DT-470/471 Hermetically Sealed Silicon Diode. The DT-470/471 Silicon Diode temperature sensors incorporate remarkably uniform sensing elements that exhibit precise, repeatable, monotonic temperature response over a wide range. The elements are mounted into rugged, hermeticallysealed packages that have been specifically designed for proper thermal behavior in a cryogenic environment. The result is a family of sensors with temperature characteristics so predictable, tightly grouped, and stable that the sensors in most applications are routinely
interchangeable with one another.
