MD Series Running Line
The MD Series is a specialized Running Line Load Cell engineered to measure tension in ropes, wires, or cables as they move through a system.
It is commonly used in industries such as marine, construction, oil and gas, and other applications where monitoring tension in a line is critical for safety and performance.
Key Features of a Running Line Load Cell:
- Dynamic Tension Measurement: It measures the force exerted on the line as it moves, providing real-time data.
- Non-Invasive Design: These load cells often do not require cutting or modifying the line. They are mounted so the line passes through or over the device.
- Rope and Line Compatibility: They are designed to accommodate a variety of line diameters and materials, such as wire ropes, synthetic ropes, or cables.
- Durability: Often made from materials like stainless steel or other robust alloys to withstand harsh environments, especially in marine or offshore applications.
- Sensor Integration: Many include strain gauges or other sensors to measure tension accurately.
Output Options: These devices typically provide digital or analog signals for integration with monitoring systems, such as PLCs, computers, or wireless systems.

Working Principle:
The running line load cell operates by applying mechanical force from the moving line to a load-sensing mechanism. As the line passes over rollers or pulleys integrated into the load cell, the tension in the line is translated into a measurable signal. This data is then processed and displayed or transmitted to a control system.

- Winching Operations: To monitor and control tension in winch lines.
- Mooring Systems: For tracking tension in mooring ropes.
- Lifting and Rigging: Ensuring safe tension levels during hoisting.
- Towing: Monitoring line tension in towing operations.
- Cable Laying: Measuring tension in cables during installation.
- Load Limitation: Load limitation and measurement in load handling devices, cranes, winches, and overhead cranes (in combination with external controllers such as Krukload 500 and Torium5-510MD).
Advantages:
- Provides continuous tension monitoring without halting operations.
- Prevents overloading and potential line failures.
- Enhances operational safety and efficiency.
