RTD Elements

RTD Elements

RTD sensor elements are the temperature sensing component that changes in resistance based on changes in temperature. These elements are the core technology of RTD probes and assemblies

There are two basic types – Thin film elements where the specific metal materials (platinum and nickel primarily) are deposited onto a high puirty alumina (ceramic) substrate and resistance pattern is created through photolithography, etching and laser trimming

Wire-wound elements where a thin platinum wire is wrapped and fused inside a glass casing or embedded in ceramic.
