ALF218 Cylindrical Force Sensor
Compact and robust force sensor for compression force measurements up to 400 kN. Ideal for dynamic and high-impact industrial applications.
Key features
- Compression force ranges up to 400 kN
- Rugged sealed design with IP65 protection
- High stiffness: up to 6.8 x 10⁹ N/m
- Low non-linearity: ±0.5% RL
- High repeatability: ±0.02% RL
- Output options: 2.3 mV/V or rationalised 2.0 mV/V
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
