The dynamic cumulative error of the ICS-17A type electronic belt scale is less than ±0.5%. It is applicable to the weighing process control in industrial enterprises, such as detecting the production volume, controlling the quantitative loading of products and monitoring inventory, etc. It provides important data information for the automatic control and modern management of the factory.
Working Principle
The weighing bridge is installed on the conveyor frame. When materials pass through, the weighing idlers detect the weight of the materials on the belt conveyor. Through the action of the lever, a voltage signal proportional to the belt load is exerted on the weighing sensor. The speed sensor is directly connected to the large-diameter tachometer roller, providing a series of pulses. Each pulse represents a unit of belt movement, and the frequency of the pulses is proportional to the belt speed. The weighing instrument receives signals from the weighing sensor and the speed sensor, and through integral operation, obtains an instantaneous flow value and a cumulative weight value, which are then displayed respectively.
System Composition
The ICS-17 type electronic belt scale is composed of four parts:
ICS-17 type weighing bridge: The ICS-17 type weighing bridge is equipped with four sets of idlers on the double levers. It is supported by two tension-type sensors in the middle, and the outer support adopts a frictionless trunnion pivot. This effectively overcomes the impact of eccentric loading on accuracy. This enclosed device can prevent vibration, moisture, corrosion and material accumulation, thus avoiding the problems caused by the use of knife-edge devices and bearing devices in harsh environments. The main beam of the weighing bridge adopts a rectangular steel pipe, which endows the entire weighing bridge with sufficient rigidity, a relatively small self-weight, and minimizes the area of surface dust accumulation. To ensure the stability of the entire system, high-precision strain gauge sensors are installed in the tensioned parts to reduce non-linear errors.
