Fe-CuNi thermocouple (type J) is also named Fe- Constantan thermocouple. The positive leg Fe(JP) is made by pure Iron, and the main chemical composition of negative leg Constantan (JN) is Cu: Ni≈ 55%: 45%. Although they are all called Constantan, JN does not give the same EMF output curve as EN and TN, it cannot be instead by other Constantan.
The operating temperature range of type J thermocouple is -210~1200℃, but it is usually used in the temperature range 0~750℃ due to embrittlement of Iron.
Type J thermocouple has good resistance to oxidation and high EMF output against Platinum 67, with good temperature accuracy, sensitivity and stability. It is recommended for vacuum, oxidizing, reducing or inert atmospheres, but it can not be used in sulphurous atmosphere above 500℃.
- Q: Do the wires offer some sort of heating for them?
- For a chook , a nest isn't comparable to a three-mattress room ranch -- it is a place to maintain eggs and toddlers secure till they are grown. So nests are basically used while birds are having toddlers. while a grownup chook has toddlers to guard, it is going to return to its nest and sleep in it. yet something of the time they are able to sleep everywhere they like. Many birds sleep perched on branches, far removed from maximum predators. Others sleep status on the shore, or whilst floating interior the water, or maybe whilst flying! How do they take care of that? maximum birds can permit a million/2 their brains sleep whilst the different a million/2 is unsleeping!
- Q: I added a doorway in a wall that had wiring for my baseboard heaters. There are three heaters on the circuit. I used 12/2 wire to splice. Now the heater next to the splice works fine but the heater in the next room on the same circuit barely warms up and only when the heater next to the splice is not on. The original wire looks larger than the 12/2 I used to splice. It is the same romex shape but stiffer. Could this be 10/2 wire? The breaker is 20 amp. Could this be why the heater at the end of the circuit barely warms and only when the other heater is not on? Solution??
- most likely its voltage drop caused by using wire that is too small. it is likely that due to the load on the circuit, there is a significant amount of voltage drop due to the resistance of the #12 wire. use #10 and you'll see the voltage increase of course, this is assuming that the voltage is too low. if they worked fine before the splice, thats all that I can imagine has gone wrong, unless it is just coincidence
- 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?
- Halo. I do this line do not ask me also ran here to ask .. no problem .. it is best to use the best iron soldering .. no welding does not matter. Effect is not bad!
- Q: i have a 1981 honda express (nc50)and i'm trying to read the wiring diagram
- The circuit you have given is for the ignition. The symbol is for an SCR (silicon controlled rectifier). Triggering the SCR with the coil in the flywheel causes the SCR to discharge the capacitor through the ignition coil. Once discharged the capacitor (also called a condenser) discharges below the sustaining current of the SCR and commutates (ceases conducting) ready for the next charging pulse.
- Q: Hello,In the rental cottage that I live in, I have an enclosed back porch that doesn'tt have any electrical outlets. What I do have is a vent opening for the furnace room which is on the other side of the wall. This is a short vent, and once inside the furnace room, it is just a few feet to an electrical outlet. Since I am renting the place, I figure the most non-invasive way to get electricity out to the porch is to feed an extension cord through the vent. One catch is that I put a screen on the vent because otherwise moths and bees were flying into the house. How can I install the extension cord, through the screen, and reseal the screen so I can stay bug-free inside?thanks much
- careful, the heat from the furnace vent could melt the insulation on the wire.
- Q: I have an electrical switch that controls a recessed light. I need to move the switch, taking down the wall it is on. My questions is, why are there three wires in there? I understand that one of them is for power into the switch, 2nd one for power out to the light not sure what the third one is for? It is almost impossible for me to trace the line as it goes up into the ceiling.
- Sounds as though you may have a two way switch to a lamp controlled by another switch in a different location but you don't say colour codes so difficult to be specific
- Q: Hello, since last Saturday, our furnace was producing some burnt smell. It is on occassional basis but it's been happening until today (2 days). It's on and off. Can you please advise what is the problem and suggest my next step.Thanks
- If you are smelling any thing burning call your local electrical contractor, heating contractor, and have it checked out. You could be left without heat in your house or worse, an electrical fire. DON,T PUT IT OFF!!!
- Q: I have a crap signal coming downstairs from my wireless modem upstairs. I was looking at buying a better wireless modem when the guy redirected me to this thing that you plug into your electrical outlet, and then there's a receiver to plug into an outlet near the second computer. He claims that it sends a far better signal than wireless because it sends the signal through your houses electrical wires.Anyone have any experience with it? Is it good? Also what's it called because I'm having a heck of a time looking it up online lmao.
- Ethernet over power line adapters They are better than wireless, when they work. You have to use the outlets directly, you cannot use power bars or extension cords with them. Some have issues when on different sides of the power lines (each half of the 240V). Just try different outlets if having issues.
- Q: How does electrical field spread through the wire when there is potential difference on its edges?
- as current flows
- 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
- think of of it like the bypass in a circulate. the present is the bypass of electrons and the resistance is the resistance to this bypass, like an impediment blockading the path of the water.
