ABB Type Designation:

PFSK 152 Repair

Catalog Description:

Signal concentrator board

The ABB PFSK152 (3BSE018877R1) is a sophisticated Signal Processing Unit within the ABB Pressductor® tension measurement family. While it shares a lineage with the PFSK151.

the 152 model is often utilized for more complex configurations requiring enhanced signal handling and communication within the Advant Controller 400 and MasterPiece environments.

Introduction

The PFSK152 acts as the high-speed interface between physical load cells (transducers) and the industrial control system.

It is engineered to excite the transducers and process the resulting millivolt signals into accurate, real-time tension data.

It is widely recognized for its "industrial-grade" stability, capable of maintaining accuracy despite extreme temperature fluctuations and electromagnetic interference.

Technical Parameter Table

Product Advantages and Features

Multi-Channel Flexibility: Capable of processing signals from two independent load cells or calculating total/differential tension.

High-Frequency Response: Fast signal updates make it ideal for high-speed tension control loops in metal and paper production.

Self-Monitoring Intelligence: Features internal watchdogs that detect sensor failure, cable breaks, or excitation errors instantly.

Legacy Reliability: Designed for 24/7 operation in "dirty" electrical environments without signal drift.

Application Cases

Hot Rolling Mills: Measuring the tension of steel strips between mill stands to prevent necking or breakage.

High-Speed Slitters: Controlling the winding tension of plastic films where even minor fluctuations can cause material deformation.

Coating Lines: Maintaining constant tension through chemical baths and drying ovens in the manufacturing of specialty membranes.

Marine & Cable Laying: Monitoring the tension of underwater cables during deployment.

Unique Product Description

The PFSK152 (3BSE018877R1) is the "heavy-lifter" of the ABB tension world. Unlike standard converters that use strain gauges, this unit is optimized for Magnetoelastic measurement.

It creates a magnetic field within the sensor and measures the change in that field caused by mechanical stress.

This makes the PFSK152/Load Cell combination virtually indestructible compared to fragile foil-based sensors, as it has no moving parts or microscopic wires to break.

Installation and Maintenance

Installation

Environment: Install in a clean, dry cabinet (IP54 recommended for the outer enclosure).

Bus Connection: Ensure the ribbon cable/bus connector is firmly seated to prevent communication timeouts with the AC450 controller.

Shielding: The transducer cable shield must be grounded at the processing unit end only to avoid ground loops.

Maintenance

Zero-Set: Periodically perform a "Tare" or Zero-set when the machine is empty to account for roll wear or mechanical shifts.

Voltage Checks: Verify the +24V supply stability; fluctuations in input power can lead to "noisy" tension readings.

Replacement: The unit is modular; if a fault is detected via the onboard LEDs, the entire board can be hot-swapped (depending on the backplane configuration).
