INSULATED THERMOCOUPLE WIRE

  • These are the thermocouple wires insulated with some kinds of insulation materials such as vinyl, fluorine resin(the same as teflon), glass wool, polyester, and so on. We have a variety of insulated thermocouples in our stock.
  • The unit is 100 m.
  • In JIS standard, + pole is insulated with red and - pole is insulated with white.
  • Outer insulation's colors are the same as the colors of compensation wires in JIS.
  • In case of ASTM standard, the colors indicating types of thermocouples is used for + pole insulations, and red color is used for - pole insulations.
  • Please refer to Standards' colors guide
  • Types of Measuring Junctions

Types of Measuring Junctions

Exposed Type (Code: W) Mold Type (Code: M) Sheet Couple Type (Code: S)
This is the most popular type of Insulated Thermocouples.

This model is appled for chemical-solution and errosion environment. (Only for fluorine resin insulation. Applicable Temp. -200 to +200)

This type has excellent performance for measuring surface temperature on pipes and temperature in narrow space. (Only for fluorine resin insulation. Applicable Temp. up to +150)

TEST METHOD The product's measuring point is set in room temperature. Then, the response time is measured at time constant and 90% of response time after it is put in stir water and still air that have enough temperature difference with room temperature, instantly.
Response time is an average of T1->T2 and T2->T1.
