Description:
Thermocouples are widely used to measure temperature. This works on the
thermoelectric effect; whereby a metal will generate a voltage when heated. By
taking the differential voltage generated when two different metals in the same
circuit are heated it is possible to measure changes in temperature as a change
in voltage.
In order to get an accurate measurement, expensive metals
are commonly used within the temperature probe itself. For long cable runs
however, the cost of these metals becomes prohibitive and for that reason Cable
manufacture a range of extension and compensation cables. As standard, Cable
offers Class 1 thermocouples which provide the tightest tolerance and most
accurate measurements.
Compensating
cable is of different composition to extension cable (it uses alternative,
cheaper alloys) but has a similar temperature. relationship over a limited
range, and should only be used for joining thermocouples to their measuring
instruments. It can only be used in limited ambient temperature, generally
not higher than 800℃。
Also,
compensating cable is less accurate than extension cable in terms of thermal
tolerance values (typically double).
With
long cable runs, the cable may need to be screened and earthed at one end (at
the instrument) to minimize noise pick-up (interference) on the measuring
circuit. Alternative types of screened cable construction are available and
these include the use of copper or Mylar screening.
Applications:
Thermocouple extension cable consists of conductors of the same nature as the elements of the thermocouple and which extends this to the thermocouples’ reference junction.
Commonly there are four types of insulation material for extension cable: fiberglass, Teflon, PVC and silicone. Stainless steel braided and tinned brass braided is also commonly used in the cable.
Customers from different areas possibly require different color style for the cable, all color standard are available upon request.
Competitive Advantage:
1.Our
measurement accuracy of thermocouple cable can reach the level of grade 1
2.10,000 meters without joints
3.The color-coded can meet the requirements of (ASNI, DIN, JAP, IEC ... etc)
