Multiple RuO2-chip thermometer for applications in 0,02—30 K range



A multiple RuO2-chip thermometer based on commercial Vishay RCW575 chips for applications in 0,02—30 K range is proposed. Possible design and packaging of the sensor are suggested. Thermometer saturation and thermal resistance of our sensor are measured and compared with a single-chip configuration and commercial Lakeshore ROX-102A thermometer.
