Product Advantages and Features
Precision Filtering: Advanced digital filtering eliminates mechanical noise and vibrations, ensuring stable tension readings even at high speeds.
Built-in Diagnostics: Constantly monitors the health of the connected load cells and internal circuitry, reducing unplanned downtime.
Plug-and-Play Integration: Designed specifically for the Advant OCS and Master systems, allowing for seamless communication.
Robust Isolation: High galvanic isolation protects the processor from electrical surges and industrial interference.
Application Cases
Paper & Pulp Mills: Managing web tension in paper machines to prevent breaks and ensure consistent winding.
Steel Processing: Monitoring strip tension in rolling mills and galvanizing lines to maintain product thickness and quality.
Converting & Printing: Controlling tension for plastic films, foils, and high-speed printing presses.
Textile Industry: Ensuring uniform tension during fabric dyeing and finishing processes.
Unique Product Description
The PFSK151 stands out because of its heritage in Pressductor® technology. Unlike standard strain gauge processors, this unit is engineered to handle the high-output,
low-impedance signals characteristic of ABB’s heavy-duty transducers. It doesn’t just “read” data; it interprets the physical stress of industrial machinery with surgical precision,
making it the gold standard for harsh environments where reliability is non-negotiable.
Installation and Maintenance
Installation
Mounting: Secure the unit onto a standard 35mm DIN rail. Ensure at least 20mm of clearance for airflow.
Wiring: Use shielded twisted-pair cables for signal inputs to minimize EMI. Ensure the 24V DC power supply is stable.
Grounding: Connect the PE (Protective Earth) terminal directly to the common ground busbar.

Maintenance
Calibration: It is recommended to perform a zero-point calibration annually or after any mechanical changes to the load cell mounting.
Cleaning: Ensure the cooling vents remain free of dust and debris, especially in paper or textile environments.
Firmware: Periodically check for compatibility updates if upgrading the master controller system.
