Logging +5V to -5V analog signal

Postby FrankL on Mon Sep 14, 2020 10:21 am

Hello

I need to log an analog signal coming from an external module converting signal from wireless torque cell, the values varies from +5V to -5V.
Is there any way to log a +5V to -5V with a C187 without using an external conversion module?

Thanks, Frank

Your going to need to shift the voltage, normally strain gauge amplifiers would have the ability to add an offset voltage.
