How to know the force (Newton), given a millivolt output?

Any Principles or Conversions?

 

Example:

30 mV = _______ Newton?

 

Pls Help

Impossible to answer unless we know the output characteristic of your load cell / amplifier...

so you mean it depends on the specification of that load cell like its load capacity and  output signal.....

 

Correct me if I'm wrong....plss

 

So if ive got a load cell that has:

max load capacity = 1250 kN

max output signal = 100 mV

 

so if ive got a measured output of 30 mV, then i will get a 375 kN force applied>?

 

 

30 mV * (1250 kN / 100 mV) = 375 kN..........

 

Plss confirm if im correct

 

thanks

Your computation seems correct.

 

Is this a strain gauge load cell ? Has it an integrated electronic or do you use an external amplifier ?

With this type of load cells, the output rate is expressed in mV/V and the output depends on the sensor's supply voltage.

 

Could you provide the datasheet in order to remove any doubt ?

Well this can be done actually. When you draw a graph of potential diffence, milivolt with respect to force, newton, you will find that 1 milivolt is equal to 100 newton.

I'd recommend starting a new topic and add a lot more detail to describe your problem.
