HSL is pleased to supply the RO-600 Ruthenium Oxide Temperature Sensor. These are thick film resistors that adhere to calibration down to 20mK or grouped / interchangeable and have a nominal resistance of 1kΩ at ambient temperature.
Ruthenium oxide temperature sensors offer 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 ~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.
Orientation dependence of the sensor mounting versus field direction has been observed. Ruthenium Oxide sensors are available as uncalibrated, grouping, or calibrated units and feature excellent reproducibility, fast thermal response time and miniature size, all at a reasonable cost.
