Product Overview
The Honeywell HEL-700 Series Thin Film Platinum RTDs (Resistance Temperature Detectors) are engineered for precise temperature monitoring and control in demanding industrial environments. These RTDs 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 exceptional interchangeability, these RTDs are available with standard 0.2% or optional 0.1% accuracy.
