I. Product Description
ABB PFS140 RULLM 9K 3BSE00653R1 Pressductor is a dedicated roll-type sensor excitation power supply unit for tension measurement control systems, compatible with PFCL and PFTL series magnetically-actuated tension sensors. It provides high-precision and stable AC excitation power for the 9kN range tension measurement circuit, pre-processes the weak tension sensing signal from the sensor, and transmits it to the PFEA series tension amplifier to achieve precise tension collection and closed-loop control for steel belts, paper, films, etc. in the roll material production lines. It is mainly used in papermaking, metallurgical cold rolling production lines for tension control systems as spare parts.

Product Performance
High-precision constant current excitation output, voltage fluctuations and line voltage drop will not change the excitation parameters, ensuring the long-term linear stability of tension sensors during measurement and eliminating zero drift
Built-in dual-channel independent excitation circuits, can simultaneously power two symmetrical installed pillow-type tension sensors, supports tension summation and deviation calculation
Integrated multiple hardware protections for line short-circuit, sensor break, and excitation overcurrent, instantly cuts off excitation and gives local alarm to avoid burning of sensors and front-end amplifiers
Multiple levels of hardware filtering for output signals, can suppress industrial electromagnetic interference from frequency converters and high-power motors, suitable for strong interference working conditions of rolling machines and high-speed paper machines
Perfectly compatible with ABB's entire series of PFEA111/PFEA112/PFEA113 tension amplifiers, standardized system wiring, convenient on-site debugging and replacement
Wide temperature industrial hardware design, supports 7×24 continuous uninterrupted operation, suitable for humid, dusty harsh production environments
