A rail scale is also called "railroad scale" or "train scales". Rail scales are widely used by many railway operators, mining companies and rail vehicle maintenance workshops.
A rail scale is installed in the track and weighs a train when a train passes over. The train scales weighing results are then stored locally or transferred to remote locations and new technologies are used for data sampling, analog-digital conversion, and data transmission. With the advanced and well designed weighing electronics, train scales can be used to measure the weight of trains travelling up to 85kmh, and the weight data can be transferred to anywhere in the world, by phone line, internet etc.
There are two types of train scale systems: Strain Gauge Systems and Loadcell Weighing Systems. Loadcell weighing systems have been proven to be the most accurate and reliable train and truck weighing systems for more than 30 years. Many strain gauge systems are now being replaced by loadcell based train weighing systems, as in the past users found these type of systems to be unreliable and having constant temperature problems, and also high installation and maintenance costs along with lengthy installation and repair down time. |
