ABB PFTL101A 0.5KN 3BSE004160R1
1. Product Overview
The PFTL101A is a magnetoelastic tension (force) sensor belonging to the ABB Pressductor series, with a rated measurement range of 0.5 kN (approximately 50 kgf). It realizes force-to-electricity conversion based on the magnetoelastic effect. Widely applied in industrial sites both at home and abroad, this model can provide analog (4‑20 mA) or digital (HART, PROFIBUS PA, FOUNDATION Fieldbus) outputs, making it compatible with various automation systems.
