Thermocouple extension wire is used to extend the thermode, that
is, the cold junction of the movable thermocouple connect with
indicating instrument to make up temperature measurement system.
Extension wire falls into two kinds; one is extension type and the
other is compensation type. The wire same with the two thermocouple
wires of the Graduation Mark, is know as the extension type. The
wire same with, formed by cooper—-cupronickel materials with
different proportion, is called compensation type.
The two kinds of extension wire, both have good property of
resistance to acid, alkali, abrasion and fire. It’s temperature
range used commonly is -25-400C. In addition, it can be used for a
long time by immersing into the oil. The extension wire complies
with GB/T4989-94-2016 standard.
The extension wire types can be divided into WC, BC,SC, RC, NX, KC,
KX, EX, JX and TX in accordance with the product type.
- K type, temperature: 200 °C ~ 260 °C-
- Insulation: ptfe
- Wire core diameter: 2 X0. 255 mm
- Wire core material: nickel chrome/nickel silicon alloy
- Color sign: red for the negative/yellow for positive.
- The K thermocouple temperature line type can be suitable for any
type of K import and domestic temperature record instrument use
