Abstract

The mass measurement of material on belt conveyor system plays an important role in industrial production. A new online weighing system with non-contract measurement is designed in this paper. By measuring the material thickness based on ultrasonic detection technology, the density variation of material on conveyor belt using capacitance sensor and the velocity of the belt using ultrasonic Doppler velocimeter, the mass of the measured material can be achieved. The experimental results show that the principle of the online system is feasible. More important, comparing with the traditional methods, the proposed method has advantages on higher reliability and precision.
