Dear Sirs,

We are thinking about purchasing a ADC-020 for doing pressure measurements. All pressure sensors however seem to have an output of either 0-5 Volt, or 0-450mA.
Is it possible to connect them to the ADC-020 since this logger has a maximum input of 2,5 Volts ? If so, how is it done ?

Kind regards

Hi Victor

Thank you for your post.

Do you mean the ADC-20? You can connect a high voltage to this if you use a potential divider to attenuate the voltage. You can connect a small current by using a shunt resistor and the Ohms Law calculation.

Hope this helps

Best Regards
