ABB PFTL101A Horizontal Pillow-Type Tension Gauge Indenter

The ABB PFTL101A, also cataloged as the PFTL101A Horizontal Pillow-Type Tension Gauge Indenter, operates as a dedicated hardware component for web tension force measurement within industrial strip processing and rolling mill platforms.

Hardware Specifications

Industrial Control and Drive Architecture

• Backplane Bus Communication Velocity The raw load cell signals interlock with dedicated ABB Pressductor matching amplifiers, transmitting scaled analog force data directly to the controller processing bus. This direct signal processing loop limits latency, maintaining instantaneous load data velocity down to the millisecond scale during rapid line speed changes.
• Profinet / EtherNet/IP Deterministic Networks The digitized force outputs from the downstream interface card link into deterministic control networks. This division isolates high-frequency mechanical measurement updates from external plant network traffic, keeping strip tension feedback tight and synchronized within the motor drive loops.
• I/O Density Scaling and Mechanical Layout The pillow-type casing integrates mechanical measurement zones into single-chassis layouts beneath the roll bearings, reducing extra mounting hardware. This form factor tracks high-capacity force metrics over a broad tension range without disrupting baseline roll positioning configurations.
• Firmware Flash Compatibility and Calibration Accuracy Load units are factory-calibrated prior to delivery. The localized force sensitivity variables mesh with the linearization curves flashed into the processing amplifier firmware, providing constant measurement stability when tracking wide, heavy metal strips.

Frequently Asked Questions

Q: What structural difference distinguishes the mill-type PFTL101A variant from standard units in fluid-heavy processing environments?

A: The mill-type version uses a permanently molded, fixed connecting cable entry instead of a standard plug connector. This modification maintains an IP 66 ingress rating, preventing emulsions, processing oils, or rolling liquids from seeping past the terminal pin seals.

Q: How does the internal spring constant affect mechanical operation under maximum transverse overload?

A: The high spring constants (up to 130 kN/mm) provide a highly rigid structure with a maximum physical deflection of just 0.015 mm at rated load. This stiffness keeps the roll aligned during transverse load shocks (up to 10.0 kN), preventing strip tracking errors or bearing wear.
