Development on Constant Temperature Slot of High Accuracy Standard Capacitor
Xiaobing He, Dongxue Dai, Jin Ping Pan, Wang Wei, Dewen Wang · 2013
Structure, material and some methods on reducing the heat transfer of special constant temperature slots are discussed. These special constant temperature slots are used in high accuracy standard capacitors, and have the resolution of 0.002°C and the fluctuation of ±0.01°C. They can reduce capacitance variance of the standard capacitors when the environment temperature changes. Then the standard capacitors are higher accuracy and better stability.
