 Pressure sensor 4-20 mA Kategorie: Programmierung Basic (von Hans - 9.02.2006 21:36)

Hallo

I have one more problem ,
IÂ’ve a pressure  sensor 4 to 20 mA
This  go on 250 ohm.
So I have 1 to 5 volt on the 8 bit A/D entrence.
1 volt is 1/5  from the A/D port.
At the formule as, for example, the pressure sensor is  0 to 250 bar

IF Adport1>51 THEN Sensor1=Adport1-51 ELSE Sensor1=0
Sensor1=Sensor1*(250/204)

This is working
But itÂ’s to grove
The next question is:
Is there a way , or a chip,  bijv.  10 bits AD ingang
