2. Core Features and Advantages

Pressductor® Technology
Employs ABB’s patented pressure-magnetic measurement principle, in which the magnetic permeability of a ferromagnetic core varies with applied stress, eliminating the need for traditional strain gauges. This design ensures:

High mechanical strength and fatigue resistance

Outstanding shock and vibration durability

Suitability for long-term, high-frequency stress environments, such as rolling force detection in rolling mills

Exceptional Anti-Interference Performance
The sensor’s high-output signal and low impedance minimize sensitivity to electromagnetic interference (EMI) and insulation degradation. It maintains stable measurement accuracy even when insulation resistance drops to 10 kΩ, making it ideal for harsh industrial environments.

Installation Compatibility and Reliability

Standardized circular form factor allows direct replacement of sensors of similar dimensions

During installation, ensure that applied forces act perpendicular to the sensor axis

Avoid bending, lateral, or torsional forces that may affect accuracy

Typically installed with thrust bearings and positioning components for improved stress alignment and stability

3. Typical Application Scenarios

Rolling Mill Light-Load Measurement

Ideal for small and medium-sized rolling mills (e.g., cold-rolled strip steel, non-ferrous metal rolling)

Enables real-time rolling force feedback for precise thickness and shape control

Material Tension Control

Used in tension roller systems in papermaking, film, and foil production lines

Provides accurate coil tension measurement for maintaining constant tension control

Pressure Monitoring in Forming Equipment

Suitable for small and medium-sized presses

Detects and limits overload conditions to prevent die or mold damage
