介绍了一种用于低温磁化率和电阻率测量的简易夹持式压力仪的设计。该电池由WC活塞和经过自紧处理的Be-Cu圆柱体组成，样品腔由聚四氟乙烯桶和电极塞组成。在300K~77K温度范围内，用由BiI→II室温转变压力标定的锰铜压力计测量压力，并考虑了锰铜电阻压力系数随温度的变化。结果，该电池能够在室温下产生高达30kbar的静水压力，在4.2K时至少产生高达25kbar的静水压力。
A design of simple clamp type pressure apparatus utilized for measurements of magnetic susceptibility and electrical resistivity at low temperatures is presented. The cell consists of WC piston and Be–Cu cylinder which was autofrettage processed, and sample cavity consists of a teflon bucket and an electrode plug. In a temperature range from 300 K down to 77 K, pressure was determined by manganin gauge which was calibrated by Bi I→II transition pressure at room temperature and also the temperature dependence of pressure coefficient of manganin resistance was taken into account. As a result, the cell was capable of generating hydrostatic pressures up to 30 kbar at room temperature and at least up to 25 kbar at 4.2 K.
