CL-YB-51-2

CL-YB-51-2 Rail-Pad Weighing Sensor

Digital rail-pad sensor for pit-free continuous-rail weighing. 30 t capacity, D0.5 accuracy class, RS485 output, IP67.

Product Overview

The CL-YB-51-2 rail pad type weighing sensor is a product specially developed for the Ministry of Railways, possessing multiple independent intellectual property rights and protected by national patents. It is designed for pit-free and rail-unbroken track weighing systems (rail weighers, overload and unbalance load detection) for various light rails, heavy rails, and crane rails. This sensor features high natural linearity, excellent impact resistance, and long-term stability. Its core indicators, such as service life and application reliability, are significantly better than similar foreign products. Relevant scientific research institutes under the Ministry of Railways have fully adopted this series of sensors to replace similar imported products since 2004. Since the 1990s, this sensor has been applied in the Railway Science Research Institute, as well as in the track weighing and lifting equipment weighing systems of large and medium-sized enterprises in the iron and steel, metallurgy, coking, mining, and other industries, such as Baosteel, Ansteel, Benxi Steel, and Taigang. It provides mature solutions for domestic customers of pit-free and rail-unbroken (including special crane rail) track weighing systems and weighing instrument manufacturers, pioneering the development of pit-free and rail-unbroken track weighing devices for crane rails.

Product Advantages

  • Leading Patent Technology: With multiple independent intellectual property rights and protected by national patents, its technical level has reached the international advanced level. Its service life and reliability are better than similar foreign products, and it has fully replaced imported products.

  • Flexible Structure: It provides multiple structural designs such as ultra-thin type (Series A) and ultra-narrow type (Series B), which adapt to different installation scenarios. With a multi-support force-bearing design, the output signal is proportional to the external force, and the number of sensors can be flexibly increased or decreased to meet different weighing requirements.

  • Excellent Performance: It has high natural linearity, excellent impact resistance, and long-term stability, and can realize dynamic and static rapid weighing as well as overload and unbalance load detection.

  • Convenient Installation: Specially designed for pit-free continuous rail track weighing systems, it does not require modification of the original track structure and is compatible with various rail types such as light rail, heavy rail, and crane rails.

  • Industry Recognized: Since the 1990s, it has been successfully applied in the Institute of Railway Sciences and many large domestic enterprises, and has been widely recognized by weighing instrument experts, designers, and the majority of users.

  • Wide Adaptability: It has a series of products applicable to U38, U43, U50, U60, U65, U75, QU80, QU85, QU100, and QU120 rails, and is compatible with all types of rails.

Applicable Scenarios
It is widely used in high-speed railway freight transportation lines, realizing dynamic (static) rapid weighing and rapid overload and unbalance load detection for pit-free continuous rails. Since the 1990s, it has been applied in the Institute of Railway Sciences, as well as in the track weighing and lifting equipment weighing systems of large and medium-sized enterprises in steel, metallurgy, coking, mining, and other industries, such as Baosteel, Ansteel, Benxi Steel, and Taigang.
