DOSAGE - PESAGE WEIGHING BELT CONVEYOR TSRT OPERATING PRINCIPLE The Belt scale is weighing equipment designed to acquire continuously material flow handled by a belt conveyor and to totalize the weighed weight. The totalized weighed material on the conveyor is the integral of material weight per meter and the belt speed. The material weight on a belt length called “weighing length” is detected by a load collector equipped by one or two strain gauge load cells. The belt speed is measured by an incremental encoder or an inductive senor fitted on the conveyor driven pulley. COMPOSITION AND CHARACTERISTICS The SRT belt scale has been designed by SAUTELMA ROTOLOK to meet the high accuracy required by its customers. The system include one or two weight collection systems incorporating each 2 parallel sets of flexures supported by a single or double strain gauge load cell. The design of the weight collection system ensures that the weight is transferred correctly into the load cell, to optimize the weathers performance. The SRT belt scale can be of the single idler type or of the two idler type (SRT/1R and SRT/2R). La bascule SRT peut être de type simple rouleau et double rouleau (SRT/1R et SRT/2R) Elle se compose de 3 parties principales : One weighing structure (load collector) of the SRT type One or two high accurate strain gauge load cells and one belt speed detector One electronic equipment for data processing and control Weighing structure with one or two weighed idlers stations. Robust design in Carbon steel Stainless Steel manufacturing in option Local data processing (weight, speed), via DPU (Digital Processing Unit) When digital sensors are used, the signal is directly processed by the Minismart MINISMART weighing digital electronic controler made of a central unit board with 16 bits micro-controller, digital and analogue inputs/outputs and various communication ports (serial connection, USB ports, Can open…) Strain gauge load cells, IP 67, stainless steel. Depending on types and belt width, the belt scale is equipped with one or two load cells. High resolution speed sensor by incremental coder. The SRT belt scales can also be supplied with a proximity sensor fitted on the conveyor driven pulley. AVANTAGES Simple, robust and compact equipment that can fit easily any type of conveyor. Easy installation requiring no special toolse Direct contact on weighing load cell(s) avoiding maladjustments Local processing and issuing of a digital weight signal which is not altered by temperature Automatic device to control and correct the zero Automatic tarring and calibration software The SRT belt scale is approved by the French National Measurement Institute for Trade weighing Weighing accuracy is better than ±0,5 %
