Description

ABB PFTL101A-2.0kN 3BSE004172R1

ABB PFTL101A-2.0kN (Order No.: 3BSE004172R1) is a medium-range high-precision tension/load cell under ABB's Pressductor® magnetoelastic technology platform, belonging to the Pillow Block load cell series. Specifically designed for the accurate measurement of tension, pressure and weight within the 2.0kN range in industrial scenarios, it is the core basic model of ABB's medium-load tension measurement product line. Relying on the unique advantages of magnetoelastic technology, this sensor can operate stably in various harsh industrial environments and is widely used in medium-load tension control and precision weighing scenarios.

1. Working Principle and Structural Features

This sensor achieves precise force measurement based on the magnetoelastic effect (also known as piezomagnetic effect): when mechanical force acts on the measuring assembly, the magnetic permeability of the internal material changes regularly. A dedicated detection circuit converts this change in magnetic permeability into a stable and accurate electrical signal, and finally completes the force measurement. Compared with traditional strain gauge sensors, its non-contact and wear-free measurement method fundamentally solves the problems of strain gauges being prone to fatigue and short service life, and also has stronger anti-interference ability and long-term operation stability.

Structurally, it adopts a practical and compact design, mainly composed of a measuring assembly (FR), a force conversion assembly (FV) and a 316L stainless steel housing. The housing is hermetically sealed by laser welding, with an IP67 protection rating, which can effectively resist the impact of harsh environmental factors such as dust, humidity, corrosive gas and strong vibration, and is suitable for various severe industrial scenarios. As a horizontal-measurement pillow block sensor, it supports both horizontal and inclined installation methods, which is easy to install and highly adaptable, and can be flexibly integrated into various industrial equipment and production lines.
