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.
