Order number: 3BSE024994R5000
The suffix “R5000” specifies the 50.0 MN standard configuration — this is the official and unique order code for this model.

Core Technologies and Advantages

Pressductor® Magnetic Pressure Technology:
Based on ABB’s patented magnetic pressure effect, force measurement is achieved through the change in magnetic permeability of ferromagnetic materials under stress.
This design eliminates traditional strain gauges and other fragile components, providing exceptional impact resistance, fatigue strength, and long-term stability under continuous heavy loads (e.g., 24-hour rolling operations).
The expected service life exceeds 20 years, significantly outperforming conventional load sensors.

Extreme Environmental Adaptability:
High output signal power and immunity to electromagnetic interference (EMI), poor grounding, and insulation degradation (maintains stable operation even when insulation resistance drops to 10 kΩ).
Fully suitable for harsh industrial conditions such as metallurgy, heavy forging, and environments with high dust or electromagnetic noise.

Installation Compatibility:
Standardized circular structural design enables direct replacement of existing sensors of the same series and dimensions (e.g., 45 MN, 56 MN models).
Installation requires special thrust bearings and positioning pins to ensure that applied forces act vertically on the sensor axis.
Lateral forces must be limited to ≤ 5% of rated value to prevent measurement deviations and maintain long-term accuracy.

Typical Application Scenarios

Extra-Large Rolling Mills:
Provides real-time monitoring of rolling force in wide and thick plate roughing mills and hot rolling mills (support roll systems).
Serves as the core feedback element of the AGC (Automatic Gauge Control) system, ensuring plate thickness accuracy within ± 0.1 mm.

Ultra-Large Forging Equipment:
Measures forging force in hydraulic or water-pressure presses with capacities exceeding 15,000 tons.
Prevents overload-induced deformation of press frames or damage to molds, ensuring forming quality of large-scale forgings such as wind turbine spindles and nuclear power pressure vessels.

Heavy Engineering Structure Monitoring:
Used for static and dynamic force monitoring of bridge bearings, hydraulic gate actuators, and super-large port cranes (shore bridges).
Provides critical data for long-term structural load evaluation and safety assessment.
