Scientific Instruments offers a variety of temperature probes that allow mounting in hazardous environments. These units are constructed of stainless steel, hermetically sealed, and the sensing element is mounted in a thermal epoxy at the tip. The probes are designed for direct immersion or thermowell applications. The basic sensing elements used in the Series 56 temperature probe assemblies, designed, and manufactured by Scientific Instruments, are the SI-540 silicon diodes. These diodes are rugged, wide-range (1.5K to 450K) sensing elements which offer excellent interchangeability to standard temperature-versus-voltage curves. This interchangeability allows a user to employ any given temperature probe assembly in his facility while using a single temperature curve for signal conditioning requirements. This model has been used for cryogenic hydrogen applications, ground support, and flight hardware. See below for detailed specifications.
