ABSTRACT The in-situ observation of pressure inside a sample chamber was made by exploiting the piezoelectric effect in manganin wire. This was done by considering temperatures of room temperature (±1°C), 600°C (±3°C), and 900°C (±3°C), pressure range of 0–2.4 GPa (±0.1 GPa), and the inferring a relationship between the relative resistance of manganin wire and the pressure inside the sample chamber for the different temperatures, allowing the pressure to be found.

锰丝压力表在高温条件下大容量压力机中的应用

摘要 利用锰丝的压电效应，对样品室内的压力进行了原位观测。这是通过考虑室温 (±1°C)、600°C (±3°C) 和 900°C (±3°C) 的温度，0–2.4 GPa (±0.1 GPa) 的压力范围来完成的，推断不同温度下锰丝的相对电阻与样品室内压力的关系，从而求得压力。
