Description
ABB PFTL101BE 2.0kN 3BSE004214R1
I. Overview
ABB PFTL101BE 2.0kN 3BSE004214R1 is a pillow-type sensor, positioned as a "precision horizontal force measurement unit for low-tension and high-speed scenarios". Based on the patented Pressductor® magnetoelastic technology, this sensor achieves measurement by leveraging the principle that the magnetic properties of stainless steel change under mechanical stress. Specifically designed for low-tension horizontal force monitoring, it can accurately capture tension variations during the processing of materials such as textiles, paper, and thin metal strips, and stably output data even under heavy roll load and high operating speed conditions.
II. Core Features
Patented Magnetoelastic Technology & Ultra-high Precision: Based on Pressductor® magnetoelastic effect technology, it achieves non-contact measurement without the need for strain gauges, converting force values by detecting changes in magnetic permeability. With a nonlinear error ≤±0.02%FS, repeatability ≤±0.01%FS, and creep error of only ±0.02%FS/30min, it responds sensitively to tiny tension changes with a resolution of 0.01N, meeting the precise monitoring requirements of low-tension scenarios.
Corrosion-resistant Structure & Adaptability to Harsh Working Conditions: Integrally formed from 316L stainless steel with a laser-welded sealing process, it has an IP67 protection rating, providing dustproof, short-term water immersion, and acid corrosion resistance capabilities. It is specially designed for multi-corrosive medium scenarios such as the wet end of paper machines; compliant with the IEC 60068-2-6 vibration resistance standard, it can operate stably for a long time under high-speed and heavy roll load conditions without wear and tear, ensuring a long service life.
Wide Temperature Adaptability & Stable Output: Operating within a temperature range of -40℃ to 80℃, it has a low temperature coefficient of ±0.005%FS/℃. The built-in temperature compensation circuit realizes full-temperature range precision calibration, avoiding measurement deviations caused by temperature changes. The output signal can be selected as native mV/V signal or standard 4-20mA analog signal, with strong anti-electromagnetic interference capability, suitable for complex industrial electromagnetic environments.
Convenient Integration & Mounting Adaptability: Adopting a fixed cable connection design, it avoids the risk of loose plug-in interfaces and is compatible with 6-core shielded cable transmission; supporting flange mounting or embedded mounting, it features a compact structure (dimensions: 263mm×138mm×88mm, net weight: approx. 2.35kg), which can flexibly adapt to the narrow installation space of equipment and be put into use without complex debugging.
- Exclusive Optimization for Low-tension Scenarios: Specifically optimized for low-tension, high-speed, and heavy roll load scenarios, it has a response time of <100ms, enabling rapid capture of dynamic tension fluctuations without resonance or noise issues; with an overload capacity of 150% of the rated load (3.0kN) and strong lateral load resistance, it can withstand sudden load impacts and ensure equipment safety.

IV. Working Principle and Application Logic
The ABB PFTL101BE 2.0kN sensor achieves precise horizontal force measurement in low-tension scenarios based on the magnetoelastic effect, following the core logic of "stress sensing - magnetic change conversion - signal conditioning - data output". Its core working process is as follows:
The sensor is installed at the force-bearing point of the equipment (such as the roller pillow block of a paper machine) via flange or embedded mounting. When low-tension horizontal force acts on the sensor, the internal 316L stainless steel inductor undergoes linear changes in magnetic permeability due to mechanical stress, completing the conversion of mechanical force into magnetic signals without physical deformation, thus avoiding wear and tear.
The built-in detection coil captures changes in magnetic permeability and converts them into weak mV/V electrical signals, which are amplified and filtered by the signal conditioning circuit to optimize signal quality; meanwhile, the temperature compensation circuit offsets the impact of ambient temperature changes, and the low-impedance AC signal characteristics resist electromagnetic interference and ground faults, ensuring signal stability.
The processed signal is transmitted via a fixed shielded cable. The native mV/V signal can be directly connected to a dedicated controller, and the optional 4-20mA conversion module is compatible with PLC and DCS systems, providing accurate data support for tension adjustment mechanisms, realizing closed-loop control in low-tension scenarios, and ensuring uniform material tension.
