BEL-705-U-1-12-00 Temperature Sensor
Details
The BEL-705-U-1-12-00 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 BEL-705-U-1-12-00, is designed to measure temperatures from -75℃ to 540℃[-100℉ to 1000℉] 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℃ accuracy) or optional ±0.1% (±0.3℃ 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.
