Rail Weighbridge - Load Cell-based In-motion Weighing System, High Speed With Digital Intelligent Detection

Rail Weighbridge

In-motion Weighing System overcomes many of the limitations inherent of conventional static weighing systems by being able to weigh wagons on the move. The state of art highly sophisticated yet simple in-motion weighing system has been designed and developed indigenous. With conventional systems, each wagon has to be uncoupled from those adjacent to it, and then carefully positioned and parked on the weighbridge before its weight can be recorded. Digital intelligent, innovative system is designed to detect the different type of wagons to initiate the axle or bogie weighing. Also it automatically detects the different type of engines and eliminates its Weighment. The speed of wagon is directly related to the accuracy of weighment. The high speed A/D Micro Controller are having a remarkable compatibility to achieve accurate weighment even up to a speed of 15KM/hr.

Track Requirements Bridge

The Micro-controller based menu driven Electronic Digital Weight Indicator designed for high performance industrial weighing applications. In this the user selects the operating functions appropriate to his application requirements. The weighing system offers the following features: For getting optimum accuracy, the following track conditions are recommended.

System Overview

The load cell based in-motion weighing system consisting of 4 load cells, weighbridge with prefabricated supporting structure and rail approaches. The load cells are strain gauge based sensors, which convert weight in to electrical signal with very high accuracy and stability. Wagon movement on the weighbridge is identified by Track Switches placed on either side of bridges, to detect the direction, type of wagon, start and stop weighment.

The approach Rails are rigidly tightened with approach beams to restrict the rail movement and smooth load transfer to the weighbridge. The misalignment of approach rails and weigh rail may induce errors in accuracy.
