Abstract

The most commonly used pressure sensor is the manganin gauge. It is particularly useful at room temperatures and for truly hydrostatic conditions. However, at low temperatures it has two main drawbacks: strong Manganin resistivity dependence on temperature and high sensitivity to nonhydrostatic stresses (1) (2). Especially, the second drawback is very serious because, in the pressure range up to 15 kbar and at temperatures below 77K, the non-hydrostatic stresses can not be completely eliminated.
