Thin Film Platinum RTDs HEL-700 Series Datasheet Thin Film Platinum RTDs The HEL-700 Series Thin Film Platinum RTDs (Resistance Temperature Detectors) are designed to monitor or control critical temperatures in industrial applications. They provide a linear change in resistance versus temperature, combining high linearity, stability, accuracy, and wide temperature range in a small, fast-response package. The HEL-700 Series is designed to measure temperatures from -75 C to 540 C [-100 F to 1000 F] with high accuracy. These fully-assembled elements are ready-to-use in probe assemblies, without the need for fragile splices to extension leads. These products are manufactured using a thin layer of platinum deposited on an alumina substrate and are laser trimmed to a resistance interchangeability of a standard 0.2% (0.5 C accuracy) or optional 0.1% (0.3 C accuracy). The sensor chip is then glassed, wired and potted or ceramic fired to result in a cylindrical alumina package with either TFE Teflon(R)- or fiberglass-insulated lead wires.
