Product Overview
The Honeywell HEL-700 Series Thin Film Platinum RTDs (Resistance Temperature Detectors) are engineered for critical temperature monitoring and control in industrial settings. These sensors offer a linear relationship between resistance and temperature, delivering high linearity, stability, accuracy, and a wide operating temperature range within a compact, fast-response package. Designed for temperatures from -75 C to 540 C [-100 F to 1000 F], the HEL-700 Series features fully assembled, ready-to-use elements that eliminate the need for fragile splices. Manufactured with a thin platinum layer on an alumina substrate and laser-trimmed for precise interchangeability, these RTDs are glassed, wired, and potted or ceramic fired into a cylindrical alumina package with either TFE Teflon- or fiberglass-insulated lead wires. They are suitable for a broad range of applications including HVAC, process control, motor windings, battery packs, ovens, kilns, autoclaves, aircraft, and space vehicles.
