TLDR
In this article, a mass measurement system using the self-excited oscillation of a nonlinear system is developed, which contains an on-off relay with dead zone and switches force acting on the object in relation to the position.Abstract:
Concerns mass measurement under conditions of weightlessness. A mass measurement system using the self-excited oscillation of a nonlinear system is developed. The system contains an on-off relay with dead zone and switches force acting on the object in relation to the position. The mass of the object is determined from the time interval measurement of the on-state and off-state periods. The measurement accuracy is experimentally studied.read more
