2. Core Features and Technological Advantages

Pressductor® Piezomagnetic Technology
Utilizes ABB’s patented piezomagnetic measurement principle, where the magnetic permeability of ferromagnetic material changes proportionally to applied stress.
This non-contact electromagnetic approach eliminates traditional strain gauges and ensures:

Exceptional impact and fatigue resistance

High overload tolerance for long-term, heavy-duty operation

Superior service life compared with conventional strain-gauge-based sensors

Ideal for continuous high-frequency load cycles such as rolling force detection in hot or cold rolling mills

Industrial-Grade Reliability

Insensitive to electromagnetic interference (EMI), vibration, and temperature fluctuation

Maintains stable operation even with insulation resistance as low as 10 kΩ

Designed for harsh industrial environments, including metallurgy, forging, and heavy machinery applications

Installation Adaptability

Circular structural design enables direct mounting at primary force transmission points (e.g., rolling mill stands, press beds)

Compatible with positioning pins and thrust bearing components to ensure precise vertical force transmission

Minimizes influence of lateral, bending, or torsional forces on measurement accuracy

3. Typical Application Scenarios

Heavy-Duty Rolling Mills

Used for rolling force detection in wide and thick plate mills and hot continuous rolling mills

Provides real-time force feedback to the control system

Core measuring element of Automatic Gauge Control (AGC) systems for plate thickness regulation

Large-Scale Hydraulic Presses

Monitors pressing force in 10,000-ton hydraulic and forging presses

Prevents equipment damage or workpiece scrap caused by overload conditions

Port and Heavy Machinery Applications

Integrated into container cranes and large lifting equipment for load monitoring and overload protection

Works in conjunction with safety interlock systems to ensure operational security and compliance with load regulations
