ETC 2PT100

2 Pt100 KN 3026
The KN Series Ceramic Wire Wound PRTDs are suitable for
general applications requiring temperature stability. The
dual sensor can be used in redundancy systems.
1
Applications: Industrial resistance thermometers, especially
in chemical, power generation plants and analytical
equipment.
2
Construction: Two separate platinum coils are embedded
and sealed inside a high purity aluminum oxide ceramic
body. Lead wires are shear force resistant and assure proper
connection to extension leads and cables.
