Product Description:

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.


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:Anyone know about the electrical wires on a 1981 Ford F-100?
The two large cables, one goes to the battery, the other goes to the starterThe two small wires, one goes to the start connector at the IGN switch, The other goes to the coil as a direct 12v for better spark for starting. ( when you release the key from start to run the 12v supply goes to the coil via a resistor wire) This set up assures better spark for starting.
Q:how to keep my kitten from chewing electrical wires that are plugged into outlets?
get her something else for her to chew on!! this happend to me my kitten kept on chewign wires behind the tv so i bought her a scatch post and a few toys and she soon stoped chewign on tthe wires good luck hope i helped :D xx
Q:Electrical wire visible to receptacle?
No you can't run it exposed Thats what is called exposed to physical damage and has to be protected, and for the fella saying it may be BXHAHA! The outer jacket of BX IS NOT a Ground!! Back when BX was used they used 2 prong outlets, Hence NO GROUND! If you don't know Electrical work, Call an Electrician and don't give recommendations that you are clueless about!
Q:Home wiring and electrical question?
With respect, you have mis-wired somewhere. Old Outlet Box is A New Outlet Box is B Switch Box is C Light is D A (hot)--------------------------- B (hot) ------------------------------------ C / --------------- D (hot) A (neutral/common)-------- B (neutral) ---------------------------------------- D (neutral) A (ground) -------------------- B (ground)------------------------------ C (ground)------- D (ground) As to a 3-way switch, in the switch box, the hot goes to the copper-colored screw, the leg to the light goes to either of the brass-colored screws. The neutral goes straight through the switch-box. Only the HOT gets switched. The ground is connected to all three new devices but is continuous. If this is not crystal-clear, call an electrician.
Q:How to solve the USB cable is too long power shortage problem
This is not to say if the motherboard power supply voltage is not possible to burn the board actually go to the computer city to buy a 6PIN switch 8PIN adapter should be able to
Q:How do I rewire this mess?
If you have to ask, then you need to hire an electrician.
Q:Does electrical house wire have an expiration date?
For new house wiring ? Probably not now. At one time house wiring was bare - it had no continuous insulation and was strung individually on glass-like support posts. That system had a name which I cannot remember. Some may be yet by existing today if the residence has not been inspected. Then wires were individually insulated with paper or cloth wrap which will deterrioriate . Those are also to be found still in service in houses built in the 1920 -30s. I have seen it. When plastic became commonly available the duration of the continuous wire insulation greatly improved and modern wire insulation could be implied to have a reasonably unexpirable duration in residential and commercial service. However, it is not so stamped because of factors beyond the reasonable control of the manufacturer.
Q:What could've made an electrical wire in my attic burn?
Call a qualified professional electrician to inspect your wiring make any needed repairs. You need to do this for your peace of mind. More than likely the burn is caused by an overload which is very dangerous and can cause a fatal house fire. Call an electrician now.
Q:How can I wire solar panels into my homes electrical grid?
Rudydoo is the only one I completely agree with, here. It is not necessary to use batteries with a modern grid-tie (grid intertie) inverter. With electrical experience, you could hook it up yourself, but would have to be experienced enough to get into the service panel, which can sometimes source 4000 amps if you were to shunt it above the main breaker. Be sure you know what you're doing. It also generally requires permission from your local power company, and almost everywhere, permits (might be inexpensive, depending where). Also, in some countries, a homeowner is prohibited from doing a self-install. This is not true in most parts of the US, but might invalidate some state incentives, depending on where you live. Also, it's not generally worth connecting just a panel or two, unless you're in an area that has a high feed-in tariff.
Q:I put the computer on the TV but showed no signal
(Including PVC, insulation, etc.), insulation sheath (same as the power cable, or control cable, or signal cable, copper wire or aluminum wire), insulation (including PVC insulation, Insulation), applicable objects (such as marine, explosion-proof area) and the cable cross-sectional area and the number of cores.
