Чем измерить скорость вращения винта?
Подскажите как это сделать на катере?
Подскажите как это сделать на катере?
поставить датчик на маховик оптический или холла, а дальше или мерять на месте частотомером, или на ходу активной или пассивной телеметрией типа этой
это пассивная только накапливает данные на борту www.eagletreesystems.com/MicroPower/micro.htm
это активная, пишет на борту и передает по радио www.eagletreesystems.com/Plane/plane.html
у меня такая на лодке стоит, удобная штука но дорогая
