Model RO-600(1KΩ) – Ruthenium Oxide RTD – RuO Thermometer from Scientific Instruments
The Model RO-600 Ruthenium Oxide Temperature Sensors are thick film resistors which adhere to are available with calibration down to 20mK or grouped/interchangeable and have a nominal resistance of 1,000Ω at ambient temperature. The ruthenium oxide temperature sensor offers excellent performance characteristics in magnetic field environments. These sensors exhibit an initial small negative magnetoresistance at temperatures below 250 mK at low fields (less than about 1.5 Tesla). The magnetoresistance then becomes positive at larger fields and increases at lower temperatures. This magnetoresistance is repeatable. For example, a resistance change of 8% induced by an 8 Tesla field at a temperature of 80 mK corresponds to a temperature error of 7 mK.
No orientation dependence of sensor mounting to field direction has been observed. Ruthenium Oxide sensors are available as uncalibrated, grouping, or calibrated units and feature good reproducibility, fast thermal response time and miniature size, all at a reasonable cost.
