Description Indus manufactures Electronic Gravimetric Weigh Feeders incorporating state-of-the –art technology for continuous bulk proportioning of solids. The material to be proportionally fed is passed over the belt; flow rate (also cumulative value) of the material is measured and compared with set parameters of the PLC/PID controller. The deviation is corrected by regulating the speed of the conveyor through variable speed A.C.Drive. (closed loop control system)Two high precision load cells are used to measure the belt load & a rotary encoder used to measure speed of the conveyor. Salient features Precision machined rollers used to provide perfect belt run & high accuracy Rubber coated pulleys prevents belt slippage. Gravity takes up to ensure constant belt tension Scrappers to prevent belt damage & tare changes Easy maintenance - belt change without aids from side Fully automatic Zero/Span calibration Highly reliable PLC (with in built PID algorithm) & variable speed AC drive High precision load cells with damping to obtain best results. Empty Belt Correction Factor to achieve best Accuracy Set Points Programmable from local panel or Main Panel Option Features Rs 485 Interface can generate printout with SQC Analysis Applications Cement, Sponge Iron, Steel, Fertilizer, Chemical, Tobacco & Petrochemical Industries.
