A thick film RuO2 chip sensor mounted in a gold-plated copper holder. RuO sensors work by measuring the resistance to the flow of electricity, which increases as the temperature of the metal increases.
The thick film RuO2 chip sensor has been mounted in a gold-plated copper holder. The holder is designed to give a good thermal contact between the sensor and the object of interest while also minimising the mechanical strain on the sensor. Such a strain can cause the calibration to change after thermal cycling.
The thermal time constant of the sensor (determined by its heat capacity and thermal resistance to the holder) increases as the temperature drops, and may be several minutes at the lowest temperatures.
This sensor is generically calibrated with a temperature range of 50mK - 4.2K.
Sensor is wired using four 0.20mm diameter (36 SWG) polyester enamel coated copper wires, a pair each for the excitation current and measured voltage.
