Straight Bar Load Cell Force Direction


I have an application where I need to measure the push and pull force required from a cable using straight bar load cell (e.g., Micro Load Cell [sku:RB-Phi-120]).

I was wondering if the load cell can read forces accurately in both directions (same orientation), or if there is any limitation due to the calibration of the component, or the strain gauges used in the wheatstone bridge being tuned specifically for compression/tension respectively.

Hi @nick02 !

Load cells are designed to measure force in one direction. They will often measure force in other directions, but the sensor sensitivity will be different, since parts of the load cell operating under compression are now in tension, and vice versa.

This sensor will measure only in the direction marked with a green arrow:
