KE20L Fe/Cuni Jx 2X1.5 Iec

Norm references / Approvals

• Space-saving and flexible
• For more detailed information, see appendix T8 and data sheets

Application range

• Allows temperature measurement even in places where non-contact temperature measurement is not possible or reasonable
• The thermocouple is used to measure temperature as a part of monitoring the manufacturing process, thus the sheath material should be selected with reference to the maximum ambient temperature at its junction.
• Conductor materials (alloys): 
  Fe/CuNi (LX, JX)
  Conductor alloys are identical to thermocouple alloys
• NiCr/Ni (K, KX, KCA)
  K and KX version - conductor alloys are identical to thermocouple alloys
  KCA version: compensating alloys (for KCA: Fe/CuNi), not identical to thermocouple alloys
• PtRh/Pt (RCB, SCB)
  Compensating alloys (for RCB, SCB: Cu/CuNi) are not identical to thermocouple alloys
