ABB PFTL301E 1.0kN 3BSE019050R100

ABB PFTL301E 1.0kN (Order No.: 3BSE019050R100) is a compact tension control load cell under ABB, belonging to the Pressductor® technology platform. Specifically designed for the accurate measurement of horizontal component force of web tension within the 1.0kN range in industrial scenarios, it is a core measurement device in the web processing industry. Adopting ABB's patented magnetoelastic (piezomagnetic) technology, this product combines high precision, high stability and compact design advantages, which can ignore the interference of tension roll weight, accurately capture tiny changes in tension, and is widely used in various industrial scenarios requiring precise tension control. It is also suitable for upgrading and replacing existing equipment with convenient installation and outstanding cost performance.

1. Working Principle and Structural Features

This sensor (tension control load cell) achieves precise measurement based on ABB's patented Pressductor® magnetoelastic technology (also known as piezomagnetic effect). Its core principle is: the sensor is equipped with four mutually perpendicular coil mounting holes, and two sets of mutually perpendicular coils are wound through these holes; in the no-load state, there is no magnetic coupling between the two sets of coils; when horizontal tension load is applied, the magnetic permeability of the internal steel changes regularly—the magnetic permeability decreases in the force direction and increases in the vertical direction, leading to changes in magnetic flux symmetry. The secondary coil generates an induced voltage proportional to the load, which is converted into a stable electrical signal after signal conditioning, and finally completes tension measurement. This non-contact, non-physical movement measurement method enables it to complete detection without deformation, with super strong overload tolerance and almost unlimited load cycle life, no drift, and no on-site recalibration, fundamentally reducing maintenance costs.

Structurally, it adopts a compact design with an overall size of 115mm×75mm×35mm and a weight of only 0.4kg. Its size is consistent with traditional load cells, and the installation method is fully compatible, facilitating the upgrading or replacement of existing equipment without modifying the equipment structure. The housing adopts a robust and durable protection design with an IP67 protection rating, which can effectively resist the impact of harsh environmental factors such as dust and humidity, and is suitable for dusty and high-humidity industrial scenarios. It integrates a signal conversion and isolation amplification module inside, which can convert analog signals into digital signals and perform isolation amplification, ensuring the accuracy and stability of signals, facilitating the reception and processing by PLC or other controllers. It also has a programmable input and output range to adapt to different application needs.
