Sensor 4-20mA
Archiver
Posts: 46,084
Hi guys & girls,
I am working on a HVAC project. I have to read in an 4-20mA pressure
sensor (between -0,5 and 7 BAR brand DIXELL). I've searched a lot on
internet and didn't find a proper solution to connect this sensor to
my BS2P-24. I've already made an easy circuit wich contains an 12BIT
ADC and a resistor (150ohms) so I can get max 3V over my adc inputs.
When I read the ADC in, I get VERY different values. My power supply
is extremly stabled (checked with an oscilloscope). Is there
somebody who has created a simular project and could give me a
better way to connect the pressure sensor with my stamp?
Kindly regards
