Description
ABB PFTL101B-2.0kN 3BSE004185R1
The ABB PFTL101B-2.0kN (Order No.: 3BSE004185R1) is a medium-range high-precision tension/load cell, specifically designed for the accurate measurement of tension, pressure and weight within the 2.0kN range in industrial scenarios. As a core upgraded model in ABB's tension measurement product line, it is widely used in tension control and load metering applications across various harsh industrial environments by virtue of the unique advantages of magnetoelastic technology.
I. Working Principle and Structural Features
This sensor operates based on the magnetoelastic effect (also known as the piezomagnetic effect). Its core principle is that when mechanical force acts on the sensor's 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, thereby achieving precise force measurement.
Compared with traditional strain gauge sensors, its non-contact and wear-free measurement method fundamentally solves the pain points of strain gauge sensors such as easy fatigue loss and short service life, while offering stronger anti-interference capability and long-term stability.
The sensor features a reinforced structural design as a whole, mainly consisting of three parts: a measuring assembly (FR), a force conversion assembly (FV) and a 316L stainless steel housing. The housing is hermetically sealed via laser welding, reaching an IP67 protection rating, which can effectively resist the impact of harsh environmental factors such as dust, humidity and corrosive gas, making it suitable for various severe industrial scenarios. With a compact structural design, it is a horizontal-measurement pillow block load cell that supports both horizontal and inclined installation methods. It is easy to install and highly adaptable, and can be flexibly integrated into various industrial equipment and production lines.
