ground pin. For GFI it is necessary to ground it(kitchen and bathroom). different states have different codes.
- Q: Hi everyone.We moved in a new house (not an appartment). The basement is finished. I am not usually be down there yet, so I can say it is not in use. I turned the separately partial heater down to 50 F degrees. The basement has some problem, the electric down there seems not steady. When I turn the neon lights on, it keeps blinking for the first 30 seconds. When I touch the switchers, it shocks me a little bit.For addition, my house is like 1600 square feet, 2 bed rooms, 1.5 baths. I keep the central air heater (pretty new, 2009) at 78 F degrees, and the electric bill first month came at $288 saying I used 2606 kWh for 20 days. I doubt that my basement's electrical wiring set-up is broken somewhere, so the electric leaks or wastes somehow.Questions are: Is it the first bill $288 for my house size weird? How do I test if my electrical wire set-up is not wasting my money?Thanks everyone.
- Do you have any electric heaters? The electricity is not leaking. If you have an electical leak, it is not the same as a water leak. An electrical leak will not increase your electicial bill noticeably. It will trip a breaker, blow a fuse, or cause a fire. You keep the basement at 50 degrees. this is likely the reason your neon (fluorescent lights) flicker before coming on. Fluorescent bulbs often will flicker or glow when the are cold and/or damp. If your house is noew the electrical boxes should be proerly grounded. As for the electrical shocks, they could be static electricity discharging to the grounded electrical boxes. If you are not sure, hire a reputable qualified electrician to check this out. If your house is new; keep any bills and present them to the builder only if there a fault was found in the wiring.

- Q: Can two wires be connected directly like wires?
- Generally it is not possible. The normal network cable connection is through the switch, HUB, router and other equipment conversion.
- Q: First of all, I need to know if this is a fire hazard, how it happened, and how to fix it:A couple of hours ago, a wall socket in the kitchen with an air-freshener plugged into it suddenly made a popping sound. My b/f went in there to see where the sound had come from. It was that wall socket. It had started to make a loud buzzing sound. He pulled the air-freshener from the plug and the sound stopped, but most of the lights in the apartment went out, also, my computer, the refrigerator, the A/C, only a few sockets were left working.Then, by some fluke, he asked me as I was standing in the kitchen if the stove was on. It wasn't, but I started to turn on one of the burners. As I did so, all the lights, my compurter, the A/C, etc all came back on! I turned the burner back off and everything stayed on! This is true and very strange and frightening, as we were afraid of an electrical fire from wiring gone haywire or something.
- Do you have a fuse box or breaker box in your apartment? If you do your boyfriend was playing games with you and either replaced the fuse or reset the breaker. Is the air freshener one of those that sprays into the air? Do you have a fan running that faces the outlet so that the moisture could get in the outlet? If you do that's most likely the cause of the sparking. If not, call an electrician to take a look at the outlet. It may need to be replaced.
- Q: I want to know why this happens in terms of whats going on at an atomic scale with the flowing electrons in the metallic bond. Thanks
- Because resistance increases with temperature . Dunno how this happens on the atomic scale , sorry.
