Does anyone know if it is possible to use a Thermocouple/ mV
Analog Input Module 1746-NR4 to measure data from a load cell.
The 3 load cells that we are using are Paralleled together to give an output of 6 millivolts at max. Since the NR4 can measure up to 50mv,
I was wondering if it is all possible this way.
I will more than likely use an amplifier and then convert the signal to 0 to 10 volts.
Can anyone suggest a amplifier? Cleveland-Kidder makes one called a Ultra that mounts on a din-rail.
Also these load cells require a 10V input, can anyone recommend a 10V power supply. I think 12V power supply probably is to high.
FYI: The customer assured us that each load cell outputs a 0-10 vdc so we ordered a 1746-NI4 module. I was going to sum the inputs, divide by 3 and then scale the data. After looking them over today, we discovered that its only a millivolt output with no amplifier and now at the the last minute, we are scurrying to order amps and power supplys tomorrow.
