CR200 PT100

Spol Mar 28, 2017 10:02 AM

How can I calculate the temperature of a PT100 sensor with a CR200? I use the ExDelSE function with a bridge and then I calculate the resistence with the formules found on the CR200 manual X=V1/Vx  and  Rs=Rf*(X/1-X)). Is there a function like the PRT found on the CR1000?

Thanks

Paolo

Hi, I believe that you have no options. There aren't instructions and even the precision to make a significant measurements with this sensor. You better use a thermistor 109 or buy a PT100 to mA / mV converter, if you just can not replace that sensor.
