2. Core Technologies and Advantages

Pressductor® Magnetic Pressure Principle
Based on ABB’s patented magnetic permeability variation technology, this transducer measures force through changes in the magnetic properties of ferromagnetic materials under stress.
Unlike conventional strain gauge sensors, it contains no bonded elements or vulnerable components, offering:

Exceptional impact and fatigue resistance

Capability for continuous high-frequency heavy load operation (e.g., 24-hour rolling applications)

Long service life exceeding 10 years under normal industrial operating conditions

Stable, drift-free performance with minimal maintenance requirements

Robust Anti-Interference Design

High signal power output ensures stable readings even in strong EMI environments

Insensitive to poor grounding and insulation degradation (operational stability maintained with insulation resistance down to 10 kΩ)

Proven reliability in metallurgy, forging, and heavy machinery environments

Installation Compatibility

Standardized circular design allows direct replacement of existing ABB or compatible sensors of equivalent dimensions

Must be installed with thrust bearings and positioning components to ensure vertical load transfer

To preserve accuracy, lateral forces must be limited to ≤ 5% of rated load

Uniform sensor height (74 mm) simplifies integration across multiple system configurations

3. Typical Application Scenarios

Large-Scale Rolling Mills

Used for real-time rolling force measurement in wide and thick plate mills and hot continuous rolling lines

Serves as a core feedback component for Automatic Gauge Control (AGC) systems to ensure plate thickness precision and product uniformity

Heavy Forging Equipment

Monitors pressing or forging forces in 10,000-ton hydraulic presses and industrial forming machines

Prevents mold damage, equipment overload, and workpiece deformation during high-force operations

Bridge and Structural Testing

Applicable for monitoring static and dynamic load forces in bridge bearings and large civil structures

Supports structural strength evaluation and bearing capacity analysis in safety inspection systems
