Hi everyone,
my name is John and i am a student at the technical university of Patras,
Greece.
I could really use some help here, with this RTD "PT 100" temperature
sensor.
I have developed a temperature data acquisition system using a card,
connected to my
PC serial port. I have tested it by using a LM 35 (requires Vcc = 5V)
temperature sensor and it works.
The thing is that i want to adjust a PT 100 temperature sensor.
I bought one but...
The PT 100 has 4 wires (2 white, 2 Red), i have tried using my multimeter to
measure the output
but it doesn'y work (PT 100 ouput 1mV/Celsium). If i connect it to my card
then i get 0 input.
Does anyone has any idea or experience about PT 100 temperature sensors.
Thanks in advance
