View technical specifications

Key features

  • Measurement ranges from 30 N to 300 N
  • Tension and compression measurement
  • Integral misalignment error compensation
  • Optional overload protection
  • High accuracy with traceable calibration
  • Weather-sealed IP65 version available

Performance highlights

The ALF241 is a high-accuracy axial compensated force sensor, delivering precision measurements in both tension and compression modes. It features a nominal output of 2.2 mV/V and an optional rationalised output of 2.0 mV/V ±0.1 %. With a non-linearity of just 0.05 % RL, and low hysteresis and creep values, the ALF241 ensures stable and reliable force readings in demanding conditions.

Usage conditions

  • Operating temperature range: -10 °C to +80 °C
  • Compensated temperature range: -10 °C to +50 °C
  • Safe overload up to 120 %, ultimate overload up to 200 % RL
  • Dynamic loading capacity: up to 70 % RL
  • Constructed in aluminium with multiple mounting options
  • Available with a 2 m screened PVC cable

Possible applications

  • Process weighing systems
  • Low-range force testing benches
  • Precision mechanical assemblies
  • OEM machinery
  • Engineering test setups
  • Automation and robotics

Advantages of choosing this product

The ALF241 excels in environments where compact design, high repeatability, and ease of integration are essential. Its flexure strain geometry and axial compensation provide excellent resilience to off-axis loading errors. Optional features such as overload protection and rationalised output improve safety and ease of system integration.

Other important features

  • Rated loads: 30 N, 50 N, 100 N, 300 N
  • High repeatability: ±0.02 % RL
  • Stiffness up to 1.5 x 10⁶ N/m
  • Bridge resistance: 350 Ω
  • Multiple configurations: compression (button or thread), tension, bi-directional
