ALS251 Miniature Platform Load Cell

Load Cell ALS251

The ALS251 Miniature Platform Load Cell is a low profile, single point OEM load cell offering high accuracy. Only 0.71" (18 mm) high, the ALS251 is ideal for medical instruments, low profile scales and other low profile, high resolution applications.

A 3000 ohm thin film strain gauge bridge provides extremely low power consumption for battery and current loop applications. Capacities range from 200 g to 10 kg-force full scale (approx. 2 N to 100 N).

Safety Note

When using the load cell in tension mode it is essential to provide additional safety precautions like safety chains etc. for catching the load in a breakage, which cannot be excluded completely.
