ALF251 Miniature diaphragm loadcell
Compact and reliable loadcell for measuring tension and compression forces in tight installation spaces. Ideal for OEMs and dynamic testing setups.
Key features
- Compact design for tight spaces
- Measures tension, compression, or both
- IP65 sealed stainless steel or aluminum body
- High repeatability and low hysteresis
- Rationalised or unrationalised output versions
- Traceable calibration certificate included
Performance highlights
The ALF251 is a highly compact miniature diaphragm loadcell designed for bi-directional force measurements in compression and tension. With a nominal rated output of 1.6 mV/V and a non-linearity of ±0.5% RL, it offers accurate and repeatable results. Versions with rationalised outputs ensure interchangeability across installations.
Usage conditions
Suitable for environments with temperatures between -10°C and +80°C, the sensor is IP65-sealed, offering protection against dust and splashes. Safe and ultimate overload ratings of 50% and 100% of rated load respectively ensure durability under demanding conditions.
Possible applications
- OEM force measurement in automation systems
- Testing rigs and lab experiments
- Control systems in industrial processes
- Integration in mobile or static setups
- Monitoring systems in confined assemblies
Advantages of choosing this product
The ALF251 offers unparalleled flexibility in tight spaces, thanks to its miniature load button design. Its bidirectional calibration options, multiple ranges (from 100N to 3.2kN), and fast integration make it a preferred solution for test engineers and OEM developers alike.
Other important features
- Available in aluminum (up to 200N) or stainless steel
- Easy installation with standard threaded versions
- Custom designs available upon request
- 2-meter shielded cable included
- Rationalisation capsule integrated in cable for rationalised models
