2. Core Technologies and Advantages

Pressductor® Magnetic Pressure Technology
Employing ABB’s patented magnetic pressure (piezomagnetic) principle, the sensor measures applied force through changes in magnetic permeability of a ferromagnetic core under stress.
Because no strain gauges or fragile elements are used, the sensor offers:

Outstanding impact and fatigue resistance

Capability for continuous, high-frequency, heavy-load operation (24-hour duty in roughing and finishing mills)

Exceptional service life—typically 15 years or longer under normal industrial conditions

No recalibration drift and minimal maintenance requirements

Industrial-Grade Anti-Interference Capability

High-power output signal ensures stable operation even in strong electromagnetic fields

Unaffected by EMI, poor grounding, or insulation degradation (stable performance with insulation resistance ≥ 10 kΩ)

Proven in metallurgy, forging, port machinery, and large mechanical systems requiring precision under severe interference

Installation Adaptability

Standardized circular structure enables direct replacement of sensors of similar series (e.g., 40 MN / 50 MN models)

Requires thrust bearings and positioning components to ensure axial vertical force transmission

Lateral forces must be limited ≤ 5 % of rated load to maintain measurement accuracy

Uniform height (74 mm) allows seamless integration and modular interchangeability

3. Typical Application Scenarios

Extra-Large Rolling Mills

Real-time rolling-force monitoring in wide-plate, thick-plate, and hot-strip mills (including roughing stands)

Serves as the core feedback element in Automatic Gauge Control (AGC) systems to maintain thickness precision and product quality

Ultra-Large Forging Equipment

Measures and monitors forging or pressing forces in hydraulic presses above 10 000 tons

Prevents structural damage, tooling failure, and workpiece scrap caused by overload

Heavy Engineering and Structural Testing

Suitable for static / dynamic load monitoring in bridge bearings, dam gates, and port lifting structures (e.g., shore-based cranes)

Enables real-time evaluation of structural load-bearing capacity and safety margin assessment
