The HEL-707-U-1-12-00 is a 2-wire thin film platinum RTD designed to monitor or control critical temperatures in industrial applications. It provides a linear change in resistance versus temperature, combining high linearity, stability, accuracy and wide temperature range. These fully-assembled elements are ready-to-use in probe assemblies without the need for fragile splices to extension leads. This product is manufactured using a thin layer of platinum deposited on an alumina substrate and is laser trimmed to a resistance interchangeability of a standard ±0.2% or optional ±0.1%. The sensor chip is then glassed, wired and potted or ceramic fired to result in a cylindrical alumina package with either TFE PTFE or fiberglass-insulated lead wires.
