HEL-716-U-0-12-00 Platinum Resistance Humidity Temperature Sensor Thin Film

Product Description:



HEL-716-U-0-12-00 700 Series Thin Film Platinum Resistance Temperature Detector



Features:

HEL-700 Series Thin Film Platinum RTDs (Resistance Temperature Detectors) are designed to monitor or control critical

temperatures in industrial applications. 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.
