 A disadvantage of the known device is the low accuracy of the results when weighing in zero gravity.

 The objective of the present invention is to improve the accuracy of determining mass in zero gravity.

 The essence of the invention in the first embodiment is that the device for determining the mass in zero gravity contains a rod, a plate for fixing on the said rod of the measured mass, a support pipe, which is perpendicular to the said rod, as well as a rotation unit designed to create centrifugal force, consisting from an electric motor and an electric power source. Additionally, it is equipped with a rod on which the support tube is located, calibrated springs, removable support rings, rulers having divisions, which are designed to be located on said rod to determine the mass value by the state of compression of the said springs.

 The essence of the invention in the second embodiment is that the device for determining the mass value in zero gravity contains a rod, a plate for securing the measured mass on said rod, a support tube which is perpendicular to said rod, and also a rotation unit for creating centrifugal force, consisting from an electric motor and an electric power source. Additionally, in the second embodiment, the device is equipped with a rod on which the support tube is located, removable support rings and load cells, which are located on the said rod and are designed to determine the mass value.

 Calibrated springs and strain gauges are elastic elements, the deformation of which determines the value of the determined mass.

 FIG. 1 - device with calibrated springs.

 FIG. 2 - device with load cells.

 In the first embodiment (Fig. 1), the device for determining the mass in zero gravity contains a rod 5, one plate 1 for securing the measured mass 9 on the said rod 5 and another plate 1 for securing the reference mass 10 measured on the Earth, support pipe 4 , which is perpendicular to said rod 5, and designed to create centrifugal force, a rotation unit consisting of an electric motor 12 and an electric power supply 13. Additionally, the device is equipped with a rod 3, on which is located the aforementioned support pipe 4, calibrated springs 7, removable support rings 8, rulers 6, having divisions, which are designed to be located on said rod 5 to determine the mass value by the state of compression of said springs 7.

 In the second embodiment (Fig. 2), the device for determining the mass in zero gravity contains a rod 5, a plate 1 for securing the measured mass 9 to said rod 5, a support pipe 4, which is perpendicular to said rod 5, and also designed to create centrifugal force a rotation unit consisting of an electric motor 12 and an electric power source 13. Additionally, in the second embodiment, the device is equipped with a rod 3 on which the support tube 4 is located, removable support rings 8 and strain gauges 6, 14, which are located on the said rod 5, are connected by a wire to the slip ring 16 and are designed to determine the size of the measured mass 9.

 When the reference and measured masses rotate, centrifugal forces arise that compress the left and right strain gauges, which makes it possible to determine the measured mass by the ratio of compression forces.

 Calibrated springs and strain gauges are elastic elements, the deformation of which determines the value of the determined mass.
