ALF238 Bending beam load cell
Compact single point load cell for precise force measurement in tension and compression. Designed for OEM integration where space, accuracy and reliability are critical.
Key features
- Measurement range 50 N to 300 N
- Non-linearity ±0.05 % RL
- Tension and compression calibration
- 2.0 mV/V rationalised output
- Compact aluminium construction
Performance highlights
The ALF238 bending beam load cell is engineered for accurate force measurement in low-capacity applications. With rated loads of 50 N, 100 N and 300 N, it delivers high precision thanks to a non-linearity of ±0.05 % RL and repeatability of ±0.02 % RL.
The binocular bending beam design provides excellent moment immunity, minimizing measurement errors caused by off-centre loading.
Usage conditions
The sensor operates within a compensated temperature range of -10 °C to +50 °C and withstands operating temperatures up to +80 °C. With a 350 Ω bridge resistance and 10 V supply voltage, it integrates easily into standard strain gauge measurement systems.
Safe overload capacity is 120 % RL and ultimate overload reaches 200 % RL.
Possible applications
- Laboratory force testing
- Small-scale material testing
- OEM machinery integration
- Quality control systems
- Tension monitoring applications
Advantages of choosing this product
The compact aluminium design ensures easy installation in limited spaces. The load cell is available in compression, tension or bi-directional calibration versions, including rationalised output options for simplified signal conditioning.
Traceable calibration with certificate guarantees reliable and repeatable results.
Other important features
