Weighing plays a crucial role in cost control and safety across various business operations, from monitoring product deliveries to avoiding overloading penalties.

Often situated in remote or challenging environments, weighing systems must be implemented with minimal disruption to regular traffic flow. Freight may need to be weighed at high speeds, as many customers utilize a wide range of locomotives and rolling stock.

Essae Digitronics, one of the country’s leading weigh scale manufacturers, boasts the largest number of operational in-motion Weighing Systems nationwide, offering solutions to address the challenges associated with weigh-in-motion concerns.

Models with features

Rail Weigh in Motion (Rail-WIM)

Our Rail Weigh in Motion system is RDSO approved and a tailor-made train weighing solution that is easy to install at a low cost. Our team of experts develops and provides solutions for all rail users, from raw material procurement to end-users. Our microprocessor-based modular electronics, combined with high-quality strain gauges from the USA, ensure high accuracy even at varying speeds. The system can be designed for static and/or in-motion weighing of wheels, axles, bogies, and full draft weighing of locomotives and all types of rolling stock.

Rail-WIM provides precise data on rack and wagon weights, which can be seamlessly integrated with the client’s business systems through PCs, Ethernet, or the Internet.

By automatically detecting wheel, axle, and wagon overloads, this system helps identify imbalanced loads and prevents multiple weighments of the same vehicle, ensuring safety and avoiding overloading penalties.

RlMsoft: A Comprehensive and Smart Solution

Essae provides its proprietary software, ‘R|Msoft,’ which assists in obtaining weigh details in the desired format. It generates, stores, and prints reports of weigh data.

These reports can be linked to individual wagons, loads, and destinations, enabling you to monitor deliveries to and from customers and suppliers effectively.

Additionally, each machine comes with calibration software, allowing users to calibrate the weighbridge for different weather conditions, ensuring accurate weighing every time.
