FIELD: measuring equipment.
SUBSTANCE: invention relates to equipment and measuring technology and can be used for measuring directional stresses in ice. The apparatus includes a flat receiving element with an internal cavity and a pressure sensor, filled with a liquid. The flat receiving element therein comprises a replaceable connecting tube and is connected to an external measuring apparatus with a pressure sensor and a pressure gauge installed thereon and to an external compensation pressure adjuster via a splitter.
EFFECT: increase in the accuracy of measurement of directional stresses in ice, achieved by maintaining a constant sensitivity of the apparatus throughout the entire working measurement range.
