Rail Weighing Systems

Our DS-405 and DS-505 are the simplest and accurate in-motion weighing systems. Our rail in motion weighing systems are based on modular design with high speed AID & ARM Controllers allows easy implementation of complete track logic sequence to deduct all type of wagons and locomotives automatically. Our system is also available with pit or pit less designs with the flexibility to interface with loading and other control systems. It also comes with a robust anti roll back up to 65000 axles. The i-rail fixon sensor is the most reliable and rugged rail sensor specially instrumented to weigh wagons weight axle by axle. Sensors can be used in combination for Full draft and two draft weighment to improve the accuracy. Hermitically sealed with improved mV/V is added advantage. Some of the salient features of our range comprises of the following:

• Our systems can be installed quickly within 3 hours by replacing the existing rails. These can also customize as per the client requirement
• Information stored can be retrieved even after 10 years
• Improved rail sensors such as SILO & Rapid loading system
• DS-405 / 505 are being designed with an interface for SILO/RLS loading systems
• RDSO approved
• The Silo loading can be with Tare and gross weighbridge on either side or full bridge below neath of the Bunker

Features:

• Fix on embedded - rail mounted sensor with hermetically sealed
• Pit / Pitless design option under single roof
• High speed and High accuracy
• Automatic correction of gain & zero
• Automatic Identification of Wagon and Engine
• Automatic Direction selection
• Auto Roll back up to 65000 wheels
• Direct print out of Rake information
• Approved under CLASS 0.2 As per OIML/LM
• Advanced over speed indicator
• Modular design for Silo and RLS loading
• High mv/v output with reduced SNR
• Inbuilt surge and lightning arrester
• Well built and maintenance free
• Weather proof design

Scope

The scope of supply covers Design, Engineering, Manufacturing, Supply, and erection, stamping by the Weights and Measures Department and commissioning of one number, Rail in Motion Weigh Bridges of Pit less Design.

Standards

The components of the Weigh Bridges will be designed, manufactured, assembled and tested as per relevant BIS and RDSO.

Sensing

Sensing will be through tracking Switches. The track Switches will be rugged and weatherproof. They will be of non contact type of proximity sensors and will perform the following functions.

(a). Non contact type Track Switches will be provided  to sense approach of the train from either direction, for speed measurement, to discriminate type of axle combination, to define weighing zone, to  “ start & stop “ Weighing cycle “

Junction Box

Junction Boxes will be weather proof.

Digitizer

Each Weigh Bridge will have independent Digitizers for processing the signal generated by the strain gauges and that by track switch logic. The DS 505 Digitizer will be housed in a sheet metal fabricated panel suitably reinforced. The panel will be of floor mounting type and will be of dust and vermin proof and will conform to IP: 55 protection class .A block diagram of the processor is enclosed.

The Digitizer will have microprocessor based circuitry with solid state integrated circuits to effect fast and reliable operation.. The Digitizer is constructed to the highest international standards, embodies the latest techniques and utilizes the best components to ensure highest possible reliability and integrity, even when used in harsh industrial environment. .The system can operate over a wide temperature range without affecting the accuracy and reliability the multiprocessor technology of the system allows independent processing of weight, rack logic and communication ensuring fast and accurate weighment. The system automatically monitor movement of wagon to initiate weigh cycle .Wagon movement on the Weigh Bridge is identified by Track Switch ,placed on either side of the track switch to detect direction , type of wagon , start and stop weighment.     

Power Supply to the Digitizer will be 230V, (+) / (-) 10 %, 50 Hz, Single phase AC. A Voltage stabilizer / Line Conditioner will also be provided. The other features, facilities are detailed below.  

(1). Modular construction
(2). Analog digital converter with filter                                                                                     
(3). RFI /EMI signal protection to provide high level of signal integrity even in harsh
       Industrial environment.
(4). Automatic zero maintenance.
(5). Diagnostic facility
(6). Auto calibration
(7). Built in surge arrester for protection electronic circuits
(8). 25 mm digital display and real time clock to display date and time
(9). RS 232 interfaces and Centronics parallel interface to the printer
(10). RS 422 serial port
(11). Option for operation of Weighing System with the help of Digitizer without the help of PC (in case of failure of PC)
