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[®] - or fiberglass-insulated lead wires. ## Key Features - Wide temperature range ## Potential Applications Temperature sensing for monitoring, compensation and regulation in: - Interchangeable - Accurate - Linear resistance vs temperature - Fast response - Laser trimmed - Ceramic case material - TFE Teflon[®] or fiberglass leadwires - Multiple small sizes - Ready-to-use, fully assembled elements ## **InduStrIaL** - HVAC equipment - Instrument and probe assemblies - Process control - Motor windings and bearings - Battery packs - Environmental chambers - Ovens and kilns - Drill holes in large objects ## **MEdICaL** - Autoclaves ## **aErOSPaCE/dEFEnSE** - Aircraft - Space vehicles Wide temperature range • interCHangeaBLe • aCCurate **2** sensing.honeywell.com ## Thin Film Platinum RTDs, HEL-700 Series **==> picture [542 x 419] intentionally omitted <==** **----- Start of picture text -----**
