Application of barorezistor from samarium monosulfide when carrying out heatphysical experiments
Annotation
The baroresistors are semiconductive sensors of local pressure based on samarium monosulfide. These sensors have dependence of the resistance on pressure and temperature, which allows us to calculate the pressure affecting the sensor if its temperature is known. The significant advantage of such sensors is their small size, they can be located in observed object measuring pressure in different areas. Implementation of these sensors at full scale tests of high pressure vessels is described. A method using inner pressure of freezing water is used to load these vessels. The experimental data showing processes which took place in closed volume of the vessel during ice formation and pressure increase are given. Influence of the electric potential affecting the vessel at the same conditions is considered. An experiment using the sensors to measure pressure at one-dimensional freezing in moist ground was conducted. The data on two sensors located at different depths are given.
