S250 Miniature Platform Load Cell - Strain Gauge Sensors and Load Cells Manufactured for Custom and Standard Devices from SMD

Miniature Platform Load Cell - S251

The S251 Miniature Platform Load Cell is a low profile, single point OEM load cell offering high accuracy. Only 3/4" high, the S251 is ideal for medical instruments, low profile scales and other low profile, high resolution applications.

A 3,000 ohm thin film strain gauge bridge provides extremely low power consumption for battery and current loop applications. Capacities range from 200g to 10kg-force full scale (0.4 to 22 lb-force).
