Performance highlights

The ALF218 is a high-capacity compression force sensor designed for engineering-grade force measurement tasks. With a small cylindrical form factor and domed top load face, it offers a robust design capable of handling non-sacrificial impact forces. Rated loads range from 100 kN to 400 kN, with excellent repeatability and linearity.

Usage conditions

With a sealed IP65 housing and a temperature-compensated range of -10 to +50 °C, the ALF218 ensures stable operation in industrial environments. The safe overload limit is 150% of rated load, and the ultimate overload threshold is 400% of RL.

Possible applications:

• Impact force testing in automotive or material labs
• Compression monitoring in press-fit assembly lines
• Structural load testing in civil engineering
• OEM applications requiring high structural stiffness
