SI Temperature Probes for Cryogenic field Amar B Karki Scientific Instruments Inc Email: akarki@scientificinstruments.com Abstract Measurement of Physical properties such as temperature, pressure, density is key to the Industries, Medical facilities, Space Shuttles and Research Institutions. Since 1967, Scientific Instruments (SI) has been a leader in the production of instruments such as Temperature probes and Density meters. SI is committed to our goals and vision to be the worldwide leader in cryogenic measurement technology through continued innovation and advancements in technology. In this presentation, I will discuss on the SI products and selection of a suitable sensor based on application, temperature range, sensitivity, response time, stability, and packaging. Ruthenium Oxide Temperature Sensors are thick film resistors which adhere to are available with calibration down to 20mK or grouped/interchangeable. The ruthenium oxide temperature sensor offers excellent performance characteristics in magnetic field environments. The SI Silicon Diode Temperature Sensors operate over a wide temperature range (1.5K to 500K) and are miniature in size. They are linear over a wide temperature range interval, have high sensitivity in their lower range, and are interchangeable to a standard V/T curve. We recently introduced Zirnox sensor which is made of a thin film of zirconium oxynitride. This is a resistive temperature sensor that can operate over a wide temperature range (20 mK to 420K), exhibits negligible calibration shifts when exposed to magnetic field and ionizing radiation environments. SI 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 SI-7000 LTD is the most dependable solution for level, temperature, and density profiling in LNG & LPG Storage Tanks.
