Product Overview
The Honeywell HEL-700 Series Thin Film Platinum RTDs are designed for critical temperature monitoring and control in industrial applications. These sensors offer a linear change in resistance versus temperature, providing high linearity, stability, accuracy, and a wide operating temperature range in a compact, fast-response package. Manufactured with a thin layer of platinum on an alumina substrate, they are laser-trimmed for precise interchangeability and come as fully-assembled, ready-to-use elements. Available with TFE Teflon or fiberglass-insulated lead wires, they are suitable for a broad spectrum of industrial, medical, aerospace, and defense applications.
