Honeywell HEL-700 Thin Film Platinum RTD Sensors

Honeywell HEL-700 Thin Film Platinum RTD Sensors are built to monitor and control critical temperatures across industrial systems. These sensors offer a linear resistance change with temperature, providing high linearity, stability, accuracy, and a wide temperature range in a compact, fast-response package. The HEL-700 thin film platinum RTD sensors offer a maximum operating current of 2mA and have an insulation resistance greater than 50MΩ. These devices feature a durable cylindrical alumina package with TFE Teflon or fiberglass-insulated lead wires. Typical applications include HVAC equipment, process control, battery packs, autoclaves, aircraft, and space vehicles.
