FIELD: agriculture mechanical engineering.
SUBSTANCE: system comprises pickups of speed of rotation connected with the unit for measuring speed of rotation and piezoelectric pickups of loss connected with the amplifier-generator. The unit for measuring speed of rotation is connected with the unit for light and sound alarm through the unit for control of speed of rotation. The amplifier-generator of loss pickups and amplifier-generator of the pickups of tension of chain and belt drives are connected with the loss and tension indication unit through the switch provided with a set of resistances.
EFFECT: enhanced reliability.
