calculate code width

Solved!

Stupid question but I can't find it through various searches.

 

How do I calculate code width and relate that back to engineering units on my sensor.

 

If I have a 24 bit ADC with a 500mV range I get 2.98 E-5 mV steps.  How do I convert that to engineering units.

Solved stupid question.

 

got gain factor for sensor i.e. (in units of V/engineering unit)

 

Then just multiplied that by my calculated voltage code input.

 

to get Engineering unit/DAQ bit

 

EU=(DAQVoltage range )/(bits)*(Sensor Gain)
