3. System composition, working principle and characterist of ICS belt scale
3.1. System composition
ICS series electronic belt weigher has four parts: weighing bridge, weighing sensor, speed sensor and integrator.
3.2. Basic working principle
The weighing bridge with load cell is installed on the longitudinal beam of belt conveyor. The weight of material on the belt is detected by the load cell support bridge and weighing roller, and a signal proportional to the belt load is generated; At the same time, the speed sensor generates a series of pulse signals, each pulse represents a belt length, and the pulse length is proportional to the belt speed. The integrator uses the integration method to calculate the belt speed and belt load, and converts the two signals into digital quantities, and displays the instantaneous flow and accumulated weight on the display.
3.3. Characters
3.3.1. The weighing bridge has simple structure and less force transmission steps. Its unique lever design makes the surface area gray to the lowest; Because of the adoption of friction free trunnion fulcrum, shockproof, anti-corrosion, dust-proof, maintenance amount is very small, site installation is simple and convenient; The design of lateral force and horizontal force makes the belt deviation have little influence on the sensor; The high strength rectangular steel has good steel properties and small deformation, which ensures the bearing force and long-term stability of the scale frame.
3.3.2. The weighing sensor is buried and installed in a concealed way, dust-proof, waterproof, double-layer sealed, long life and good stability.
3.3.3. The speed sensor is connected to the speed measuring roller, and has large contact area and large angle, which can eliminate the error caused by belt slipping.
Computer integrator, for intelligent operation, digital processing parts and accumulation aspects contain the best drift free stability, all data instructions are simply sent through the panel, easy to operate.
3.3.4. It has the functions of automatic zero adjustment, automatic calibration, self diagnosis and treatment of fault, and has the function of automatic zero automatic tracking.
3.3.5. It contains the function of hanging code, chain code and physical calibration and power failure data maintenance.
3.3.6. The integrator has wall mounted, embedded, and can be selected arbitrarily; The outer surface of the shell is sealed, dust-proof and corrosion-proof.
