Product Description:

NiCr-NiSi (Type K) thermocouple finds the widest use in all basemetal thermocouple, at temperature above 500℃。The main chemical composition of  positive leg NiCr (KP) are Ni≈90% and Cr≈10%; negative leg NiSi (KN) are Ni≈97% and Cr≈3%. The operating temperature range is -200~1300℃(for short term) and 0~1100℃( for long term)。

Type K thermocouple has strong resistance to oxidation than other base metal thermocouples. It has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in the following cases:
(1) Alternatively oxidizing and reducing atmosphere,
(2) Atmosphere with sulphur gases 
(3) Long time in vacuum
(4) Low oxidizing atmosphere such as hydrogen and carbon monoxide atmosphere

Q:Is the POE switch connected to the network camera via the patch panel to affect the power supply function?
Recommend you look at this: wire gauge wire diameter table
Q:What is the safety distance between the bridge and the bridge?
This is the middle school physics it The birds will short the wires between the feet, but the distance between the feet is too small, the voltage is small, the current flowing through the bird body is small; but if it is the distance between the two people as long as possible hanging on the wire , Maybe electric shock. I have just learned to trouble points, thank you
Q:1 square wire can load how much power
You remember, a square of the copper core line can not allow more than 8A of the current through it, under normal circumstances, we take 5 to 6 years of current to count, remember too much, and trouble, only Disrupting our memory. This value is applicable in low voltage
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:The cross - sectional area ratio of the cable to the embedded tube
FireWire is red, the blue line is blue. Ground is yellow and green. Three-phase socket, usually on the left and right to the right fire. Usually we will phase the current phase difference of 120 degrees wire called FireWire. Three-phase power of the three tail together called "zero line". The ground wire is the line connecting the earth to the earth.
Q:0.5 square feet can bring the number of watts
No. You can also terminate the data module. With five lines, five modules to achieve five types of rate; with six lines, six modules to achieve six types of rate. 110 patch panel can terminate the data module, RJ45 network patch panel can also transmit voice.
Q:Why some cable tray to spray, what is the role?
The state does not specify that small plastic lines are generally 100 meters in packaging. The other looks at the size of the disk and the customer's own needs.
Q:50pe threading tube how to connect, such as to be buried 50 meters PE pipe, the connection between each pipe how to do, with what materials or tools.
If there is a group of two groups of weak lines, in order to prevent interference, should be more than 200mm distance, the specific requirements should be based on the scope of electromagnetic fields.
Q:A few days without using the boot button to press the reaction did not open the computer
Three-phase power of the power, voltage, current relationship between the three P = 21.732UICOSφ, COSφ is the power factor calculated by 85%, calculate the current and then according to the current selection cable, blue load can be checked on the Internet can also consult the cable manufacturers
Q:10KV high-voltage cable and heating pipe cross the safe distance
And the thermal pipe ditch parallel to the distance of 2 meters, the special circumstances can be reduced and reduced by half the value; cross-distance 0.5 meters, separated by a partition or cable pipe can be 0.25m see GB-94 Table 5.3.5 2006 version of the basic out or the implementation of this, to the local power supply management advice prevail
