Hi, I've a pressure sensor , which is connected to a uC , and we used it for a tension machine which measures the strength of metals like ferrite , the sensor have a strange voltage its 40V AC , i measured it from earth to it , i dont know from where this residual voltage on it , and when i discharge this charge, it works good , i dont know from where this builds up .. what could be the problem ??
