Compact miniature force sensor for precise force measurement

The ALF250 miniature force sensor is designed for highly accurate force measurements where installation space is limited. With a diameter of just 15 mm, this compact diaphragm-based force sensor delivers reliable performance in both tension and compression applications.

Its small size, robust stainless steel construction and excellent repeatability make it an ideal solution for OEM equipment, industrial automation, scientific research and laboratory testing. Available in compression, tension and bidirectional versions, the ALF250 offers maximum flexibility for demanding measurement applications.

Performance highlights

The ALF250 is available with measuring ranges of 100 N, 200 N, 400 N and 800 N. Every sensor is supplied with a traceable calibration certificate as standard, ensuring reliable and repeatable measurement performance.

Manufactured from hardened stainless steel and protected to IP65, the sensor is suitable for continuous operation in industrial environments while maintaining stable measurement accuracy.

Usage conditions

The force should be applied directly through the central loading axis to ensure optimum accuracy. The ALF250 is available as a standard load button version for compression applications or as a stud version for tension, compression or bidirectional measurements.

The sensor operates between -10°C and +80°C and is supplied with a 2 m screened cable for easy installation.

Possible applications

  • OEM machine integration
  • Industrial automation
  • Laboratory testing
  • Scientific research
  • Material testing
  • Force control systems
  • Medical devices
  • Robotics
  • Assembly equipment
  • Precision engineering
